Q: Pott's puffy tumour is a:

Subperiosteal abscess associated with osteomyelitis of frontal bone. ***Subperiosteal abscess associated with osteomyelitis of frontal bone*** - **Pott's puffy tumor** is a rare but serious complication of **frontal sinusitis**, characterized by an overlying edema and subperiosteal abscess. - It arises from **osteomyelitis of the frontal bone**, which can erode through the bone and lead to an intracranial abscess. *Tuberculosis of the skull bone* - While tuberculosis can affect bones, a **tuberculosis of the skull** would typically present with a more chronic course and different imaging findings, not the characteristic acute, localized swelling of Pott's puffy tumor. - **Pott's puffy tumor** is specifically associated with bacterial sinusitis, not mycobacterial infection. *Fungating scrotal malignancy* - This option refers to a **malignant tumor of the scrotum** and is entirely unrelated to skull pathology or infection. - The clinical presentation and location are completely different from Pott's puffy tumor. *Squamous cell cancer of scalp* - A **squamous cell cancer of the scalp** is a type of skin malignancy, which would present as a growing lesion and potentially ulcerate, but would not typically involve the deeper bone in the characteristic way of Pott's puffy tumor. - It does not involve a **subperiosteal abscess** or underlying osteomyelitis of the frontal bone.
