Intraventricular hydatid cyst causing entrapped temporal horn syndrome: Case report and review of literature
A 8 year old girl child presented in casualty in drowsy state. She had complaints of generalized headache since last four months associated with gradual diminution in vision. There was no history of vomiting or any focal neurological deficit. She was receiving treatment with some private practitioner but was not relieved.\nThe patient was drowsy, and was not oriented with time place or person. There was no apparent cranial nerve palsy or any evidence of focal neurologic deficit. Bilateral papilledema was present. Magnetic resonance imaging showed trapped temporal and occipital horn of right lateral ventricle with marked perifocal edema with minimal subfalcine herniation [].\nThe patient underwent urgent right temporal craniotomy. The right occipital and temporal horns were found dilated. Cerebrospinal fluid came out with pressure. A well defined cystic mass lesion was found in the region of trigone. The cyst was marsupialized and obstruction due to the cyst relieved.\nMicroscopically, the typical laminated cyst wall could be seen and the compressed surrounding tissue showed mononuclear inflammatory cell infiltrates. Diagnosis of hydatid cyst was confirmed [].\nPost operative period was uneventful. Follow- up showed complete recovery in headache and papilloedema. There was no evidence of other cyst on chest X-ray and ultrasound abdomen.
