Multiple scalp aneurysms caused by atypical temporal arteritis--case report.
A 55-year-old male suffered sudden onset of dysarthria and mild left hemiparesis due to a right intracerebral small hemorrhage. On admission, six subcutaneous elastic hard lumps were found on the scalp with painless and regular pulsation. The lumps were located along the course of the bilateral superficial temporal arteries (5 locations) and the occipital artery. The patient did not have symptoms of headache or blurred vision associated with temporal arteritis. The largest lump was removed for cosmetic reasons and definitive diagnosis. Histological examination demonstrated many infiltrating inflammatory cells along the entire vascular wall but without giant or fibrinoid necrosis. These multiple scalp aneurysms were probably caused by atypical temporal arteritis.
