Juvenile angiofibroma-CT
Juvenile angiofibroma (JNA) is a benign tumor that tends to occur in the nasopharynx of prepubertal and adolescent males. This is 14year old male with epistaxis. The tumor starts adjacent to the sphenopalatine foramen. This tumour is enhancing, bilobed or dumbbell-shaped, with one portion of the tumor filling the nasopharynx and the other portion extending to the pterygopalatine fossa. This mass is seen to erode into sphenoid sinus and displaces the posterior antral wall anteriorly (antral bow sign)

This is so fine to use the term " Antral sign" in CT scan of JNA. Historically this sign is refered to Waterz radiography of skull base. And it is the most suggestive finding in JNA.
