Pediatric posterior circulation aneurysms are rare, complex, poorly understood lesions on which only limited literature is currently available. We report our 12-year experience of managing this condition to enhance knowledge of this rare entity. ⋯ Vertebrobasilar junction and vertebral artery was the most common location for posterior circulation aneurysms and most were dissecting aneurysms. Endovascular treatment was the mainstay of management. Overall good outcome was observed at long-term follow-up.

To determine the clinical and radiologic outcome of patients with acoustic neuroma (AN) treated with linear accelerator (LINAC) or CyberKnife-based stereotactic radiosurgery with respect to tumor control, preservation of serviceable hearing, and toxicity. ⋯ Our study shows that in AN, high tumor control and considerable hearing preservation rates can be achieved by single-dose radiosurgery at low toxicity rates, resulting in a positive impact on long-term clinical outcome.

Actinomycosis is an uncommon chronic suppurative infection that rarely affects the central nervous system (CNS). It is caused by filamentous Gram-positive anaerobic bacteria that is a normal commensal but causes suppurative and granulomatous inflammation after disruption of anatomical barriers. We report the largest series of 17 histologically confirmed cases of CNS actinomycosis and review clinical, imaging, and histopathologic features. ⋯ Histopathology remains the cornerstone for diagnosis of actinomycosis as on culture confirmation is very rare.

The signs and pathomechanism of Miyazaki syndrome is presented through the case of a young female patient. ⋯ The article discusses the available literature suggesting the underlying cause in such cases to be the dysfunction of the Starling resistor mechanism due to an improperly adjusted ventriculoperitoneal shunt, which results in excessive cerebrospinal fluid loss accompanied by consequent cerebral venous overflow with vertebral venous engorgement and compressive cervical myelopathy.

Transpedicular Intrabody Cage Insertion with Posterior Spine Stabilization in Kümmell Disease: Report of 2 Cases.
Kümmell disease has been treated with multiple surgical approaches, as described in the literature. However, there are few reports describing the technique of transpedicular intrabody cage insertion to enhance bony fusion and maintain the height of the vertebral body. We describe the technique of transpedicular intrabody cage insertion with posterolateral fusion in patients with Kümmell disease. ⋯ Transpedicular intrabody cage insertion is a safe and effective procedure for treating vertebral osteonecrosis to achieve bone formation at the site of vertebral osteonecrosis and to maintain body height.
