Chronic Encapsulated Intracerebral Haematoma

Abstract

We report a rare chronic encapsulated intracerebral haematoma (CEICH). A 52-year-old man had two seizures. Unenhanced computed tomography scanning of the head revealed a hypodense tumour with clusters of calcification in the left temporal lobe. Magnetic resonance imaging of the brain showed a left temporal tumour with a hypointense centre and hyperintense periphery on T-1-weighted imaging and heterogeneous hypointensity on T-2-weighted imaging. The tumour was heterogeneously enhanced after gadolinium injection. Craniotomy was carried out and a CEICH in the left temporal lobe was completely excised. No vascular anomaly was found. The tumour was histologically confirmed to be a CEICH. The patient recovered well after the operation. In this report, we describe this rare case and discuss the characteristics of CEICH.
