Touibi SUMMARY: Symptomatic Rathke cleft cysts (RCC) are reported in the sellar and suprasellar regions, but no case of sphenoidal RCC has been reported. We report a case of sphenoidal RCC in a 41-year-old man. The lesion was revealed by headaches and diplopia. Symptoms disappeared transiently after a spontaneou...

Pituitary abscess is an uncommon pituitary lesion. Its clinical diagnosis can be difficult to distinguish from other pituitary lesions. This pathology is characterised by vague symptoms of headaches, generalised tiredness and hypopituitarism manifestations. A history of recent meningitis, paranasal sinusitis or head surgery can be a suggestive of the source of infection.A 20-year-old man was ad...

BACKGROUND Extranodal nasal-type natural killer (NK)/T-cell lymphoma represents a rare entity, typically originating in the nasal cavity, palate or midfacial region. Signs and symptoms include non-specific rhinitis and/or sinusitis, nasal obstruction, epistaxis, facial swelling and development of deep necrotic ulceration in the midline of the palate, causing an oronasal defect. Differential dia...

Meningitis due to Streptococcus pneumoniae is a rare complication of trans-sphenoidal surgery. We present the case of a patient who developed pneumococcal meningitis with associated bacteraemia after elective endoscopic trans-sphenoidal resection of a pituitary macro-adenoma. After initial treatment with ceftriaxone and dexamethasone, the patient made a good recovery and dexamethasone was disco...

A 46-year-old woman presented with an intermittent nontraumatic cerebrospinal fluid (CSF) left rhinorrhea. A multidetector computed tomographic (MDCT) study was performed to investigate a CSF fistula (Figure). The sphenoidal sinus is prone to CSF leakage, when anatomical variations occur. The basilar expansion is a posterior expansion of the sphenoidal sinus (postsellar). It is considered criti...

A 40-year-old male presented with headache, complete loss of vision in the right eye and decreased vision of the left eye. On examination, fundoscopy revealed secondary optic atrophy in the right eye and pale temporal disc in the left eye. MRI brain revealed a soft tissue mass arising from sphenoid sinus, eroding the overlying bone and extending into the sellar and parasellar regions up to the ...

PURPOSE To investigate the prevalence and physical basis of a specific form of MR susceptibility artifact that may be seen in the pituitary gland near the junction of sellar floor and sphenoidal septum. MATERIALS AND METHODS Coronal, T1-weighted MR images of the pituitary glands in 50 subjects without clinical evidence of pituitary or sphenoidal sinus disease were reviewed to determine the pr...

OBJECTIVES Odontogenic sinusitis usually affects the maxillary sinus but may extend to the anterior ethmoid sinuses. The purpose of this study is to determine the percentage of odontogenic maxillary sinusitis extended to the anterior ethmoid sinuses and determine also the surgical resolution differences between odontogenic maxillary sinusitis and odontogenic maxillary associated to anterior eth...

PURPOSE To delineate the relationship between the optic nerves and the posterior paranasal sinuses using CT data. METHODS Direct coronal sinus CT scans of 150 consecutive patients with chronic inflammatory sinus disease were reviewed by two radiologists. Axial oblique reconstructions along the course of the optic nerve were obtained for the first 100 patients. The direct relationship between ...
