Arachnoid cyst rupture with subdural hygroma: case report and literature review.

Arachnoid cyst rupture causing subdural hygroma is rare. Twenty-one cases have been previously reported in the literature. We report a case of a 9-year-old boy presenting signs and symptoms of increased intracranial pressure due to the rupture of a type III arachnoid cyst causing subdural hygroma. The clinical and radiological findings as well as the management of the patient are discussed in relation to the pertinent literature.

Multifocal intradiploic cavernous hemangioma of the skull associated with nasal osteoma.

OBJECTIVE: To present a 42-year-old female patient with multifocal cavernous hemangioma of the skull associated with nasal osteoma. DESIGN: A case report. INTERVENTION METHODS: X-rays, computerized tomography, magnetic resonance imaging, and histopathology were used to achieve the diagnosis of this rare entity. The multiple cavernous hemangiomas were resected en-bloc and a curettage biopsy was obtained from the nasal osteoma. RESULTS: The patient healed well after the operation. No recurrences of the cavernous hemangiomas were observed after one-year follow-up. CONCLUSION: Multifocal cavernous hemangiomas are rare benign lesions of the calvarium, arising from the intrinsic vasculature of the bone. Although they are benign, radiological findings are not always characteristic and their multiple presentation may easily make surgeons consider the other malignancies of the skull in the differential diagnosis. Histopathologic confirmation of the tumor is the definitive method for diagnosis. The treatment of choice is early en bloc resection of the tumour where it is possible.
