Fungi in paranasal sinuses are characteristic and considered a major pathogenic factor in a subset of chronic rhinosinusitis (CRS) patients, known as allergic fungal rhinosinusitis (AFRS). CD8(+) T cells are enriched in AFRS sinuses but their role in fungal-specific responses is unknown. Alternaria alternata- and Aspergillus fumigatus-specific T lymphocyte responses were investigated in 6 AFRS ...
Imaging of sinonasal pathology may occur for assessment of rhinosinusitis or mass lesions. Rhinosinusitis is prevalent in up to 16% of the US population with annual economic burdens estimated at 22 billion dollars. Rhinosinusitis is characterized as acute or chronic based on symptom duration; if four or more episodes occur annually, the term recurrent acute rhinosinusitis (RARS) is used. In acu...
Objective. To determine the efficacy of sinonasal evaluation preceding hematopoietic cell transplant (HCT) and to correlate pretransplant findings with subsequent risk of post-HCT complications based on radiographic, endoscopic, and microbiologic findings. Study Design. Case series with chart review. Setting. Academic tertiary care center. Subjects and Methods. Seventy-one patients underwent pr...
Allergic mucin is described as thick, peanut butter-like mucus impacted in the paranasal sinuses of patients with allergic fungal rhinosinusitis. The presence of allergic mucin in the middle ear has never been reported. We encountered a 65-year-old female with allergic mucin found impacted in her left middle ear and mastoid cavity during revised tympanoplasty surgery at our institute. Bilateral...
Hyperprolactinemia is a rare entity in the pediatric population. The most common causes of hyperprolactinemia include drug use, hypothyroidism and renal insufficiency, though rarely a pituitary or sellar mass is discovered. We present an immunocompetent pediatric patient who presented with gynecomastia and was found to have hyperprolactinemia. Imaging showed a sphenoid mass and referral was mad...
The aim of this study was to evaluate the histopathological findings of unilateral paranasal sinus disease dominated by maxillary sinus opacification on routine non-contrast enhanced paranasal sinus CT. We performed a retrospective analysis of routine paranasal sinus CT conducted between March 2003 and April 2007. Unilateral maxillary sinus opacification (with or without ipsilateral ethmoid or ...
The complex regional anatomy of the nose and paranasal sinuses makes the interpretation of imaging studies of these structures intimidating to many radiologists. This paper aims to provide a key to interpretation by presenting a simplified approach to the functional anatomy of the paranasal sinuses and their most common (and most relevant) variants. This knowledge is basic for the full understa...
