Аннотация
BACKGROUND: Bannayan-Zonana syndrome is a rare hamartomatous disorder, characterized by macrocephaly, multiple lipomas, and hemangiomas. Inheritance is by autosomal dominant transmission with few reported sporadic cases. Male predominance is also reported.
METHODS: We describe a patient who presented with multiple subcutaneous lipomas, mild macrocephaly, and an extradural spinal hemangioma. Other affected family members and 24 other previously reported cases are discussed.
RESULTS: Spinal hemangiomas have not been described previously with this syndrome. The patient also had a "malignant bone tumor" removed from his humerus 20 years ago. Two of the patient's siblings also had lymphoma, which is an unusual accompaniment not reported previously. Only the male members in the family showed multiple subcutaneous lipomas.
CONCLUSION: Some patients with Bannayan-Zonana syndrome may have hamartomatous lesions producing cord compression or intracerebral hemorrhage, or they may rarely have other malignant tumors; therefore it is important that neurosurgeons are aware of the entity. The early diagnosis of BZS is also important for genetic counseling.
