A giant bilateral calcified chronic subdural hematoma.

ABSTRACT

BACKGROUND: A calcified chronic subdural hematoma is a rare disease and its neuroradiological presentation is variable. The degree of calcification extends from thin calcified inner membranes to dense calcification and even ossification of the hematoma. Previous reports described a maximum of two hematoma cavities with calcified inner hematoma membranes. METHODS: Neuroimaging report with illustrative computerized tomography images. RESULTS: A patient with a bilateral symptomatic calcified chronic subdural hematoma, or so-called "armoured brain", was admitted to our intensive care unit with clinical signs of increased intracranial pressure. Computerized cranial tomography demonstrated multiple bilaterally located hematoma cavities with thin calcified inner membranes. After neurosurgical intervention by bilateral burr hole trepanation, clinical symptoms improved. CONCLUSIONS: Our case of a calcified chronic subdural hematoma presents with an uncommon imaging pattern with more than four hematoma cavities bounded by predominantly convex- and concave-configured thin calcified inner membranes.
