Preoperative Endovascular Embolization of Glomus Jugulare Tumors: A Retrospective Case Series of 22 Embolizations in 20 Patients and Literature Review

Arq. bras. neurocir; 41 (1), 2022
Objective Glomus jugulare tumors, or tympanojugular paragangliomas, are rare, highly vascularized skull base tumors originated from paraganglion cells of the neural crest. With nonabsorbable embolic agents, embolization combined with surgery has become the norm. The authors assess the profile and outcome...

Introduction The purpose of this study was to define the anatomical relationships of the pterygopalatine fossa (PPF) and its operative implications in skull base surgical approaches. Methods Ten cadaveric heads were dissected at the Dianne and M Gazi Yasargil Educational Center MicrosurgicaLaboratory, in...

Jugular Foramen’s Paraganglioma in a Patient with Von Hippel-Lindau Disease: Case Report

Arq. bras. neurocir; 40 (2), 2021
Glomus jugular tumors, also known as paragangliomas (PGLs), are rare and related to several clinical syndromes described. These are located in the carotid body, the jugular glomus, the tympanic glomus and the vagal glomus. The symptoms are directly related to the site of involvement and infiltration. The...

5-aminolevulinic Acid and Surgical Margin Analysis in Calvarial Metastasis with Pericranium or Dural Extension: Technical Note

Arq. bras. neurocir; 39 (3), 2020
Metastasis to the calvarium with direct pericranium or dural infiltration may be treated with radical surgical removal in selected cases. We describe microsurgical resection of calvarial metastases with fluorescence-guided technique using 5-aminolevulinic acid (5-ALA) in two female patients with breast c...

Endoscopic endonasal double flap technique for reconstruction of large anterior skull base defects: technical note

Abstract Introduction: One of the main concerns in endoscopic endonasal approaches to the skull base has been the high incidence and morbidity associated with cerebrospinal fluid leaks. The introduction and routine use of vascularized flaps allowed a marked decrease in this complication followed by a gr...

Olfactory Groove Schwannoma — A Case Report and Literature Review

Arq. bras. neurocir; 37 (3), 2018
Olfactory groove schwannomas (OGSs) are rare benign tumors of the anterior skull base region. Considering the lack of Schwann cells in the optic and olfactory nerves, their origin remains enigmatic. Despite the precursor cell, total resection of the lesion is curative, as long as the histopathological fe...

Presentamos el caso de una mujer de 13 años con un gran tumor de características óseas en la fosa infratemporal derecha, el cual fue biopsiado mediante un abordaje endoscópico transeptal transpterigoídeo. La biospia mostró un osteocondroma. Describimos el caso y discutimos sus aspectos relevantes....

Evaluación del olfato en pacientes con patología tumoral en la región selar, intervenidos mediante abordaje endoscópico transesfenoidal transnasal

Introducción: Para acceder a la región selar, podemos utilizar las técnicas transcraneal, transeptal, o transnasal endoscópica, pudiendo provocar diferentes grados de hiposmia. Se ha descrito menor morbilidad al utilizar la técnica endoscópica, pero faltan estudios dirigidos a los resultados olfato...
