Calcified chronic subdural hematoma: Case report

Abstract

The authors present a case of a female patient, 26 years old, who suffered a craniocerebral trauma 15 years ago, by falling from a different level. She manifested an intracranial hypertension syndrome and seizures at the moment of hospital admission. Brain CT scan reveals a large right fronto-parietal calcified subdural mass with left shift of median line. The lesion was isointense on T1 and hyperintense in T2 weighted magnetic resonance imaging (MRI). Calcified or atypical meningioma, bony tumor and subdural abscess were included in differential diagnosis. She underwent surgery and a calcified chronic subdural hematoma was completely excised, with good postoperative recovery. After two months of follow up, seizures were controlled with a minimal dose of medication, control CT scan showing absence of the hematoma and brain re-expansion. In summary, this uncommon calcified chronic subdural hematoma was successfully excised, resulting in a good recovery. From the literature review and the experience in this patient, authors consider surgical treatment for calcified chronic subdural hematoma as necessary and often results in neurological improvement, especially concerning seizures.
