A sellar spine is a rare midline osseous spur, which arises from the dorsum sellae and projects into the pituitary fossa. It can be found incidentally on imaging or may present with symptoms related to optic chiasm compression or hormonal disturbances.Herein, we present the case of an incidentally detected sellar spine in a patient presenting with sudden onset headaches.

Background: Cerebrospinal fluid (CSF) leakage frequently complicates endoscopic endonasal transsphenoidal pituitary resections, despite the use of lumbar drains, nasoseptal flaps, or commercial dura sealants. Managing this complication often requires revision surgery and increases the risk of infection. Platelet-rich fibrin (PRF), an affordable autologous biomaterial derived from the patient's blood through short, angulated centrifugation, contains growth factors and leukocytes embedded in a fibrin matrix.

Article Synopsis
- Atypical teratoid/rhabdoid tumor (AT/RT) is a rare brain cancer mainly found in children, but can appear in adults, especially in the sellar region of middle-aged women.
- A case study is presented of a 51-year-old woman with AT/RT who had headaches and left ptosis, leading to a diagnosis and treatment that included surgery, radiation, and chemotherapy.
- Despite treatment, the patient developed lung metastases and passed away seven months post-diagnosis, highlighting the need for further awareness of AT/RT in adults, particularly when considering sellar masses.

Article Synopsis
- This study investigates the effectiveness of Diffusion-Weighted Imaging (DWI) in improving the identification of sellar and parasellar tumors during routine pituitary MRI scans, recognizing a gap in current guidelines.
- A retrospective analysis of 242 MRI scans revealed that invasive pituitary adenomas had significantly lower apparent diffusion coefficient (ADC) values compared to other tumor types, with specific cut-off points indicating high sensitivity and specificity for differentiation.
- The findings suggest that incorporating DWI into standard MRI protocols can significantly enhance diagnostic accuracy for these tumors, with a quick scan time making it a practical addition to pituitary examinations.
