REVIEW
Michael S Vaphiades
Two magnetic resonance imaging (MRI) signs of pituitary apoplexy are the "pituitary ring sign" and "sphenoid sinus mucosal thickening". The occurrence of both these MRI signs together in patients with ischaemic pituitary apoplexy was investigated. A literature review searching the terms "pituitary ring sign" and "sphenoid sinus mucosal thickening" in the context of pituitary apoplexy from 1990 until present was performed. To be included in the study, each case had to have ischaemic pituitary apoplexy defined as acute expansion of a pituitary adenoma or, less commonly, in a non-adenomatous gland, from infarction without haemorrhage or very little haemorrhage and a T1-weighted MRI of the brain with contrast that displayed both "sphenoid sinus mucosal thickening" and a "pituitary ring sign" either on an actual study (the author's cases) or in a figure in an article from the literature that could be reviewed and clearly illustrate these two signs...

A 51-year-old man who had undergone right orbital decompression 5 months earlier developed a meningoencephalocele extending in the right sphenoid sinus through a skull base defect of the right ethmoid, sphenoid, and frontal bones. The authors report the third case to their knowledge of meningoencephalocele with cerebrospinal fluid leak after orbital decompression and discuss its management and measures that can be taken to prevent this rare but serious complication.

Mucocele of the paranasal sinuses is a rare disease with slow evolution. It is a benign, encapsulated and destructive formation filled with mucous fluid and tapistrated with respiratory epithelium. Of all the paranasal sinuses, the sphenoid sinus is affected in only 1-7% of the cases. We present two cases of mucocele of the sphenoid sinus involving the posterior ethmoidal cells. We consider here their clinical presentation, use of neuroimaging in the diagnosis, surgical care and postoperative results. Both patients presented with a history of persistent headache and in addition, one of them had a paresis of the right oculomotor and abducens nerves...

OBJECT: Skull base meningiomas carry a non-negligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (WHO grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

OBJECTIVE: This study adds important information regarding the morphological alterations caused by growth hormone hypersecretion in the skull and craniocervical junction (CCJ). A variably asymmetric skull due to acromegaly coexists with expansion of the paranasal sinuses and multiple Wormian bones. CASE REPORT: A pathologically asymmetric dry skull of a European male, aged 38 years at death, with cranial vault and skull base thickening is described. The extensive paranasal sinus pneumatization caused a generalized thinning of the bony walls...

INTRODUCTION: The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures. OBJECTIVE: The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations between them which are crucial anatomical landmarks for preoperative planning. METHODS: This study was performed using paranasal multidetector computed tomography images that were obtained with a section thickening of 0...

OBJECTIVE: This report examines the utility of the preoperative image to orientate the surgeon in the sphenoid sinus during an endoscopic endonasal transsphenoidal approach (ETSS). METHODS: ETSS was performed in 100 cases of sellar lesion and used to classify the sphenoid sinus septum shape. Preoperative CT and MRI scans were taken for two types of coronal imaging: conventional and oblique. Expected sphenoid sinus septum shape was compared with those from ETSS to estimate concordance...

BACKGROUND: We report a rare case of hemorrhagic cavernous sinus hemangioma with sudden onset of abducens palsy. CASE DESCRIPTIONS: Sudden onset of diplopia occurred in a 49-year-old female. Head computed tomography (CT) findings revealed a high density mass in the right cavernous sinus with protrusion to the sphenoid sinus. Endoscopic endonasal surgery was performed, though early recurrence was noted. A gamma knife surgical procedure was then performed to prevent early recurrence after histopathological confirmation of cavernous sinus hemangioma...

Chondromyxoid fibroma (CMF) is a rare benign tumor, usually arising in the metaphysis of long bones in young adults. Occurrence in craniofacial bones presents a particular diagnostic challenge given its unusual location and resemblance to malignant mimics. We describe the clinicopathologic features of 25 cases of craniofacial CMF identified between 1999 and 2017. Patients were 14 men and 11 women, with median age of 44 years (range, 5 to 83 y). Sites of involvement were sphenoid (7), ethmoid (5), maxilla (3), occipital (2), nasal septum (2), palatine (2), temporal (2), orbit (1), and undisclosed skull (1)...

BACKGROUND: Spheno-orbital meningiomas (SOMs) are complex tumors involving the sphenoid wing, the orbit, and sometimes the cavernous sinus with bone hyperostosis and sheet-like dural involvement. Optimal removal, proptosis cure and visual preservation remain a challenge. OBJECTIVE: To study the management of surgically treated SOMs METHODS: The clinical records of 130 consecutive patients undergoing surgery for SOMs were retrospectively collected in a database during a 20-year period to analyze symptoms, surgical technique, clinical outcome, and follow-up...

Sphenoid sinus mucoceles (SSMs) are rare, benign lesions that can expand, often presenting with ocular symptoms-decreased vision, diplopia, visual field defects, proptosis, and external ophthalmoplegia. Reported cases are few, visual compromise varies, and factors affecting visual prognosis are poorly characterized. We investigate whether prompt surgical intervention (within 2 weeks of visual symptom onset) affects best-corrected visual acuity (BCVA) regained in patients with vision loss secondary to compressive SSM...

Tension pneumosella (TP) is a rare entity reported as the invagination of the sphenoid sinus mucosa into the skull base after endonasal transsphenoidal surgery. Few studies have reported on TP, and in these studies, invagination is confined to either the intrasellar or suprasellar area. We encountered a case of unexpected prominent TP toward the intracranial space 5 years after endoscopic endonasal transsphenoidal surgery (EETS) for a nonfunctioning pituitary adenoma. In addition, we present a hypothesis of the underlying mechanism by a pressure gradient change between the extracranial and intracranial space in TP formation...

This report describes a bilateral sphenoid sinus mucosal flap for the repair of a sellar floor defect and CSF leak following endoscopic endonasal skull base surgery. The key advantage of this technique is enabling the sphenoid mucosal flaps to remain vascularized, which reduces postoperative complications including CSF leakage, recurrent sinusitis, meningitis, encephalitis and pneumocephalus. The use of this technique is a viable and possibly favorable alternative to free grafts in the reconstruction of small to medium sized sellar defects with low flow or absent CSF leaks base surgery...

The bone SPECT/CT allows for precise anatomic delineation of bone activity, which can be valuable for diagnosis of nonmalignant bone diseases. We report an extremely rare case of sphenoid sinus aspergillosis, observed on bone SPECT/CT imaging, as an isolated disease in an immunocompetent individual. A 58-year-old woman with a history of plantar fasciitis was assessed for infection in the tarsal bones. Planar bone scan image revealed incidental focal lesion in skull base, which was considered to be the left sphenoid sinusitis by the bone SPECT/CT scan...

INTRODUCTION: Additional robust criteria to predict early postoperative recurrence of non-functioning pituitary macroadenomas (NFMAs) are needed. Recently, a new classification of pituitary tumours has been proposed which is based on both radiological and histological criteria and allows the grading into 5 groups of different potential aggressiveness. The aim of this study was to use this classification to further characterize predictive factors of recurrence in an independent series of NFMA...
