Abstract

Leiomyomas are benign smooth-muscle tumors that are common in the alimentary tract, uterus, skin, and subcutaneous tissue. They are very uncommon in the upper respiratory tract and rare in the nasal cavity and paranasal sinuses. To the best of our knowledge, only 23 such cases have heretofore been published in the literature. We report 2 new cases of sinonasal leiomyoma that originated at different sites in the nasal cavity. We also discuss the various investigative and therapeutic modalities available.

Does Helicobacter pylori play a role in upper respiratory tract inflammation? A case report

Abstract
Persistent isolated inflammation of the sphenoid sinus, an entity that is not diagnosed very often, poses a challenge to clinicians and researchers alike. Its features tend to suggest that its etiopathogenesis is different from that of more common forms of chronic rhinosinusitis. We report the case of a 54-year-old woman who had a history of distressing chronic postnasal drip and a globus sensation with opacification of the sphenoid sinus. She was diagnosed with gastroesophageal reflux, and Helicobacter pylori was detected in her gastric contents and in the inflamed mucosa of the sphenoid sinus, as well. Complete symptom relief was achieved only after she had undergone surgical sphenoidotomy and treatment with anti'H pylori medication. We discuss the potential for this ubiquitous gastric bacterium to play a role in at least some forms of chronic sinonasal inflammation.

December 1, 2004     Ahmet Kemal Firat, MD; Yezdan Firat, MD
article
Abstract
Lateral intrasphenoidal encephaloceles are rare anomalies. We describe a unique case in which spontaneous bilateral intrasphenoidal lateral encephaloceles were discovered in a 53-year-old man during a work-up for cerebrospinal fluid leak. We discuss our clinical findings and the results of preoperative computed tomography and magnetic resonance imaging.
