CEREBRAL ARTERIAL ECTASIA AND TUBEROUS SCLEROSIS - CASE-REPORT

OBJECTIVE AND IMPORTANCE: Tuberous sclerosis is associated with a wide variety of central nervous system abnormalities. Cerebrovascular anom alies are extremely rare, but a case of cerebral arterial ectasia and giant fusiform aneurysm formation in a young child is reported. CLINIC AL PRESENTATION: A 5-month-old male patient with tuberous sclerosis pr esented with seizures, a subependymal tumor, and intraventricular hemo rrhage. Cerebral angiography demonstrated a large fusiform aneurysm of the left cavernous internal carotid artery as well as arterial ectasi a of the proximal left anterior cerebral and middle cerebral arteries. The patient developed hydrocephalus and died of infectious complicati ons after repeated shunt procedures. CONCLUSION: Tuberous sclerosis is commonly associated with central nervous system lesions. Although rar e, cerebrovascular anomalies and aneurysms should be considered in the differential diagnosis of mass lesions to avoid an ill-advised biopsy of a vascular lesion, which could have disastrous consequences.
