Endoscopic vs. Open Microsurgical Excision of Colloid Cysts: A Comparative Analysis and State-of-the-Art Review of Neurosurgical Techniques.
The surgical approaches of colloid cysts commonly include endoscopy or open microsurgery. Each approach carries its own challenges, feasibility, and complications. The aim of the current study is to compare endoscopic versus open microsurgical excision of third ventricular colloid cysts. ⋯ Both endoscopic and microsurgical approaches provide favorable surgical outcomes in colloid cyst resection. The complication rates between both approaches is statistically insignificant. The optimal surgical approach for colloid cyst resection remains controversial.

Gastric stromal tumor is a potentially malignant mesenchymal tumor that is difficult to diagnose before surgery. Computed tomography is the most commonly used tool for diagnosing gastrointestinal stromal tumor. This study combined peripheral nerve analysis and computed tomography for diagnosis and prognosis of gastrointestinal stromal tumor. This study shows that computed tomography can accurately show the location, shape, and size of gastric scrotal tumors and has important clinical value in identifying benign and malignant tumors as well as early clinical judgment and treatment and prognosis.

The pathogenesis and clinical characteristics of sciatica caused by pregnancy were summarized to reduce the incidence of misdiagnoses and missed diagnoses. The sciatic nerve, tibial nerve, common peroneal nerve, sural nerve, superficial peroneal nerve, saphenous nerve, and lateral femoral cutaneous nerve were examined using ultrasonography for 7 imaging features, including the shape and internal structure of the peripheral nerves of the lower extremities. ⋯ We found no significant differences in the peripheral nerve cross-sectional area between the left and right legs but did find a positive correlation with body mass index and age.

Vertebral artery dissections (VADs) are a rare cause of ischemic stroke that can occasionally lead to intracranial hemorrhage (ICH). This study aims to identify differences in predisposing factors, event characteristics, and outcomes between patients with only a VAD and patients with VAD and concomitant ICH. ⋯ Patients who experienced an ICH in addition to a VAD did not have any identifiable risk factors. Cervical spine fractures were more common in patients with VAD and ICH. VAD patients with a concomitant ICH have worse neurologic outcomes than patients with only a VAD.

Internal carotid artery (ICA) stenosis rarely occurs in pituitary apoplexy. Little is known of the causes of this condition. The present study investigated the factors related to ICA stenosis associated with pituitary apoplexy. ⋯ Our study revealed that age, tumor size, and sphenoid sinus mucosal thickening were strongly related to the occurrence of ICA stenosis in pituitary apoplexy. Among these factors, age had the potential of being an independent predictor of the condition.
