Background: Cryptococcosis is the most common mycosis of the central nervous system. It may develop in immunocompetent and immunocompromised patients, the latter representing most cases. The most common presentation of the disease is meningitis, whereas intra-axial lesions in the form of cryptococcoma are less frequent with a greater tendency to present in immunocompetent patients. The presentation of pituitary cryptococcoma is exceptional. To the best of the authors' knowledge, there is only one case published in the medical literature., Observations: The authors present the case of a 30-year-old male without a relevant medical history. He was referred to our center with a pituitary mass on magnetic resonance imaging and panhypopituitarism. The patient underwent endonasal endoscopic transsphenoidal tumor resection, and a histopathological diagnosis of pituitary cryptococcoma was made. Medical management included fluconazole and intravenous amphotericin., Lessons: This case underscores the neurosurgical and medical management of an exceptional clinical presentation of pituitary cryptococcoma in an immunocompetent patient. To the best of the authors' knowledge, there is only one case published in the medical literature. This case provides an invaluable review of the clinical, imaging, and therapeutic considerations regarding this exceptional clinical entity.

The middle fossa, cavernous sinus, and paraclival triangles consist of ten triangles. Their use in a surgical approach is vast; most are used as landmarks to access and identify other structures of surgical interest. Multiple labels, borders, and contents mentioned by different authors make understanding and reproduction challenging and confusing. This study aims to organize and clarify recent or most relevant publications and disclose our portrayal of the ten triangles using cadaveric dissection and simple and practical figures. Four middle fossa triangles, four cavernous sinus triangles, and two paraclival triangles were dissected and delineated in a cadaveric specimen. Drawings were simplified to eliminate confusion and evaluate the triangles effortlessly. Similarities and differences in triangle names, border limits, and contents are described in a precise form. The recognition of triangle landmarks allows for treating pathologies in a frequently distorted anatomy or challenging to access structure. That is why an accurate knowledge of the surgical anatomy should be mastered, and a safe approach should be accomplished., (© 2023. The Author(s).)

Background: Focal cortical dysplasias (FCD) represent highly intrinsically epileptogenic lesions that require complete resection for seizure control. Resection of pure motor strip FCD can be challenging. Effective control of postoperative seizures is crucial and extending the boundaries of resection in an eloquent zone remains controversial., Observations: The authors report a 52-year-old right-handed male with refractory epilepsy. The seizure phenotype was a focal crisis with preserved awareness and a clonic motor onset of right-hemibody. Epilepsy surgery protocol demonstrated a left pure motor strip FCD and a full-awake resective procedure with motor brain mapping was performed. Further resection of surgical boundaries monitoring function along intraoperative motor tasks with no direct electrical stimulation corroborated by intraoperative-neuromonitorization was completed as the final part of the surgery. In the follow-up period of 3-years, the patient has an Engel-IB seizure-control with mild distal lower limb palsy and no gate compromise., Lessons: This report represents one of the few cases with pure motor strip FCD resection. In a scenario similar to this case, the authors consider that this variation can be useful to improve seizure control and the quality of life of these patients by extending the resection of a more extensive epileptogenic zone minimizing functional damage.
