Cubital tunnel syndrome (CuTS) is a prevalent but often under-recognized compressive neuropathy of the upper extremities, involving the entrapment of the ulnar nerve within the cubital tunnel at the elbow. CuTS is common, but remains relatively unfamiliar to many neurosurgeons compared to other neuropathies. It frequently presents with sensory disturbances and motor deficits in the hand, particularly affecting the ulnar digits, and it may be linked to specific usage patterns or even considered a form of neurotrauma. Its diagnosis typically involves a clinical assessment supplemented by imaging and electrophysiological studies to evaluate the extent of nerve involvement. While conservative management may be sufficient in the early stages, surgical intervention is often necessary for advanced cases, and various techniques offer differing outcomes. This review underscores the importance of a thorough anatomical understanding in guiding an accurate diagnosis and effective treatment, ultimately contributing to improved patient outcomes. These insights are essential for clinicians encountering the complexities of CuTS in diverse clinical scenarios.

Epithelioid hemangioendothelioma (EHE) is a rare benign vascular tumor, affecting fewer than one in a million individuals. Spinal EHE is exceptionally rare. This case report presents a case of recurrent spinal EHE, focusing on its clinical manifestation and providing a brief overview of its genetic characteristics. Seven years prior, a patient underwent subtotal resection of a lumbar and retroperitoneal EHE. Due to severe intraoperative bleeding, part of the lumbar spine mass was left unresected and subsequently treated with a moderate dose of radiation therapy. More recently, the patient presented with bilateral lower extremity weakness and urinary incontinence. Imaging studies revealed metastases in the thoracic and sacral bones, along with regrowth in the anterior portion of the previously treated spinal EHE. The patient underwent a series of operations to address both the regrowth and metastases, followed by intensity-modulated radiation therapy to target the remaining tumor tissue while minimizing damage to surrounding structures. Although EHE is generally considered benign, this indolent tumor has a tendency for persistent regrowth and metastasis. This case highlights the importance of radical resection and the potential role of higher radiation doses in preventing recurrence. Molecular testing may aid in achieving an accurate diagnosis and guiding effective treatment strategies.
