Spinal arteriovenous fistula (AVF) may rarely associate with spinal dysraphism, that is, tethered spinal cord and spinal intradural lipoma. Spinal extradural angiolipoma coexisting with spinal AVF has not been reported in the literature. We reported an extremely rare case of sacral angiolipoma associated with tight filum terminale and sacral spina bifida coexisting with spinal AVF within this tumor. ⋯ Sacral extradural angiolipoma in the present case may be congenital in origin with development of an acquired spinal AVF within the tumor.

The premamillary artery (PMA) usually arises from the posterior communicating artery. Thus, an internal carotid artery (ICA) origin for PMA is rare. We report a rare case of a patient who presented with subarachnoid hemorrhage resulting from kissing aneurysms arising from the origin of the anterior choroidal artery and the aberrant origin of PMA and was successfully treated with coil embolization. ⋯ To the best of our knowledge, the present study is the first report of a ruptured saccular PMA aneurysm arising from ICA that was successfully treated with coil embolization. Three-dimensional digital subtraction angiography and cone-beam CT were useful for confirming the precise vasculature of the PMA.

The aim of this study was to document the initial experience and challenges of cervical decompression in a resource-poor region. ⋯ Despite the challenges of poverty, late presentation, and lack of basic standard instruments and equipment, patients with cervical myelopathy in the resource-poor setting had outcomes similar to other well-established centers after surgical decompression. We infer that challenges in setting up a spine unit in a resource-poor region can be circumvented safely.

Endodermal cysts of the oculomotor nerve are rare presentations. Only case reports are available to help guide clinicians with managing this rare entity. ⋯ Magnetic resonance imaging is an essential modality in the follow-up of these patients postoperatively in the setting of unchanged or deteriorated neurology. Fenestration of the cyst is appropriate first-line surgical management; however, a cysto-subarachnoid shunt is a safe consideration in recurrent, symptomatic cysts and provides sustained symptom resolution.

Ossifying fibroma (OF) is a benign tumor commonly occurring in the mandible and maxilla. Spinal involvement of OFs is of great rarity. To the best of our knowledge, only 3 cases in the thoracic and lumbar spine have been reported. ⋯ Spinal involvement of OFs seldom occurs. To the best of our knowledge, we have reported the first OF involving the cervical spine. Differentiating OFs from primary spinal tumors is necessary. OFs have locally aggressive behavior and a high risk of recurrence. Complete resection, followed by regular examinations, should be the ideal choice for treatment.
