SUMMARY Spontaneous lateral sphenoid cephaloceles arise from bony defects in the lateral sphenoid, in the absence of predisposing factors such as trauma, surgery, mass, or congenital skull base malformation. We reviewed CT and MR imaging findings and clinical data of 26 patients with spontaneous lateral sphenoid cephaloceles to better understand anatomic contributions to pathogenesis, varying c...

The findings and symptoms associated with a mucocele depend on its location and on the extent of bony erosion. Men and women are affected equally, and these lesions are mostly encountered during the third and fourth decades of life. We describe a frontal mucocele that accompanied diplopia, headache, and displacement of orbita and was successfully managed by endoscopic sinus surgery and medical ...

The sinus sphenoidalis is the paranasal sinus most centrally located in the skull base and known to vary extremely in dimensions. A very large volume of the sinus visible on skull radiographs is called sinus 'hyperaeration'. This finding has been described many times in the literature, but is generally rare. The term 'pneumosinus dilatans' is synonymously used to address an unexpectedly large p...

BACKGROUND Solitary involvement of the sphenoid sinus has rarely been reported in non-Hodgkin's lymphoma. Isolated oculomotor nerve palsy is uncommon as an initial presentation of malignant tumors of the sphenoid sinus. CASE PRESENTATION A 53-year-old woman presented with a three-month history of headache and diplopia. Neurological examination revealed complete left oculomotor nerve palsy. Ma...

OBJECTIVE In this report, we aimed to investigate the patients that presented at our clinic complaint with diplopia due to the abducens nerve palsy and neurosurgical disease. METHODS The study design was a retrospective review of ten cases with the abducens nerve palsy. The causes of the abducens nerve paralysis of our patients were as follows: two cases with head trauma, three cases with pit...

A 31-year-old lady presented to the otorhinolaryngology clinic complaining of right exophtalmus. Imaging studies revealed a right frontal sinus mass, suggestive of a mucocele, and fronto-ethmoidal ground glass opacification. In the operating room, the frontal sinuses were exposed through an osteoplastic flap, and connected to the nasal cavity through a Lothrop-like drainage pathway. The patholo...

BACKGROUND Primary inverted papilloma of the sphenoid sinus is rare. The tumor is considered locally aggressive. In selected cases inverted papilloma can be associated with squamous cell carcinoma. Radiologic imaging is a key to an accurate diagnosis. AIM We analyzed patient with inverted papilloma in sphenoid sinus which was removed with endoscopic surgery. MATERIAL AND METHODS We discuss ...

A male patient aged 37 years with a history of cranioencephalic trauma 21 years ago, reports a left frontal tumor beginning 4 months ago. Magnetic resonance imaging revealed a lesion suggesting mucocele (Figure 1). The patient underwent endoscopic bilateral frontal ethmoid sinusectomy. The option was made for external left frontal ethmoidectomy due to intense bone sclerosis in the frontal reces...
