Abstract

Background: Colloid cysts are rare intracerebral lesions that are preferentially encountered within the third ventricle. There are only a few reports in which colloid cysts are described in other locations such as the fourth ventricle, brainstem, cerebellum and suprasellar region.

Clinical description: Young female had presented with headache since one year and on episode of generalized tonic, clonic seizures one week ago. She had bitemporal visual field cuts on examination. Imaging showed a hyperdense suprasellar lesion which was isointense on T1 weighted MR images, profoundly hypointense on T2 weighted images, and did not show any enhancement on post contrast MR study. It showed no restriction on DWI. A pteronal craniotomy and total excision of the lesion was done and the patient recovered well with no further neurological deficits. Pathology was consistant with a colloid cyst.

Conclusion: Colloid cyst is rarely found in suprasellar location. Such a rare diagnosis has to be considered in the differential diagnosis in patients who present with a suprasellar cystic lesion.
