Xanthogranulomas are uncommon granulomatous entities, and xanthogranulomas occurring in the sellar region are extremely rare, with a limited number of cases reported in the literature. Diagnosis, management, and prognosis of sellar xanthogranulomas are poorly understood. ⋯ Sellar xanthogranuloma should be considered in the differential diagnosis of lesions in the sellar region. Some radiologic characteristics, including hyperintensity on T1-weighted imaging, heterogeneous hyperintensity on T2-weighted imaging, variable enhancement, and absence of calcification, can assist in making the preoperative diagnosis. Surgical outcomes are favorable.

Intracranial hypotension secondary to spontaneous spinal cerebrospinal fluid (CSF) fistula is a rare condition that can have serious sequelae. Early diagnosis and treatment can be challenging. ⋯ Spontaneous CSF leaks are a rare cause of postural headache. Although epidural blood patching is an easy and safe intervention, early serial imaging to ascertain the evolution of the pathology may identify cases that are amenable to early surgical management.

Our pilot study evaluated the effectiveness of our telementoring-telescripting model to facilitate seamless communication between surgeons while the operating surgeon is using a microscope. ⋯ Our pilot study showed a platform feasible in providing effective operative direction to inexperienced operators while operating using a microscope. A remote mentor was able to view the visual field of the microscope, annotate on the visual stream, and have the annotated stream appear in the binocular view for the operating mentee.
