Untreated Giant Macroprolactinoma with Chronic Cerebrospinal Fluid Leakage: An Unusual Complication.

Case Rep Endocrinol 2019 15;2019:4825357. Epub 2019 Jan 15.

Regenerative Medicine Cluster, Advanced Medical and Dental Institute, Universiti Sains Malaysia, Bertam, 13200 Kepala Batas, Pulau Pinang, Malaysia.

Macroprolactinoma has the potential to cause base of skull erosion and often extends into the sphenoid sinus. Rapid shrinkage of this invasive tumor following dopamine agonist therapy has been postulated to cause unplugging of the eroded area, leading to cerebrospinal fluid leakage. To the best of our knowledge, the occurrence of spontaneous cerebrospinal fluid leak in treatment-naive prolactinomas is very rare, the majority of which involve undiagnosed macroprolactinomas.

Do Most Patients With a Spontaneous Cerebrospinal Fluid Leak Have Idiopathic Intracranial Hypertension?

J Neuroophthalmol 2019 Feb 8. Epub 2019 Feb 8.

Departments of Ophthalmology (SB, NJN, and VB), Otolaryngology-Head and Neck Surgery (JML), Radiology and Imaging Sciences (AMS), Neurological Surgery (NMO and NJN), and Neurology (NJN and VB), Emory University School of Medicine, Atlanta, Georgia.

Background: The association between cerebrospinal fluid (CSF) leaks at the skull base and raised intracranial pressure (ICP) has been reported since the 1960s. It has been suggested that spontaneous CSF leaks might represent a variant of idiopathic intracranial hypertension (IIH). We review the evidence regarding the association between spontaneous CSF leaks and IIH, and the role of ICP in the pathophysiology of nontraumatic skull base defects. Read More

Spontaneous Intracranial Hypotension: Imaging in Diagnosis and Treatment.

Radiol Clin North Am 2019 Mar 7;57(2):439-451. Epub 2018 Dec 7.

Department of Radiology, Duke University Medical Center, Box 3808, Durham, NC 27710, USA.

This article reviews the role of imaging in the diagnosis, management, and treatment of spontaneous intracranial hypotension (SIH). SIH is a debilitating and often misdiagnosed condition caused by either a spinal cerebrospinal fluid (CSF) leak or a CSF to venous fistula. This pathologic condition is identified and localized via spinal imaging, including computed tomographic (CT) myelography, dynamic myelography, dynamic (ultrafast) CT myelography, MR imaging, or MR myelography with intrathecal gadolinium.

A modern series of subdiaphragmatic craniopharyngiomas.

J Neurosurg 2018 Oct 1:1-6. Epub 2018 Oct 1.

6Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts.

OBJECTIVEThe endoscopic endonasal approach has been proposed as a primary surgical strategy for select craniopharyngiomas. However, those tumors that arise from the sella have not been classified with the other craniopharyngioma subtypes in terms of surgical nuances, intraoperative findings, and postoperative outcomes. The authors describe their experience with a select subtype of craniopharyngioma arising within the sella subjacent to the diaphragma sellae and refer to these tumors as type 0. Read More

Oropharyngeal CSF Leak Secondary to Anterior Cervical Discectomy and Fusion.

Case Rep Otolaryngol 2018 31;2018:7629184. Epub 2018 Jul 31.

Department of Otolaryngology Head Neck Surgery, University of Texas Health at San Antonio, 7703 Floyd Curl Dr, MC 7777, San Antonio, TX 78229, USA.

We present a case of an oropharyngeal cerebrospinal fluid (CSF) fistula in a patient that presented with headache, rhinorrhea, and pneumocephalus years after an anterior cervical discectomy and fusion. Imaging suggested a defect in the fovea ethmoidalis, but endoscopic surgery revealed the defect in the oropharynx. A second procedure was performed to remove the spinal hardware and repair the leak.

Endoscopic Transnasal Transclival Approach to a Pontine Cavernoma with Associated Developmental Venous Anomaly.

World Neurosurg 2018 Oct 18;118:212-218. Epub 2018 Jul 18.

Department of Neurological Surgery, George Washington University, Washington, DC, USA.

Background: Brainstem cavernous malformations represent around 8%-22% of all intracranial cavernous malformations but exhibit a higher annual incidence of hemorrhage (2%-3%) compared with other cavernous angiomas and tend to be more symptomatic given their proximity to critical nuclei and fiber tracts. Recently, endoscopic endonasal techniques have been used for the removal of ventral skull base lesions, with significant improvement in operative morbidity and mortality compared with open approaches. Here we demonstrate the utility and feasibility of the endoscopic transclival approach for ventrally located pontine cavernomas in carefully selected patients. Read More
