Diagnosis
AIDS complicated cerebral infarction.
Discussion
Patients with HIV infection have hyperplasia and granuloma of the inner wall of the blood vessels due to its nature of vessel-philia, leading to vascular stenosis or bleeding. For this case, the patient is young with CT scanning and MR imaging demonstrations of left temporal lobe atrophy, enlarged cerebral ventricles and later fissure cistern and with MRA findings of distal vascular stenosis of left cerebral middle-sized artery, arising from distal vascular inner membrane thickening and granuloma of left cerebral middle-sized artery due to HIV infection and the following blood supplying disturbance. Causes of limited cerebral atrophy among non-AIDS patients are degenerative diseases, such as cerebral trauma, infection, cerebrovascular diseases, cerebral dysplasia and Pick’s disease, etc. that usually is found in senior citizens. The causes of limited cerebral atrophy are different, but its CT scanning and MR imaging demonstrations are almost the same. CT scanning and MR imaging demonstrate signs of cerebral atrophy and abnormal signs of different primary diseases. The diagnosis can be made based on the combination with case history.
