T10-L3 Cystic Lesion of the Ventriculus Terminalis Presenting as Conus Medullaris Syndrome: A Case Report.
Intramedullary spinal cord cysts are benign, rare, fluid-filled lesions that can present anywhere along the craniospinal axis. However, when present at the level of the ventriculus terminalis, conus medullaris syndrome may occur. Radical resection of the cyst wall and evacuation of the cyst content are the 2 surgical procedures of choice. ⋯ Cystic lesions of the ventriculus terminalis are rare entities with a common presentation of severe, progressive neurologic impairment. Our case matches the classic presentation of conus medullaris syndrome. We describe and demonstrate through an operative video novel surgical techniques used to achieve successful fenestration of the cyst wall with remarkable neurologic symptom improvement. Moreover, the present case does not correlate with the classic radiographic characteristics available in current literature, such as involvement of 5 spinal segments.

Despite its relative rarity, the potential for loss of productive years makes aneurysmal subarachnoid hemorrhage (SAH) a considerably important entity in young adult patients (20-39 years of age). This study aimed to analyze outcomes of microsurgery (MS) and endovascular treatment (EVT) for saccular intracranial aneurysms (IAs) in young adult patients. ⋯ Both MS and EVT are safe for treating IAs in young adult patients. MS showed better durability of treatment and may be preferred over EVT in young patients in view of their longer life expectancy compared with older patients.

Randomized Controlled Trial
Clinical and Radiological Outcome of Intra-Cranial Aneurysm Clipping aided by Transit Time Flowmetry.
Since the International Subarachnoid Aneurysm Trial, coiling has been favored over clipping for intracranial aneurysms, resulting in selection of increasingly complex aneurysm configurations for clipping. We present the outcomes of clipping of aneurysms not suitable for coiling, with transit time flowmetry technology to aid monitoring of intraoperative flow. ⋯ In this study of clinical and radiological outcomes of surgically treated cerebral aneurysms not suitable for unassisted coiling, we showed positive results for these challenging aneurysms, aided by transit time flowmetry as a valuable tool, providingquantitative measurements of arterial blood flow to help achieve optimal clip placement and minimizing aneurysm residuals that may be sites of rebleeding. Adequate flow, defined as ≥50% of baseline, greatly reduces the risk of unfavorable outcome.

Laser interstitial thermotherapy for treatment of symptomatic peritumoral edema after radiosurgery for meningioma.
Symptomatic peritumoral edema (PTE) is a known complication after radiosurgical treatment of meningiomas. Although the edema in most patients can be successfully managed conservatively with corticosteroid therapy or bevacizumab, some medically refractory cases may require surgical resection of the underlying lesion when feasible. Laser interstitial thermotherapy (LITT) continues to gain traction as an effective therapeutic modality for the treatment of radiation necrosis where its biggest impact is through the control of peritumoral edema. ⋯ This case demonstrates that LITT may be a viable alternative treatment for patients with meningioma with symptomatic PTE who have failed medical therapy and require surgical intervention.

Microvascular decompression (MVD) has been the most effective long-term surgical treatment of trigeminal neuralgia (TN). However, the risk factors for poor pain control after MVD are not fully understood. ⋯ Younger patients with TN had worse long-term pain outcomes after MVD. The additional factors associated with postoperative recurrence included poor preoperative pain control (Barrow Neurological Institute score >IV) and multivessel compression. Furthermore, combined compression of the superior cerebellar artery and petrosal vein was associated with worse outcomes.
