Double-loculated Calcification Chronic Subdural Hematoma

Abstract

Calcified chronic subdural hematoma (CCSDH) is a rare pathologic entity and, until recently, has been only published as case reports. We first present a patient with a doubleloculated CCSDH who obtained good reexpansion after craniotomy to remove the thick calcified inner membrane and hematoma. In addition, we reviewed 46 cases in literature and conducted a summary about the incidence, clinical characteristics, radiologic findings, and therapeutic strategies of CCSDH. Surgical treatment for CCDSH with a sudden neurological deterioration is feasible and often results in neurological improvement; however, a crucial consideration was required in asymptomatic CCSDH. It is expected that CCSDH will be rarer in the future.

Surgical Management of the Armored Brain: Case Report of the Treatment of a Chronic Calcified Subdural Hematoma

“…A CT scan performed after this second operation showed that the volume of the hematoma had decreased and that the calcified cavity was communicating with the subdural space beneath (►Fig. 3).…”

“…1 Its overall yearly incidence ranges from 1.72 to 20.6 per 100 thousand persons. 2 Between 0.5% and 2.0% of the cases of CSDH 3 undergo calcification, and they are known as calcified DSDHs (CCSDHs); their first known description was made by von Rokytansky in 1884. 4 Due to its similarity with an armor encapsulating the brain, this entity is sometimes referred to as armored brain .…”
