Intradural extramedullary spinal teratoma (IEST) is a rare condition in adults, with a male predominance. It is commonly associated with spinal dysraphism, lumbar puncture, and previous spinal surgery. This case is a 37-year-old male diagnosed with a mature cystic IEST without dysraphism or previous surgical interventions. ⋯ MRI is a standard tool for diagnosing IEST, but the diagnosis is confirmed by histopathological examination. Total surgical excision is the treatment of choice, but when adhesions to the neural tissue are present, subtotal excision should be attempted. The patient should be followed up with serial clinical and radiologic examinations to ensure the absence of residual mass at the site of surgery.

To analyze overall trends of elective cervical spine surgery in the United States from 2003 to 2013 with the goal of determining whether the economic downturn had an impact. ⋯ The overall elective cervical spine surgery trend was not likely impacted by the economic downturn. Posterior cervical fusions grew significantly from 2003 to 2013, whereas ACDFs and posterior decompressions decreased.

Standard imaging techniques have low predictive value for identifying sources of neck pain. Single-photon emission computed tomography (SPECT) imaging in conjunction with computed tomography (CT) provides the sensitivity of bone scanning for areas of high metabolic activity with the sensitivity of CT for anatomic localization. We evaluated the usefulness of SPECT-CT imaging in identifying pain generators in upper cervical facet arthropathy. ⋯ SPECT-CT imaging of the upper cervical spine is a potentially sensitive diagnostic test that can implicate pain generators with increased metabolic activity. We propose that SPECT-CT may be a useful adjunct in the workup for neck pain secondary to facet arthropathy that could obviate diagnostic injections.

To summarize the experience in microsurgical resection of cervical spinal cord arteriovenous malformation (AVM). ⋯ Microsurgical resection of cervical intramedullary AVMs has obtained satisfactory clinical results. Preoperative magnetic resonance angiography, computed tomography angiography, and digital subtraction angiography are useful for evaluating the angioarchitecture, which is key to the success of surgery. Intraoperative indocyanine green fluorescence angiography is an important aid in the surgical treatment of spinal AVMs.

Pituitary tumor apoplexy can result from either hemorrhagic or infarctive expansion of pituitary adenomas, and the related mass effect can result in compression of critical neurovascular structures. The time course of recovery of visual field deficits, headaches, ophthalmoparesis, and pituitary dysfunction after endoscopic transsphenoidal surgery has not been well established. ⋯ Endoscopic transsphenoidal surgery can provide durable resolution of symptoms for patients presenting with pituitary tumor apoplexy. Recovery from headaches, visual, and pituitary dysfunction may be more rapid compared with ophthalmoparesis.
