The therapeutic options for arteriovenous malformations (AVMs) of the thalamus and the basal ganglia have expanded to include preoperative embolization, stereotactic radiation, and microsurgery. Adjuncts to surgery such as stereotactic guidance, electrophysiological monitoring, intraoperative ultrasound, intraoperative angiography, and induced hypotension have significantly reduced postoperative morbidity. We review the management and outcome of 65 consecutive patients who were treated for deep-seated supratentorial vascular malformations; 45 patients (69%) were treated surgically, 10 patients (15%) were treated conservatively, and 10 patients (15%) underwent radiosurgery. ⋯ Among six patients who underwent surgery for cavernous angiomas, four (66%) improved, one (17%) remained unchanged, and one (17%) worsened. Operative complications included transient neurological deficits in seven patients (16%), permanent neurological deficits in six patients (13%), and new bleeding from residual AVMs in four patients (9%). Among 10 patients treated conservatively, 3 (30%) had repeat hemorrhages, 2 (20%) had progressive neurological deficits, and 1 (10%) died.(ABSTRACT TRUNCATED AT 250 WORDS)

Infantile myofibromatosis is a rare clinical entity characterized by multiple mesenchymal tumors in the neonatal period. We describe a 15-month-old girl with multicentric cranial lesions involving the parietal and occipital bones associated with a single small subcutaneous lesion in the back. ⋯ This is the first description of magnetic resonance features of multicentric infantile myofibromatosis in the cranium, and gadolinium-enhanced magnetic resonance images were useful in showing dural involvement. The importance of recognizing this disorder is emphasized because of its special clinical behavior.
