title: Low flow (cryptic) arteriovenous malformation and spontaneous haematoma.
abstract: The authors emphasize the meticulous search for microangioma under magnification in cases of spontaneous haematoma. Two cases of low flow (cryptic) arteriovenous malformations are described. The CT scan and angiography are non-contributory in detecting such lesions. These small-sized angiomas are buried in the wall of the haematoma cavity. Histologically there is evidence of thrombosis in arteriovenous malformation.
