Giant Hypothalamic Hamartoma in an Infant: A Case Report and Review of the Literature
Giant hypothalamic hamartomas (GHH) are extremely rare lesions in infants and usually intrinsically epileptogenic. We present the case of a 10 month old girl child presenting with drug resistant seizures and a giant hypothalamic lesion that was confirmed as hamartoma on histopathology. Surgical decompression and disconnection from the hypothalamus was performed with the intent of controlling her seizures. Unfortunately, the patient developed right middle cerebral artery and posterior cerebral artery territory infarction, possibly due to vasospasm or thrombosis of the vessels. The patient had a stormy postoperative course but has recovered well neurologically at the 18 month follow up. Histopathological examination revealed abnormal clusters of NeuN positive neurons, which was confirmatory of hypothalamic hamartoma. A review of the published literature on infantile GHH, its management and the postoperative complications is undertaken in this short report.
