Symptomatic calcified chronic subdural hematoma in an elderly patient: a case report

Abstract

Abstract Introduction Calcified chronic subdural hematoma is a rare and infrequent diagnosis made in clinical practice according to the literature. Calcification of chronic subdural hematoma is found more frequently in children and young adults than in the aged. The proposed mechanism of calcification may involve poor circulation and absorption in the subdural space together with intravascular thrombosis and prolonged existence of the hematoma in the subdural space. Clinical presentation An 84-year-old Ethiopian male patient presented with progressive right-sided body weakness of 8-month duration. The weakness started in the right lower extremity and progressively involved the upper extremity. Associated with the above complaint, he had had also a globalized headache of the same duration. Pre- and post-contrast brain computed tomography scans showed a right hemispheric extra-axial collection that crossed the suture line, with a maximum depth of 2.3 cm. Subsequently, craniotomy and hematoma evacuation were carried out and the patient was discharged improved. Conclusion The most common symptom of calcified chronic subdural hematoma is headache followed by lethargy, confusion, memory impairment weakness, and seizures. A diminished level of consciousness is relatively common and motor deficits are usually manifested as hemiparesis or gait disturbance. Most calcified chronic subdural hematomas can be diagnosed by computed tomography or magnetic resonance imaging and differentiated from the usual chronic subdural hematoma by imaging studies and gross pathology. Surgical treatment is advised in symptomatic patients when feasible, and often results in neurological improvement. Here we presented a patient with an uncommon calcified chronic subdural hematoma, which was successfully evacuated, resulting in a good recovery.
