Mucocele of the Sphenoid Sinus

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. A transnasal endoscopic sphenoidectomy was performed in both patients, in one - with an evacuation of the mucocele and marsupialization, and in the other - with a balloon dilatation of the natural foramen of the sinus. Postoperatively, a complete reversal of the symptoms was observed in both patients. Mucocele of the paranasal sinuses should be considered as a diagnosis in cases of persistent headache with a primarily retrobulbar location and eye symptoms. Computed tomography and magnetic resonance imaging can be used to successfully diagnose the disease. The transnasal endoscopic sphenoidectomy is the therapeutic method of choice which allows evacuation of the mucocele, while the marsupialization allows good drainage and prevents recurrence

Initial Experience with O-Arm Navigated Spinal Surgery - Report on Two Cases

Image-guided spinal surgery is becoming increasingly popular because it allows surgeons to achieve minimal invasiveness and maximum precision in the performed procedures

Thoracic Meningioma In Combination With Severe Lumbar Spinal Stenosis Presenting With Atypical Neurological Deficit

We report on a case of a 47-year-old female patient with a long history of low back pain irradiating bilaterally to the legs. Twenty days before admission to our clinic, she had developed progressive weakness in the legs, more pronounced on the left side. The initial neurological examination revealed signs of damage to both the cauda equina and the spinal cord. The neuroimaging studies (computed tomography, myelography and magnetic-resonance tomography) found spinal stenosis most severe at L4-L5 level, and right lateral thoracic intradural-extramedullary tumor at T9-T10 level
