Background:
Calcified chronic subdural hematoma (CCSDH) is a rare disease for which no standard approach to treatment has been established. Reports covering both burr hole trepanation and craniotomy for CCSDH are rare. Furthermore, infection of CCSDH after the burr hole trepanation has not been reported in the literature.
Case Description:
A 61-year-old man presented with left frontotemporoparietal CCSDH demonstrated on computed tomography (CT) scan. The patient underwent 2 separate burr hole trepanations with intraoperative irrigation and postoperative drainage. These procedures led to infection of the CCSDH. The patient eventually underwent an open craniotomy to provide complete removal of the hematoma.
Conclusions:
Owing to the complex contents of a CCSDH, burr hole trepanation cannot adequately drain the hematoma or relieve the mass effect. Craniotomy is a much more reliable approach for achieving complete resection of a CCSDH.
