Introduction Inverted papilloma is a rare benign tumor of the nasal fossa, which usually originates from its lateral wall. Only 5% of cases demonstrate exclusive sinus involvement. Primary sphenoid sinus involvement is even rarer. Although considered a benign lesion, the tumor has a potentially invasive nature and has also been found to have an associated malignancy rate of 7 to 15%. Objectives...

BACKGROUND Isolated sphenoid sinus pathologies are relatively rare. In the majority of cases, symptoms do not arise in the early stages of the disease or are non-specific, therefore making diagnosis difficult. The aim of this study was to investigate the diagnostic process and the reasons for development of complications in patients with isolated sphenoid sinus pathology. MATERIAL/METHODS The...

OBJECTIVE To evaluate variations of some anatomic structures of sellar and parasellar regions and their possible differences between genders and age groups. PATIENTS AND METHODS Magnetic resonance images (MRI) of 380 patients were performed to analyze the dimensions of the sphenoid sinus, pituitary gland, optic chiasm, intra-cavernous carotid distances, distance between columella nasal - sphe...

Introduction Isolated disease of the sphenoid is rare and has often been overlooked due to its remote location and difficult access. Objective A retrospective study of the main causes of isolated sphenoid sinus diseases with discussion of the most appropriate methods of diagnosis and treatment. Methods A total of 46 cases of isolated sphenoid disease treated between January 2008 and December 20...

Giant cell tumor (GCT) of the sphenoid bone is a relatively rare entity and metachronous multicentric GCT of the sphenoid is even rarer; we are aware of only 3 previous cases in the literature. We describe here a tumor of the sphenoid bone that was identified 15 years after multiple resections of a GCT of the left inferior pubic ramus. Correlation is made between the histopathologic findings, M...

OBJECTIVE We report two extremely rare cases of isolated sphenoid 'fungal ball' in conjunction with vision loss. METHOD Case reports and a literature review concerning diagnosis and management of isolated sphenoid fungal ball in conjunction with vision loss. RESULTS A mycetoma or fungal ball resulting from isolated sphenoid fungal sinusitis is a rare disease. It is frequently difficult to d...

AIM The sphenoid sinus is deeply situated in the skull and is the least accessible paranasal sinus. The sphenoid sinus is surrounded by vital structures such as the optic nerve and internal carotid artery, and therefore additional radiological assessment of the sphenoid sinus and the related neurovascular structures is inevitable before surgery. The aim of this study was to note the anatomic va...

Pachymeningitis manifested by localized enhancing dural thickening adjacent to the clivus on MR images of two patients with sphenoid sinusitis and sixth-nerve palsy is presented. This is an unusual complication of sphenoid sinusitis. Prompt diagnosis and therapy may avoid significant intracranial complications.

PURPOSE To test the hypothesis that in patient with sunken eyes, sagging brain syndrome, bone remodeling is not limited to the orbits. Volumetric analysis of the sphenoid sinus is performed in this study. METHODS In this university-based retrospective case-control study, the dimensions of the sphenoid sinus were measured in four patients (2 males, 2 females; mean age 26.3 years, range 16-38 y...
