[Cases of cavernous hemangioma discovered in patients with post traumatic intracerebral hematoma].

Cavernous haemangioma has various forms. The cases with spontaneous intracerebral haemorrhage are most common, but post-traumatic intracerebral haematoma was not reported. The aim of this report is to present cases of cavernous haemangioma with unusual clinical course. In seven patients with post-traumatic intracerebral haematoma, fragments of histologically confirmed cavernous haemangioma tissue situated in the place of haematoma were found. In one case, delayed intracerebral haematoma twenty four hours after trauma and initial CT-scan was observed. On the initial CT-scan in this patient only traumatic changes in the brain without haematoma or tumour were present. In our cases, cavernous haemangioma was situated most frequently in frontal and temporal region, shown as haematoma usually 24 hours after trauma, mainly in men in age range 30-44 years with disorders of consciousness (GCS 11). As the result of operation, the majority of patients (6 out of 7) were discharged as self-independent. The authors reviewed the literature for cavernous haemangioma. The tumour may be present in any region of the brain including infratentorial region. The lesion is disclosed most frequently in children as spontaneous brain haemorrhage and rarely as seizures or intracranial hypertension. Final diagnosis is based on cerebral angiography or MRI. CT-scans are not typical and before the appearance of haematoma do not suggest the presence of tumour. Surgical removal of haematoma with tumour fragments is the main method of therapy, but radiation is possible in order to diminish the mass. The authors conclude that in each patient with post-traumatic intracerebral haematoma, the presence of cavernous haemangioma is possible.
