Morphological abnormalities of left temporal and sphenoid bone were discovered in a 17-year-old boy during a post-traumatic cranial CT scan examination. The patient had not suffered from audiological disorders previously. He did not complain of hearing loss, vertigo or autophony. Further clinical investigations were normal including micro-otoscopy and nasopharyngeal endoscopy. The Valsalva mane...

Primary non-Hodgkin lymphoma (PNHL) of the sphenoid sinus is a rare neoplasm that poses a diagnostic challenge to clinicians. The proximity of the optical nerve and canal to the sphenoid sinus is accountable for the high incidence of visual disturbance in PNHL of the sphenoid sinus. In particular, patients whose radiologic diagnosis reveals bone destruction in the lateral wall involved with opt...

BACKGROUND Giant cell reparative granulomas (GCRGs) are rare lesions in the cranial bones. We present a case of this rare lesion emanating from the clivus and replacing the sphenoid sinus, a highly unusual location for this entity. CASE DESCRIPTION The case and clinical course of a 29-year-old female who presented with a large sphenoid mass are described here. The patient presented with sympt...

PURPOSE We used MR imaging to analyze retrospectively the pattern of hyperostosis occurring concomitantly with recurrent sphenoid wing meningiomas. METHODS Bone involvement was compared in 12 corresponding CT and MR studies of 10 female patients with sphenoid wing meningiomas recurrence after earlier surgical treatment. Four of these had histologically confirmed meningiomatous infiltration of...

Arrested pneumatization of the sphenoid sinus is a normal anatomical variant. The aim of this report is to define cone beam computed tomography (CBCT) characteristics of arrested pneumatization of sphenoid sinus in an effort to help differentiate it from invasive or lytic skull base lesions. Two cases are presented with incidental findings. Both studies, acquired for other diagnostic purposes, ...
