This technique is widely applied in neurosurgical and otorhinolaryngological practice for the management of pituitary lesions, sellar and parasellar pathologies, sphenoid sinus tumors, cavernous sinus lesions, and tumors of the nasal cavity and nasopharynx, offering improved surgical access and patient comfort. Endoscopic procedures may be associated with serious complications, including intracranial hemorrhage, pneumocephalus, cerebrospinal fluid (CSF) leakage, infection, and cranial nerve injury, which can occur in both early and late postoperative periods. We report a patient who developed early postoperative pneumocephalus, intracerebral hemorrhage, and CSF leakage following endoscopic endonasal biopsy of a lesion adjacent to the mid-cranial base. Based on clinical and radiological findings, the lesion was initially suspected to represent nasopharyngeal carcinoma. Therefore, the patient underwent an endoscopic endonasal biopsy rather than gross total resection. Histopathological and immunohistochemical analyses subsequently established the diagnosis of meningioma. Two weeks postoperatively, the patient developed CSF leakage, pneumocephalus, and intracerebral hemorrhage, and the skull base defect was repaired via an EEA. Subsequently, the patient developed hydrocephalus in the mid-to-late postoperative period, which was successfully treated with ventriculoperitoneal shunt placement, resulting in complete clinical recovery. This case highlights the need for close clinical and radiological follow-up not only in the early period but also in the mid-to-late postoperative periods. Furthermore, radiological findings suggestive of malignancy may be inconsistent with immunohistochemical results; this underscores the critical role of immunohistochemical examination in determining definitive diagnosis and prognosis.</p>","PeriodicalId":72274,"journal":{"name":"Archive of clinical cases","volume":"13 1","pages":"5-10"},"PeriodicalIF":0.6,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13142664/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147846825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 78-year-old woman with end-stage renal disease (ESRD) on continuous ambulatory peritoneal dialysis (CAPD) presented with a one-week history of clear per vaginal leakage. This episode developed following an initial presentation of PD peritonitis for which she was receiving antibiotic therapy. She reported the onset of clear vaginal leakage during a routine clinic visit for monitoring of her vancomycin level, prompting her admission for further evaluation. On clinical examination, the patient was afebrile and hemodynamically stable. Abdominal examination was satisfactory, however, speculum examination showed pooling of clear fluid in the vagina without evidence of vaginal or cervical pathology. Subsequent CT peritoneography demonstrated contrast-filled dialysate tracking from the peritoneal cavity, passing through bilaterally patent fallopian tubes into both the endometrial and vaginal cavities. Interestingly, there was no evidence of vaginal wall perforation or an abnormal fistulous connection identified. Given the absence of a correctable fistulous tract, PD was discontinued and the patient was transitioned to hemodialysis, resulting in complete resolution of symptoms. Although rare, physiological tubal patency can provide a conduit for dialysate leakage in PD patients, particularly following recent peritonitis. This mechanism is especially uncommon in post-menopausal women, highlighting the novelty of this case.
