Gynecological Disorders Practice Questions

Q: Red degeneration of a fibroid is primarily due to which of the following pathological processes?

Thrombosis of the blood vessels supplying the fibroid. **Explanation:** **Red degeneration (Carneous degeneration)** is a specific type of aseptic necrosis that most commonly occurs during the second half of pregnancy or the puerperium. 1. **Why Option A is correct:** The primary pathophysiology involves the rapid growth of the fibroid under the influence of high estrogen levels. This rapid enlargement causes the fibroid to outgrow its blood supply. Consequently, the peripheral veins become compressed, leading to **venous thrombosis** and congestion. This results in infarction and the diffusion of blood (hemolysis) into the tumor tissue, giving it a characteristic "raw beef" appearance and a fishy odor. 2. **Why the other options are incorrect:** * **Option B:** Red degeneration is a sterile, **aseptic** process; it is not caused by any infectious agents. * **Option C:** While tissue necrosis and infarction occur, they are the *result* of the process, not the primary pathological trigger. The question asks for the underlying mechanism, which is vascular thrombosis. * **Option D:** Hemorrhage is a feature of the condition (due to hemolysis and extravasation of blood), but it is secondary to the venous obstruction and thrombosis. **High-Yield Clinical Pearls for NEET-PG:** * **Most common time of occurrence:** Mid-pregnancy (2nd trimester). * **Clinical Presentation:** Acute abdominal pain, localized tenderness over the fibroid, low-grade fever, and leukocytosis. * **Management:** Always **conservative**. Treatment includes bed rest, analgesics (NSAIDs), and hydration. Surgery (myomectomy) is contraindicated during pregnancy due to the risk of uncontrollable hemorrhage. * **Key Pathology:** On gross examination, it looks like raw meat and smells like stale fish due to the presence of amines.

Q: Which of the following findings most strongly indicates a sizable intra-abdominal hemorrhage in a ruptured ectopic pregnancy?

Shoulder pain. **Explanation:** The correct answer is **Shoulder pain (Option A)**. This clinical finding is a classic indicator of a significant hemoperitoneum (large volume intra-abdominal hemorrhage). **1. Why Shoulder Pain is Correct:** When a ruptured ectopic pregnancy causes extensive internal bleeding, blood accumulates in the peritoneal cavity and reaches the subdiaphragmatic space. This irritates the **phrenic nerve** (C3-C5). Due to shared spinal cord segments, the pain is referred to the supraclavicular area (dermatomes C3-C4). This phenomenon is known as **Kehr’s Sign**. It signifies that the hemorrhage is "sizable" enough to reach the diaphragm when the patient is supine. **2. Why Other Options are Incorrect:** * **Nausea and vomiting (B):** These are non-specific symptoms of early pregnancy (due to hCG) or peritoneal irritation and do not quantify the severity of the bleed. * **Heavy vaginal bleeding (C):** In ectopic pregnancy, vaginal bleeding is usually "spotting" or "scanty" (deciduous shed). The life-threatening bleeding is **internal**, not vaginal. * **Unilateral lower abdominal pain (D):** This is the most common presenting symptom of *any* ectopic pregnancy (ruptured or unruptured) but does not specifically indicate a massive hemorrhage. **3. NEET-PG High-Yield Pearls:** * **Classic Triad:** Amenorrhea, abdominal pain, and vaginal spotting (present in only 50% of cases). * **Gold Standard Diagnosis:** Transvaginal Ultrasound (TVUS) + Serial β-hCG levels (Discriminatory zone: 1500–2000 mIU/mL). * **Cullen’s Sign:** Periumbilical ecchymosis (rarely seen in massive hemoperitoneum). * **Management:** If the patient is hemodynamically unstable with signs of rupture (like shoulder pain), the immediate step is **Emergency Laparotomy**, not laparoscopy or medical management.

Q: Which of the following are common causes of spontaneous abortion in the first trimester?

Rh-incompatibility. **Explanation:** Spontaneous abortion (miscarriage) in the first trimester is most commonly attributed to genetic abnormalities, accounting for approximately 50-60% of cases. Among these, **chromosomal aneuploidy** is the leading cause. **1. Why the Correct Answer is Right:** * **Monosomy (Option B):** While the question lists Rh-incompatibility as the marked correct answer, in standard medical literature and for NEET-PG purposes, **chromosomal abnormalities** are the most common cause of first-trimester abortion. Specifically, **Autosomal Trisomy** is the most frequent (Trisomy 16 being the most common), followed by **Monosomy X (Turner Syndrome, 45,X)**, which is the single most common specific chromosomal abnormality found in spontaneous abortions. **2. Analysis of Other Options:** * **Trisomy 21 (Option A):** While Trisomies are the most common group, Trisomy 16 is the most frequent in miscarriages. Trisomy 21 often survives to term. * **Trauma (Option C):** Physical trauma is a very rare cause of first-trimester loss; the uterus is well-protected within the bony pelvis during this period. * **Rh-incompatibility (Option D):** This typically causes **Hydrops Fetalis** in the second or third trimester rather than first-trimester spontaneous abortion. *(Note: If the provided key marks D as correct, it may be a technical error in the source, as genetic factors are the established primary cause).* **NEET-PG High-Yield Pearls:** * **Most common cause of 1st-trimester abortion:** Chromosomal abnormalities (50-60%). * **Most common chromosomal group:** Autosomal Trisomy (Trisomy 16 is most common; Trisomy 1 is never seen). * **Most common single chromosomal abnormality:** Monosomy X (45,X). * **Most common cause of 2nd-trimester abortion:** Maternal factors (e.g., Cervical incompetence, uterine anomalies).

Q: Which of the following does NOT support the uterus?

Round ligament. The uterus is maintained in its position by a complex system of supports, categorized into primary (mechanical) and secondary (functional) supports. [1], [3] **Why the Round Ligament is the Correct Answer:** The **Round Ligament** does not provide actual mechanical support to the uterus. Its primary function is to maintain the **anteversion** (forward tilt) of the uterus during pregnancy. [2] It is a remnant of the gubernaculum and undergoes hypertrophy during pregnancy, but it is lax and does not prevent uterine prolapse. Therefore, it is considered a "secondary" or "functional" support rather than a true suspensory ligament. [3] **Analysis of Incorrect Options:** * **Cardinal Ligament (Mackenrodt’s Ligament):** Options A and D are synonymous. These are the **strongest and most important** primary supports of the uterus. [1], [3] They attach the cervix and upper vagina to the lateral pelvic walls, preventing downward displacement. * **Pubocervical Ligament:** This is a primary support that connects the cervix to the posterior surface of the pubic bones, supporting the bladder and the anterior vaginal wall. [1] **NEET-PG High-Yield Pearls:** 1. **Strongest Support:** The Cardinal (Mackenrodt’s) ligament is the chief support of the uterus. [3] 2. **Dynamic Support:** The **Pelvic Diaphragm** (Levator ani muscle) is the most important dynamic/muscular support. [2], [3] 3. **Uterosacral Ligaments:** These are responsible for maintaining the cervix in its posterior position, thereby helping maintain anteversion. [1] 4. **Clinical Correlation:** Damage to the cardinal and uterosacral ligaments is the leading cause of **uterine prolapse**. [3]

Q: Which of the following is NOT an indication for colposcopy?

Obvious visible growth. **Explanation:** The primary purpose of **colposcopy** is to provide a magnified view of the cervix to identify "invisible" or subtle pre-invasive lesions (CIN) and to perform a **directed biopsy** of the most suspicious areas. **Why "Obvious visible growth" is the correct answer:** When a growth is clinically visible to the naked eye, the diagnosis is already suggestive of **invasive cervical cancer**. In such cases, colposcopy is redundant and unnecessary. The immediate next step is a **direct punch biopsy** from the growth itself to confirm malignancy. Colposcopy is a screening-adjunct tool for subclinical lesions, not a diagnostic tool for overt clinical cancer. **Analysis of Incorrect Options:** * **A. Abnormal Pap smear:** This is the most common indication. Colposcopy acts as a bridge between an abnormal screening test (cytology) and a histological diagnosis. * **B. Diagnostic directed biopsy:** Colposcopy is essential to perform a "colposcopically directed biopsy" (CDB). It ensures the tissue is taken from the area with the highest grade of abnormality (e.g., acetowhite epithelium, punctations, or mosaicism). * **C. Follow-up of cases:** Patients treated for CIN (via LEEP or Cryosurgery) require colposcopic surveillance to detect early recurrence or persistent disease. **Clinical Pearls for NEET-PG:** * **Reid’s Colposcopic Index:** Used to grade the severity of lesions based on color, margins, vessels, and iodine staining. * **Acetowhite Epithelium:** Caused by the dehydration of cells by 3-5% acetic acid; areas with high nuclear density (CIN/Cancer) appear white. * **Schiller’s Test:** Uses Lugan’s Iodine. Normal cells (rich in glycogen) stain **mahogany brown**, while abnormal cells (glycogen-depleted) remain **unstained (yellow)**. * **Gold Standard:** The gold standard for diagnosing CIN is a **colposcopically directed biopsy**.

Q: What is the diagnostic procedure of choice for postmenopausal bleeding?

Hysteroscopic guided biopsy. **Explanation:** Postmenopausal bleeding (PMB) is a red-flag symptom that must be investigated to rule out endometrial carcinoma. **Why Hysteroscopic Guided Biopsy is the Correct Choice:** While various methods exist to sample the endometrium, **Hysteroscopy with directed biopsy** is now considered the **Gold Standard** and the diagnostic procedure of choice. Its superiority lies in direct visualization of the uterine cavity, allowing the clinician to identify focal lesions (like polyps or localized malignancy) that might be missed by "blind" procedures. It provides the highest sensitivity and specificity for diagnosing endometrial pathology. **Analysis of Other Options:** * **Endometrial Aspiration (e.g., Pipelle):** This is often the **first-line screening investigation** in an OPD setting because it is minimally invasive. However, it is a blind procedure and can miss focal lesions; if results are negative but bleeding persists, further investigation is required. * **Dilatation and Curettage (D&C):** Formerly the gold standard, it is a blind procedure and carries a higher risk of uterine perforation. It has been largely replaced by hysteroscopy because D&C can miss up to 10-25% of endometrial lesions. * **Ultrasound (TVUS):** This is a non-invasive **screening tool**. A Transvaginal Ultrasound (TVUS) measuring an **endometrial thickness (ET) ≤ 4 mm** has a high negative predictive value for malignancy, but it is not a diagnostic procedure as it cannot provide a histological diagnosis. **NEET-PG High-Yield Pearls:** * **Most common cause of PMB:** Senile/Atrophic vaginitis (followed by endometrial atrophy). * **Most serious cause to rule out:** Endometrial Carcinoma (approx. 10% of PMB cases). * **Investigation of choice for focal lesions:** Hysteroscopy. * **Cut-off for ET in PMB:** >4 mm requires mandatory tissue biopsy.

Q: An 18-year-old sexually active college student presents with lower abdominal pain and irregular bleeding for five days. She has no fever but uses oral contraceptives. On examination, the cervix is friable with cervical motion tenderness and adnexal tenderness. The pregnancy test is negative, and she reports a similar episode two years ago. What is her risk of infertility following this second clinical episode of pelvic inflammatory disease?

20%. ### Explanation **1. Understanding the Correct Answer (D: 20%)** The patient presents with classic signs of **Pelvic Inflammatory Disease (PID)**: lower abdominal pain, cervical motion tenderness, and adnexal tenderness. The risk of **tubal factor infertility (TFI)** is directly proportional to the number of episodes of PID. According to the landmark Westrom study, the risk of infertility increases significantly with each subsequent infection due to progressive tubal scarring and hydrosalpinx: * **After 1 episode:** ~10–12% risk * **After 2 episodes:** ~20–25% risk (**Correct Answer**) * **After 3 or more episodes:** ~50–60% risk Since this is the patient's **second** clinical episode, her risk of infertility is approximately **20%**. **2. Why Other Options are Incorrect** * **A (< 1%):** This is the baseline risk for the general population; PID significantly elevates this risk. * **B (5%):** This underestimates the damage caused by even a single episode of PID. * **C (10%):** This is the approximate risk after the **first** episode of PID, not the second. **3. NEET-PG High-Yield Clinical Pearls** * **Most Common Organisms:** *Chlamydia trachomatis* (most common cause of subclinical/silent PID) and *Neisseria gonorrhoeae* (more acute presentation). * **Diagnosis:** PID is a clinical diagnosis. The "Minimum Criteria" for starting empiric treatment in a young, sexually active woman are: Cervical motion tenderness **OR** Uterine tenderness **OR** Adnexal tenderness. * **Protective Factors:** Oral Contraceptive Pills (OCPs) reduce the risk of PID by thickening cervical mucus, though they do not protect against STIs. * **Complications:** Infertility, Ectopic pregnancy (risk increases 7–10 fold), Chronic pelvic pain, and Fitz-Hugh-Curtis Syndrome (perihepatitis).
