Calcified chronic subdural hematoma with subacute presentation: A case report

Abstract

Chronic subdural hematomas are a very common disease occurring spontaneously, following trauma, ventriculoperitoneal shunt and postcranial surgeries, with an incidence of 1.72-20.6 per 100,000 persons per year. But sometimes calcification may occur over the outer layer of membrane or within the collection, which may occur from 6 months to many years [1]. The exact aetiology and pathogenesis of calcification remains unknown; it was first reported by a Bohemian pathologist carl von Rokitansky, in 1884[2]. Due to its appearance sometimes, it’s calledan armoured brain [3] or matryoshka head after Russian nesting dolls [4]. Though limited cases have been reported majority of cases are asymptomatic, and surgical management is advocated for those having mass effect or neurological deficit. Inan article published in 2020 by Turgut et al total of 114 cases have been reported [5]. The total incidence of calcification in chronic subdural hematoma is about 02-2.7% [6]. We report a case that presented with a neurological deficit and was treated surgically with craniectomy and complete excision.
