Cystic schwannoma of the orbit-a case series.

A schwannoma is an uncommon benign orbital tumor that arises from Schwann cells in the peripheral nervous system. Schwannoma with cystic degeneration is an even more rarely reported entity. Clinical examination alone is inadequate for the diagnosis.

Thrombosed orbital varix -- a correlation between imaging studies and histopathology.

A thrombosed varix in the orbit is comparatively rare. Clinical examination alone is often inadequate for diagnosis. Radio-logical examination, such as a computed tomography (CT) scan of the orbit, is extremely important.
