Question 41: Which of the following is incorrect about the condition shown below?

• A. Most common CT finding is intraventricular calcification (Correct Answer)
• B. Most common presentation is partial seizures
• C. Albendazole is given for 8 days
• D. Steroids help in alleviating vasogenic oedema of ring enhancing lesion

Explanation: ***Most common CT finding is intraventricular calcification*** - This statement is **incorrect**. In neurocysticercosis, the most common CT finding is **parenchymal calcifications**, which represent the remnants of dead cysts, rather than intraventricular calcifications. - **Intraventricular calcifications** are possible but less frequent than parenchymal lesions and often arise from degenerating intraventricular cysts leading to obstructive hydrocephalus. *Most common presentation is partial seizures* - This statement is **correct**. **Partial seizures** (also known as focal seizures) are indeed the most common clinical presentation of neurocysticercosis, especially when **parenchymal cysts** are involved. - This is due to the cysts acting as a **focal irritant** within the cerebral cortex, leading to abnormal electrical activity. *Albendazole is given for 8 days* - This statement is **correct**. For neurocysticercosis, **Albendazole** is typically administered for a duration ranging from **8 days to 30 days**, depending on the number, location, and stage of the cysts. - The precise duration can vary based on clinical response and cyst resolution observed on follow-up imaging. *Steroids help in alleviating vasogenic oedema of ring enhancing lesion* - This statement is **correct**. **Corticosteroids**, such as dexamethasone, are frequently co-administered with anti-parasitic drugs like albendazole to manage the **inflammatory response** (vasogenic edema) caused by the dying parasites. - This edema often surrounds the **ring-enhancing lesions** seen on imaging and can exacerbate symptoms like seizures and headaches.
