ABSTRACT

Diagnosis: Parasellar Meningioma and arachnoid cyst

History: 42 y.o. woman with elevated prolactin. Please evaluate for
 evidence of pituitary adenoma

Findings: Avidly enhancing suprasellar mass distinct from the pituitary measuring approximately 3.3 x 2.5 x 3.5 cm. The mass surrounds the left cavernous internal carotid artery extending into the
 medial aspect of the right cavernous sinus. The tumor extends anteriorly to the left orbital apex.
 There is suprasellar and pontine cistern extension also coursing along the 
posterior margin of the majority of the clivus. There is posterior extension
 of the mass surrounding the left 5th cranial nerve involving Meckel's cave as
 well as surrounding the cisternal portion of the 5th cranial nerve. The mass
 extends to but not definitely within the left foramen ovale involving the
 left foramen rotundum as well. The mass abuts the left margin of 
the basilar artery and the left anterior margin of the mid brain. It extends 
into the posterior-superior aspect of the sphenoid sinus as well.

 A fluid intensity, non-enhancing structure is seen along the posterior margin
 of the above described mass filling the superior pontine cistern with 
extension into the left suprasellar cistern measuring 2.3x1.5x1.2 cm.

The mass involves the left cavernous sinus, surrounds the carotid, and extends forward to the orbital apex, and backward to the tentorium and clivus.
