30 Couldwell, William T.Normal dimensions of the posterior pituitary bright spot on magnetic resonance imaging: Clinical articleObject. The normal pituitary bright spot seen on unenhanced T1-weighted MRI is thought to result from the T1-shortening effect of the vasopressin stored in the posterior pituitary.

35 Kestle, John R. W.Abdominal bindersSklar and colleagues2 describe their experience managing "over-shunting headaches" with an abdominal binder. Seventy children with over-shunting headaches complied with application of a binder for about 1 month. In 61 patients (87%), the headaches "greatly improved or went away." This headache relie...2012-01-01

38 Schmidt, Meic H.Spinal extradural arachnoid cysts: clinical, radiological, and surgical featuresExtradural arachnoid cysts in the spine are rare and are seldom a cause of spinal cord compression. They are thought to arise from congenital defects in the dura mater, and they almost always communicate with the intrathecal subarachnoid space through a small defect in the dura. The mainstay of trea...Spinal extradural arachnoid cyst; Spinal meningeal cyst; Neurogenic claudication2007
39 Schmidt, Meic H.Minimally invasive thoracoscopic resection of paraspinal neurogenic tumors: technical case reportOBJECTIVE: The posterior mediastinum is a common location for benign neurogenic tumors. They are frequently asymptomatic but can present with local compressive or neurological symptoms. METHODS: Thoracoscopy is used increasingly over posterolateral thoracotomy for the removal of these lesions. RES...2008-01-01
40 Couldwell, William T.; Schmidt, Richard H.Ruptured intracranial dermoid cysts: clinical, radiographic, and surgical featuresIntracranial dermoid cysts are pathologically characterized by a thick, stratified squamous epithelium cyst wall containing dermal elements. Rupture into the subarachnoid spaces and ventricles is extremely rare. We review the clinical, radiographic, and surgical features of eight ruptured dermoid c...Dermoid cyst; Intracranial; Rupture; Tumor2008
