OBJECTIVES Sellar reconstruction with intrasellar packing following endoscopic resection of pituitary macroadenomas remains a subject of clinical and radiological discussion particularly, when an intraoperative cerebrospinal fluid (CSF) leakage is absent. This study was conducted to contribute our experience with sellar reconstruction after a standard endoscopic surgery of pituitary macroadenom...

The authors present the case of a 55-year-old man suffering from intractable spontaneous intracranial hypotension, in whom conservative treatment with 19 weeks of bed rest was not effective. In this period the patient twice underwent surgery for bilateral chronic subdural hematoma, a complication of spontaneous intracranial hypotension. Conventional radionuclide cisternography, magnetic resonan...

Watertight dural closure is imperative after neurosurgical procedures, because inadequately treated leakage of cerebrospinal fluid (CSF) can have serious consequences. We used a rat durotomy model to test the usefulness of a new gelatin glue as a dural sealant in a rat model of transdural CSF leakage. All rats were randomly divided into one of the following three treatment groups: no applicatio...

BACKGROUND AND PURPOSE Radiologic identification of the location of the CSF leakage is important for proper surgical planning and increases the chance of dural repair. This article describes our experience in analyzing clinically suspected cranial CSF fistulas by using MR imaging combined with the intrathecal administration of a gadolinium-based contrast agent. MATERIALS AND METHODS A total o...

UNLABELLED Radionuclide cisternography is an indispensable examination to detect cerebrospinal fluid (CSF) leakage in patients suspected of having spontaneous intracranial hypotension (SIH). However, it sometimes fails to demonstrate the site of CSF leakage, and in such cases, early bladder visualization is utilized for the diagnosis of SIH as an indirect finding. The aim of this work is to imp...

background developing controlled hypercarbia is a known scheme of lowering the suprasellar part of the adenoma in order to assist the surgeon, which acts through raising the icp and therefore the csf pressure. objectives the purpose of this study is to compare the effect of introducing a lumbar drain with that of controlled hypercapnia on the quality of transsphenoidal pituitary tumor resection...

The transoral approach is a direct route to the clivus. However, application of this approach is infrequent because of the risk of cerebrospinal fluid (CSF) fistula and subsequent meningitis. We report a case of clival metastatic tumor treated by staged operation without CSF leakage. A 39-year-old man was found to have a tumor in clivus extending to the intradural space. Two-staged resection th...

Cerebrospinal fluid (CSF) rhinorrhea is often intermittent, thus complicating the cisternographic localization of the leakage. In four patients studied, this difficulty was overcome by lumbar infusion of artificial CSF to which a bolus of radionuclide was added. The tracer was moved in bulk to the basal cisterns, and the rise in CSF pressure elicited a profuse rhinorrhea. Sequential imaging was...

We report a case of diffuse enhancement of the cerebrospinal fluid (CSF) after intravenous administration of gadopentetate dimeglumine in an 8-year-old girl with a primitive neuroectodermal tumor. The enhancement of the CSF was caused by leakage of gadolinium chelate complexes into the CSF, which was proved by CSF analysis.

Uncontrolled cerebrospinal fluid (CSF) leakage after transsphenoidal surgery (TSS) for pituitary adenoma can lead to meningitis. Intracranial mycotic pseudoaneurysm is a rare complication in central nervous system infection. Large single pseudoaneurysm is more uncommon. Most mycotic aneurysms occur due to endocarditis. The present patient had no heart problem and was infected by CSF leakage aft...
