Case Reports
Reversible severe brainstem herniation and obstructive hydrocephalus from cystoperitoneal shunt overdrainage.
We present a case of symptomatic intracranial hypotension secondary to CSF overdrainage from a cystoperitoneal shunt system. Brain MRI shows distortion of the midbrain with secondary occlusion of the cerebral aqueduct resulting in obstructive hydrocephalus. The symptoms, brainstem herniation, and hydrocephalus resolved after tie occlusion of the shunt.

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare syndrome characterized by the triad of cutaneous hemangiomas, venous varicosities, and osseous-soft tissue hypertrophy of the affected limb. Clinical manifestations, genetic testing, and radiologic imaging are the key steps in diagnosing this syndrome. ⋯ KTWS is a rare disease with a wide range of manifestations. Multisystemic evaluation of this group of patients should be performed to identify cavernous hemangiomas at the early stage of life and adequately treat them in the future. Treatment of KTWS patients with cavernous hemangiomas should not be different from the treatment of patients with any other hemangiomas, and surgical intervention should be considered on a case-to-case bases.

White matter injury (WMI) has been observed after experimental intracerebral hemorrhage (ICH). The supporting clinical data have been sparse. We assessed the presence, extent, and progression of WMI in patients with ICH. ⋯ WMI will progress over time in patients with ICH, and WMIP has been associated with worse outcomes. This novel finding could represent a potential therapeutic target. Future prospective larger studies are needed to confirm our findings.

Compression of the common fibular nerve at the level of the fibular neck is considered to be the most frequent lower limb entrapment syndrome, which can be either idiopathic or secondary. Decompressive surgery is indicated only after failure of conservative treatment and/or severe neurologic deficit. The effectiveness of microsurgical decompression has been established only for secondary entrapment syndrome. The aim of this study is to assess the results of microsurgical decompression and establish the prognosis of idiopathic severe common fibular nerve entrapment. ⋯ Microsurgical decompression should be considered early in the context of severe idiopathic common fibular nerve entrapment in order to get a favorable outcome.

Preoperative endovascular embolization of hypervascular metastatic spine tumors can reduce intraoperative blood loss. One frequent objection to embolizing these tumors is the concern for associated arteries feeding the spinal cord, such as the artery of Adamkiewicz. This study aimed to elucidate a relationship between spinal levels affected by hypervascular spine metastases and associated radiculomedullary arteries (RMAs). ⋯ In this study, no association was found between spinal levels affected by hypervascular metastatic spine tumors and RMAs feeding the spinal cord by diagnostic spinal angiography. This suggests that these tumors have little intrinsic affinity for spinal levels with an RMA. However, given that tumor embolization frequently requires accessing multiple levels, the risk of encountering an RMA during embolization remains significant.
