Miiller has recorded very carefully the clinical historyand an account of the subsequent dissection of a very 160 GONNEGTIVE-TISSUE TUMOURS unusual example of plexiform angeioma. The patient, aman of 20 years, stated that his parents noticed a red spoton the left half of the forehead when he was a year old;this gradually increased in size, and at the age of 12 ithad become an obvious tumour. When the patient was16 it not only grew rapidly, but began to buzz. Atthe age of 20 the tumour exhibited all the characters. Fig. 85.—Dissection of a plexiform angeioma of the forehead. (j4fter H.

Thepatient became hemiplegic on the second, and died on thethird day after the operation. Death was due to embolismand thrombosis of the left middle cerebral artery. Theparts were injected and dissected (Fig. 85); the angulararteries were large and very tortuous. Plexiform angeiomas occur in connexion with the ANGEIOMAS 161 cerebral arteries. They have been observed on the surfaceof the right anterior lobe of the cerebrum, fed mainly bythe anterior and middle cerebral arteries. In two casesreported by Drysdale, one patient was a lad 17 years ofage, and the other a woman aged 26 years. The womanwas an epileptic. In another patient, a man aged 20, theangeioma wa
