Polyarteritis nodosa (PAN) is a chronic inflammatory disorder characterized by a necrotizing vasculitis of small and medium-sized artery, which can involve several organs, such as, the kidney, skin, peripheral nerves, muscle, heart, and gastrointestinal tract. In addition to systemic involvement of the classical PAN, a localized disease of the gallbladder, uterus, testis, and skin has been reported. In particular, a limited involvement of the breast is an unusual manifestation of PAN and usually runs a favorable prognosis when compared with the classical PAN. We describe a 64-year-old female patient who had a limited disease of PAN on both the breasts. She presented with mass-like lesions on both the breasts. After surgical excision of the breast lesions, she has been doing well with only a low dosage of prednisolone.

The authors collected 53 consecutive cases of chronic subdural hematoma which were diagnosed by carotid angiography and brain scanning. There were 39 males and 14 females. The mean age was 45.6 years old. 80% of all cases had a history of head injury and one of the clinical manifestations of increased intracranial pressure as well as contralateral hemiparesis. The most common site of hematoma was fronto-parietal region. 42 cases were treated with simple drainage and 11 cases with membranectomy. Post-op. course was excellent in all cases of simple drainage, but in 2 cases of membranectomy, recollection of hematoma developed after surgery.
