Lymphocytic hypophysitis is an autoimmune condition that commonly presents in women of childbearing age as hypopituitarism and a sellar mass.

A 66-year-old woman presented with anterior pituitary dysfunction. Computed tomography imaging revealed a small hypodensity that was not felt to be the cause of the pituitary dysfunction. Eight years later, her vision rapidly deteriorated and MRI showed a pituitary mass lesion causing optic chiasm compression. Histological examination of the partially resected gland revealed evidence of lymphocytic hypophysitis.

Our patient is an example of the variable presentation and course of lymphocytic hypophysitis. Such a long latent period between the initial presentation of adenohypophysial hypofunction and optic chiasm compression due to an enlarging pituitary mass has not been reported.

Endozepine-4 stupor is a rare disorder. It presents with recurrent episodes of stupor and coma. Endozepine-4 levels are elevated during an attack with electroencephalogram showing fast activity during the ictal phase. There is no specific treatment and various drugs have been tried without long-term benefit.

We used the vigilance promoting drug modafinil to prevent such attacks in a case presented with endozepine stupor.

The vigilance promoting drug modafinil prevented recurrent episodes of stupor and coma in this patient at a dose of 200 mg/day for a period of six months. Upon withdrawal of the drug, the patient experienced recurrent episodes and on reinstitution of modafinil she has remained asymptomatic in the following one year.

Neurenteric cysts are congenital cysts of the central nervous system that are believed to be of endodermal origin. In this report we present the unique case of a supratentorial neurenteric cyst that is contained entirely within the brain parenchyma.

Apatient presented with an intraparenchymal cystic lesion that was subsequently identified as a neurenteric cyst. This lesion is reviewed in light of the available literature.

A 35-year-old female presented with a one year history of progressive headaches and seizure-like episodes. Her examination revealed no deficits. Magnetic resonance imaging showed a 4 cm x 4 cm x 4 cm cystic lesion within the parenchyma of the right frontal lobe. A right frontal craniotomy and complete excision of the cystic lesion was performed. Pathologic examination confirmed that it was a neurenteric cyst. Postoperatively the patient's symptoms improved.

Review of the literature revealed this to be the first case of a surgically excised, pathologically confirmed supratentorial neurenteric cyst, contained entirely within the brain parenchyma.
