We report a rare case of bony diastematomyelia associated with intraspinal teratoma. The patient was surgically treated with bony diastematomyelia and intradural teratoma resection, followed by lumbar duroplasty, and posterior fusion from L2-L4 in order to maintain the spinal stability of the approached segments. Despite the risks, it was necessary to perform early surgical treatment because of rapid neurologic deterioration. The patient had a good postoperative outcome.

The spot sign (SS) in spontaneous intracerebral hemorrhage has been reported to be a predictive factor of poor outcome; however, how SS is related with the clinical outcome remains unclear. We aimed to investigate how etiology associated with SS affects the clinical outcome of endoscopic surgery. ⋯ Intraventricular hemorrhage and postoperative rebleeding were considered to be associated with the poor outcome in patients with SS. The SS on computed tomography angiography may be valuable in predicting rebleeding and clinical outcome after surgery.

Diverse clinical manifestations have characterized reports of central nervous system involvement in Behcet disease. There is a limited number of published case reports of neuro-Behcet disease mimicking brain tumor. ⋯ We recommend management of neuro-Behcet disease based on perceived natural history risks, with the understanding that no data exist on this within patients population. A multidisciplinary team approach is always recommended because neuro-Behcet disease is an uncommon condition, especially in neurosurgical practice.

To evaluate role of fused 3-dimensional time-of-flight magnetic resonance angiography (3D-TOF-MRA) and 3-dimensional constructive interference in steady state (3D-CISS) in neurovascular compression in trigeminal neuralgia (TN) and hemifacial spasm (HFS). ⋯ Fused 3D-TOF-MRA and 3D-CISS images are a reliable, noninvasive tool for the evaluation of offending vessel and degree of affection in patients with neurovascular compression. MRA-CISS can be used for evaluation and treatment planning of neurovascular compression in TN and HFS.

Cavernous carotid fistulas (CCF) are anatomically complex vascular lesions. Treatment via the venous approach has been previously described and is highly dependent on the patency of the drainage pathways. The use of a unilateral approach to contralateral or bilateral shunts is technically challenging and not commonly described. We present our experience with the unilateral across-the-midline approach to both cavernous sinuses to treat shunts according to anatomic compartments to achieve anatomic cure. ⋯ Careful inspection of the venous anatomy and fistulization sites is critical when treating unilateral or bilateral carotid cavernous shunts. The contralateral venous route can serve as a safe approach when visualized. Crossing the midline via the anterior or posterior coronary sinuses is feasible and efficacious.
