RESUMO
Cerebral amyloid angiopathy (CAA) is observed in most cases of nonhypertensive subcortical hemorrhage involving elderly patients. We herein describe the case of a female in whom a convexal subarachnoid hemorrhage was observed at 55 years of age. The cerebral hemorrhage occurred repeatedly; however, no obvious vascular lesions were observed on a cerebral angiography, and no signs of microbleeding or lesions in the deep white matter were identified on magnetic resonance imaging (MRI). Partial excision of the right frontal cortex and hematoma evacuation were performed, and histopathological examination showed deposition of an acidophilic substance with positive staining for Direct Fast Scarlet (DFS) in the cerebral vascular wall. Finally, brain hemorrhage due to CAA was diagnosed. This case suggests that CAA is an important differential diagnosis in patients with localized non-aneurysmal subarachnoid hemorrhage in the convexity sulcus.
RESUMO
There have been several reports on surgical interventions in patients with adult cervical spondylotic myelopathy associated with cerebral palsy. We performed posterior fusion with pedicle and/or lateral mass screws combined with preoperative intramuscular injections of botulinum toxin in two patients. Two weeks before the surgery, we injected the patients with the botulinum toxin to alleviate cervical pain and to reduce the involuntary movement associated with cerebral palsy. Surgical results were good in both patients without rigid external fixation. Both patients were able to undergo rehabilitation after the surgery as soon as possible without any complication. We think that our pre surgical treatment with botulinum toxin is a useful optional treatment for cervical spondylotic myelopathy associated with cerebral palsy.
