A patient is suspected of having neuroangiofibroma. Investigation of choice for neuroangiofibroma is?
Correct Answer: Contrast enhanced CT scan
Description: The juvenile neuroangiofibroma or nasopharyngeal angiofibroma is a lesion of young adolescent males. The presenting symptoms are epistaxis and nasal obstruction foremost, with rarer complaints of proptosis, and involvement of cranial nerves. CT scan of the head with contrast enhancement is now the investigation of choice. It shows the extent of tumor, bony destruction or displacements. Anterior bowing of the posterior wall of maxillary sinus (often called the antral sign or Holman-Miller sign) is pathognomonic of angiofibroma.
