Review Case Reports
Spinal arachnoid cyst associated with arachnoiditis following subarachnoid haemorrhage in adult patients: A case report and literature review.
Arachnoiditis is an inflammatory process resulting with the fibrosis of arachnoid mater. It can vary in severity from mild thickenings to catastrophic adhesions that ruins subarachnoid space. As a result, arachnoid cysts can be formed. Arachnoid cyst induced by symptomatic spinal arachnoiditis is a rare complication of subarachnoid haemorrhages. In this article, we aimed to present a case of spinal arachnoid cyst formation following subarachnoid haemorrhage and examine similar cases in the literature. ⋯ Subarachnoiditis and associated arachnoid cyst can cause severe morbidity. This rare situation (which especially occurs following subarachnoid haemorrhage of posterior fossa) should be known and physicians should keep in mind that it requires urgent surgical procedure.

Ectopic recurrence of craniopharyngioma is extremely rare following transcranial procedures of primary tumour. Here we describe 3 new cases of ectopic recurrence along the surgical route after transcranial gross total resection of primary tumour. ⋯ All ectopic tumours were safely resected via repeated craniotomy. Long-term surveillance of patients with resected craniopharyngioma is essential.

The surgical management of the craniocervical junction is challenging. Rigid posterior fixation of occiput/C1-C2 can be performed using a variety of surgical techniques including C2 pedicle/pars interarticularis, transarticular and intralaminar screw fixations. ⋯ Intra-laminar screw fixation is a safe alternative to transarticular and transpedicular/pars interarticularis fixation of C2 with advantage of having no risk of injury to vertebral artery and comparable biomechanical and pull-out strength.

Society of British Neurological Surgeons (SBNS) meetings are important national events which allow for the presentation of current academic work. The publication rate of presented abstracts is considered a proxy marker of the scientific strength of a conference. We aimed to determine the publication fate of presented abstracts at SBNS meetings over a 5-year period. ⋯ SBNS conferences have a respectable publication rate. Those abstracts that are published in full have gone on to gain a considerable number of citations reflecting their scientific relevance. However, studies presented at SBNS are susceptible to positive outcome bias.

Review Case Reports
Primary sellar melanocytic tumor mimicking hemorrhagic pituitary macroadenoma: Case report and literature review.
Primary melanocytic tumors of the central nervous system (CNS) are rare lesions, but primary sellar tumors are rarer. Only 10 cases have been reported, and they are often misdiagnosed as pituitary macroadenoma. We report the case of a 54-year-old Chinese man who developed progressive bitemporal hemianopsia and visual loss. ⋯ Once this type of lesion is suspected, the transfrontal approach may achieve preferable exposure and resection. Complete surgical resection may be sufficient for relatively benign lesions; otherwise, stereotactic fractionated radiotherapy is indicated. More cases should be reported to improve the treatment strategy.
