Dural Venous Sinus Thrombosis after Vestibular Schwannoma Surgery: The Anticoagulation Dilemma.

 Dural venous sinus thrombosis (DVST) is a relatively understudied complication of vestibular schwannoma (VS) surgery. Several studies have examined this topic; however, there is limited data on the incidence, clinical progression, and proper management of this patient population.  A retrospective review was performed for patients undergoing surgery for VS at a single institution.

Combined Transarterial and Transvenous Onyx Embolization of Jugular Foramen Paragangliomas.

Objective: Jugular foramen paragangliomas are highly vascular tumors known to have significant venous hemorrhage during resection even after conventional transarterial embolization. The authors report a novel technique to the endovascular embolization of jugular foramen paragangliomas using a combined transarterial and transvenous access for better intraoperative control of blood loss and visualization.

Methods: This is a retrospective data collection of 2 patients diagnosed with jugular foramen paragangliomas with novel embolization technique and surgical resection.

Neurosarcoidosis Presenting as Isolated Bilateral Cerebellopontine Angle Tumors: Case Report and Review of the Literature.

Objectives: To describe a unique case of isolated bilateral sarcoidosis of the cerebellopontine angle as well as the related imaging in the case. To conduct a literature review of the published articles regarding sarcoidosis of the cerebellopontine angle.

Data Sources: Representative case report from a single institution as well as PubMed and Scopus database searches.

Light Chain Amyloidosis Presenting as Bilateral External Auditory Canal Obstructing Masses.

: A morbidly-obese 57-year-old diabetic and hypertensive man with chronic kidney disease, diastolic heart failure, and bilateral hearing loss was found to have soft tissue masses/densities in the lateral aspect of both auditory canals on local examination and on imaging. He underwent biopsies of both ear canal masses and histologic examination revealed amyloid deposits in the dermis. These deposits were confirmed as AL (amyloid light chain) kappa-type amyloid by laser mass spectrometry.

Cochlear implantation in the presence of a programmable ventriculoperitoneal shunt.

Objective: Document challenges of cochlear implantation in the presence of a ventriculoperitoneal shunt (VPS) with a programmable valve.

Patient: A 7-month-old, postmeningitic, hydrocephalic infant with profound sensorineural hearing loss.

Intervention: Ventriculoperitoneal shunt revision with a nonprogrammable valve and bilateral cochlear implantation.
