Recurrence of cerebrospinal fluid-venous fistulas at different spinal levels following transvenous embolisation or blood/fibrin glue patching.

Aim Of The Study: This study presents cases of recurrent cerebrospinal fluid-venous fistulas (CVFs) de novo at a different spinal level following successful treatment of initial CVFs. The aim was to highlight this rarely described phenomenon and report the clinical and imaging features after initial treatment, providing insights into the dynamics of recurrent CVFs.

Clinical Rationale For The Study: Understanding the course of CVFs post-treatment is crucial for optimising patient management, especially when symptoms persist or recur.

Clival ectopic pituitary prolactinoma was successfully managed by transsphenoidal surgery: A rare case report.

Key Clinical Message: Ectopic pituitary adenoma is a rare neoplasm located in the clivus and could mimic other clival tumors. Diagnosis and treatment could be challenging. It should be considered in the differential diagnosis of clival tumors.
