Radiation-induced brachial plexus neuropathy (RIBPN) is an uncommon problem. It is a delayed nontraumatic brachial plexus neuropathy following radiation treatment for carcinomas in the region of neck, axilla, and chest wall. The incidence is more commonly reported following radiation treatment for carcinoma of breast. ⋯ The management options are limited, and external neurolysis of the involved brachial plexus with excision of the perineural scar tissue is recommended in patients with severe clinical manifestations. We review our experience in the management of RIBPN from 2004 to 2017 and highlight the features of the 11 patients with this disorder whom we encountered during this period. The relevant clinical findings, natural history, pathophysiology, radiological characteristics, and various management options are briefly discussed.

Perilesional gliosis is an important substrate for seizures in patients harboring a calcified neurocysticercosis (NCC) lesion and magnetic resonance imaging (MRI) is useful for evaluating gliosis. ⋯ Combining 3D-DIR with 3D-FLAIR, and postcontrast 3D-T1W sequences is beneficial for evaluation of calcified NCC lesions and 3D-DIR sequence is better than other two sequences for perilesional signal abnormalities.

Results of and the complications encountered during surgery for very large and giant intracranial aneurysms are illustrated. ⋯ In this large series of very large and giant aneurysms treated with microsurgical clipping and bypasses, excellent results were obtained in the long term, in regards to aneurysm occlusion, functional status, and graft patency. Our experience will be very useful to other neurosurgeons who treat these complex lesions.

Randomized Controlled Trial Comparative Study
Comparison of normal saline and balanced crystalloid (plasmalyte) in patients undergoing elective craniotomy for supratentorial brain tumors: A randomized controlled trial.
The choice of fluid is important in neurosurgical patients, who may be dehydrated due to the administration of diuretics in order to reduce cerebral edema. Normal saline, the infused fluid routinely used in neurosurgical patients, can cause hyperchloremic metabolic acidosis. A balanced crystalloid (BC) may help to maintain the metabolic status more favorably in these patients, without adversely affecting brain relaxation. ⋯ The balanced crystalloid maintains metabolic status more favorably than normal saline in neurosurgical patients. Hyperchloremic metabolic acidosis, and the other problems which occur as a consequence of normal saline infusion may be circumvented by choosing a balanced crystalloid electrolyte solution. Neither of the crystalloids appeared to have any adverse effect on brain relaxation.

The 2016 central nervous system (CNS) World Health Organisation (WHO) Update has merged the entities of meningeal solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) into a single entity based on the presence of the nerve growth factor 1A (NGFI-A) binding protein 2 (NAB2)- signal transducer and activator of transcription 6 (STAT6) gene fusion in these tumors. Immunohistochemical (IHC) staining with STAT6 results in a strong nuclear positivity confirming the diagnosis. Meningeal SFT/HPCs are currently histologically graded according to a three-tiered system. Grade I (SFT phenotype) is benign, whereas grades II and III (HPC phenotype) are malignant and require radiotherapy in addition to gross total resection. ⋯ These rare tumors need to be accurately diagnosed and optimally treated (gross total resection and radiotherapy) to improve the prognosis.
