Review Case Reports
Calvarial hemangiomas: report of two cases and review of the literature.
Primary hemangiomas of the bone are uncommon tumors, accounting for less than 1.0% of all bone neoplasms. These tumors are mostly found in vertebral bodies. Hemangiomas are rarely seen in the calvarium, where their frequency is 0.2% of all bone neoplasms. Because of their infrequent appearance in the skull, vague symptoms, and absence of prototypical radiological findings, these tumors can be missed in many cases or may be misinterpreted as more ominous lesions like multiple myeloma or osteosarcoma. ⋯ Histopathologic confirmation of the tumor is the definitive method for diagnosis of intraosseous hemangiomas. Radiological findings are not always characteristic for calvarial hemangiomas. Due to possible complications and the possibility of effective treatment, this lesion should always be considered in the differential diagnosis of skull lesions.

A single-institution series of injuries of the upper cervical spine are analyzed retrospectively and the literature relevant to the topic is reviewed. ⋯ Candidates for surgery as the primary treatment include those with isolated ligamentous instabilities, Type III hangman's fractures and Type II odontoid fractures with dislocation more than 5 mm. In combined C1/C2 fractures the axis fracture dictates the treatment strategy. Patients who undergo dorsal procedures and have involvement of C1 have a greater chance of developing persistent pain.

Review Case Reports
Intradiploic hematoma after skull fracture: case report and literature review.
Intradiploic hematoma of the skull was first reported in 1934. The pathogenesis of this lesion is unclear. It is a very rare benign reactive process occurring after minor head trauma, with only seven cases reported in the literature to date. ⋯ The pathology of chronic diploic hematoma mimics aneurysmal bone cyst, giant cell tumor, giant cell reparative granuloma, fibrous dysplasia, eosinophilic granuloma, intradiploic epidermoid and dermoid cyst, cavernous hemangioma, circumscribed osteomyelitis, and tuberculous granuloma. Chronic diploic hematoma is a lesion that must be differentiated from various skull lesions both radiologically and histologically as it is amenable to treatment with a complete cure once excised.

Review Case Reports
Distal superior cerebellar artery aneurysm in a patient with systemic lupus erythematosus: case report.
The authors describe a case of ruptured distal superior cerebellar artery (SCA) aneurysm in a patient with systemic lupus erythematosus (SLE). ⋯ Aneurysms arising from peripheral segments of cerebellar arteries are rare, and delayed surgical clipping has been recommended for these lesions. In addition, the outcomes of SLE patients with ruptured cerebral aneurysms are reported to be very poor due to the systemic complications of SLE. However, our patient had a favorable outcome with early endovascular treatment for the ruptured aneurysm and with appropriate medical treatment for the accompanying SLE. Therefore, early endovascular coil embolization is worthy of consideration among the options for therapeutic intervention in these conditions.

Review Case Reports
Surgical resection of a cerebral arteriovenous malformation for treatment of superficial siderosis: case report.
To our knowledge, there are only two reported cases of cerebral arteriovenous malformation associated with superficial siderosis. In both cases, the patients were asymptomatic and were discovered on retrospective review of magnetic resonance imaging. ⋯ We report the first case of surgical resection of an intracranial arteriovenous malformation for the treatment of superficial siderosis. We emphasize the necessity of a detailed evaluation when superficial siderosis is suspected to localize and resect potential bleeding sources, because the disease is progressive and often irreversible.
