Myelocystocele Mimicking Myelomeningocele: A Case Report and Review of the Literature.
Myelocystoceles, which are classified as closed neural tube defects, are usually covered by skin and rarely complicated by hydrocephalus. We encountered an unusual case of a terminal myelocystocele with hydrocephalus with clinical characteristics of a myelomeningocele. ⋯ Presence of skin abnormalities, hydrocephalus, and lumbosacral mass strongly suggests a diagnosis of myelomeningocele. However, such cases should be differentiated from myelocystocele, especially when associated with severe hydrocephalus.

Clinically Silent ACTH-Positive Crooke Cell Adenoma: Case Report and Review.
Pituitary adenomas are one of the most common tumors of adulthood; however, subtypes such as Crooke cell adenoma are relatively rare. ⋯ Clinically silent Crooke cell adenomas are rare occurrences, and as such we report this case with investigation of past cases.

Percutaneous endoscopic lumbar diskectomy (PELD) has evolved over the last decades and has become an effective treatment for soft disk herniations. However, while its use increases, newer complications have been discovered. ⋯ PELD combined with foraminotomy is a relatively new and skill-demanding surgery which is indicated only in cases where foraminal disk herniation is combined with foraminal stenosis. This surgical strategy requires experience by the endoscopic surgeon to prevent procedure-related complications. Although rare, these complications can lead to increased morbidity.

Hemodynamics in a Middle Cerebral Artery Aneurysm prior to its Growth and Fatal Rupture: a Case Study and a Review of the Literature.
Hemodynamics plays an important role in the natural history of intracranial aneurysms. However, it is difficult to obtain longitudinal aneurysm image data. In this study, we had a rare chance to follow the process of growth and rupture of a middle cerebral artery (MCA) aneurysm. The aim of this study was to investigate the role of hemodynamics for growth and rupture in this particular aneurysm patient. ⋯ This case suggests that aneurysm rupture might be associated with low WSS and high OSI, whereas aneurysm growth may be related to high WSS in this particular individual MCA aneurysm patient.

It is not clear whether cognitive adverse events can occur after subthalamic nuclei deep brain stimulation in Parkinson disease, and the putative mechanisms are poorly understood. ⋯ In patients seen in routine clinical practice, the simultaneous presence of several neurodegenerative diseases might not be uncommon. The assessment of mild cognitive impairment with a standardized method is highly recommended, a systematic 3-dimensional volumetric analysis of hippocampal structures should be part of the pre-deep brain stimulation evaluation, and cerebrospinal fluid biomarkers should be screened for if at least 1 of the 2 previously mentioned aspects is abnormal.
