A female mongrel dog (2 months old, 3.4 kg) was presented with a sign of unconsciousness due to automobile accicent. Radiographic and ultrasonic examinations revealed fracture of the skull and subcutaneous hematoma. By surgical intervention, a large hematoma and a part of cerebral cortex prolapsed out of the fractured gap of the frontal bone were removed with some bone fragments. Post-surgical recovery of general physical status, neurological findings and electroencephalography were followed up as long as 3 months after the surgery.
In spite of rather rapid recovery of general physical status, improvement of the gait was less marked. Postual reactions except a hopping reaction were about normal at the 4th week after surgery.
Cranial nervous functions became almost normal by 6th week after surgery, however, visual impairment still remained.
In electroencephalography, many abnormal spikes were obsereved in frontal and vertex areas for first two weeks, however, no abnormal finding was seen for 12 weeks after the surgery.
Body weight increased up to 10 kg at 8th month atter the surgery and the normal first estrus was observed.
