Review Case Reports
Intraoperative development of contralateral epidural hematoma during evacuation of traumatic extraaxial hematoma.
Intraoperative development of an epidural hematoma contralateral to a craniotomy for acute traumatic extraaxial hematoma has been previously reported. This entity, however, has never been distinctly defined and differentiated from either the delayed or the bilateral acute epidural hematoma. We present 3 new cases of intraoperative contralateral acute epidural hematoma and review the 14 previously reported cases. ⋯ If brain displacement is not noted at craniotomy, then the contralateral hematoma is manifested by immediate postoperative neurological deterioration or intractable elevated intracranial pressure. The presence of any of these signs makes an immediate postoperative CT scan or burr holes contralateral to the original craniotomy mandatory for early diagnosis. In addition to defining "intraoperative contralateral epidural hematoma," stricter definitions of the terms "delayed epidural hematoma" (no hematoma present on the initial CT scan but one present on a later scan) and "bilateral epidural hematomas" (present on the initial scan) are proposed.

Review Case Reports
Cavernous sinus syndrome as the presentation of malignant lymphoma: case report and review of the literature.
Cavernous sinus syndrome (CSS) is an unusual presentation of malignant lymphoma. We report a patient with lymphoma that presented with CSS, and we review the literature on nine other reported cases. Sharp retroorbital pain, paraesthesia around the orbit, and complete 6th nerve palsy were dominant presenting symptoms. ⋯ The mean age of the patients was 45 years. The mean survival time after the first presenting symptom was 8.7 months. Two of the reported patients as well as our patient had disseminated disease, which became evident at autopsy.

Six patients with intramedullary cavernous malformations of the spinal cord are presented. Four men and two women presented with acute, subacute, or episodic signs and symptoms of spinal cord dysfunction, ranging in duration from 3 days to 25 years. ⋯ Neurological function either stabilized or improved postoperatively in all patients; follow-up ranged from 4 to 84 months. The increasing awareness of the propensity for recurrent hemorrhage, clinical features, and resectability of these malformations are discussed.
