Introduction: A spontaneous pseudomeningocele (PMC) (e.g.without previous surgery or injury) is a rare pathology that may be mimicked as an unilateral polypoid mass in endoscopy or as a mucocele on CT /MRI, which only very exceptionaly doesn’t present with rhinoliquorhea. PMC develops when cerebrospinal fluid (CSF) becomes trapped behind the paranasal sinus mucosa or extracranial soft tissues, ...

BACKGROUND False-positive radioiodine (RAI) uptake related to chronic sinusitis and mucocele has only rarely been reported in patients with differentiated thyroid cancer (DTC) even with the recent use of single photon emission tomography with computed tomography (SPECT/CT) acquisition. No other etiology of sinus RAI uptake has been mentioned to date. OBJECTIVES We report five cases of DTC pat...

INTRODUCTION Mucoceles are slow-growing, benign lesions found in the paranasal sinuses that are locally destructive, causing bony resorption an displacement of adjacent structures. We present our experience in the surgical treatment of these lesions. METHODS This was a retrospective review of 58 paranasal sinus mucoceles in 54 patients between 1989 and 2012. We describe patient age and sex, m...

BACKGROUND Visual disturbances associated with isolated sphenoid sinus inflammatory diseases (ISSIDs) are easily misdiagnosed due to the nonspecific symptoms and undetectable anatomical location. The main objective of this retrospective case series is to investigate the clinical features of visual disturbances secondary to ISSIDs. METHODS Clinical data of 23 patients with unilateral or bilate...

PURPOSE In adults, sphenoid sinus agenesis is an extremely rare anomaly. The objective of this study was to investigate the prevalence of sphenoid sinus hypoplasia and agenesis using dental volumetric computed tomography (DVCT) in a population of Turkish individuals. MATERIALS AND METHODS DVCT scans in the axial, coronal and sagittal planes of the sphenoid sinus of 384 patients were examined ...
