Abstract: A patient who presented with multiple episodes of subarachnoid hemorrhage was diagnosed as having a large mid-basilar artery aneurysm that had no definable surgical neck. Balloon embolization was performed utilizing two detachable silicone balloons to occlude the mid-basilar artery and the aneurysm. The procedure was carried out with the patient fully awake and alert. One day after the procedure, the patient developed pontine and cerebellar ischemia which completely resolved after 5 days on heparin therapy. A follow-up angiogram performed immediately after the procedure and at 3 months demonstrated complete occlusion of the mid-basilar artery and the aneurysm. The patient was intact neurologically upon discharge 5 days after the embolization procedure and has since resumed his normal activities. Balloon embolization therapy may offer some advantages over surgical methods for the treatment of such therapeutically challenging aneurysms.

Abstract: Protein S deficiency is inherited as an autosomal dominant trait. Heterozygotes with a reduction of 50% in the plasma protein S concentration are at risk for the development of venous thromboembolism, often occurring at an early age without an apparent cause. In the majority of the patients thrombosis is restricted to the superficial or deep venous system of the legs. In this case report we describe the presence of mesenteric vein thrombosis in a 30-yr-old man with hereditary protein S deficiency. In his family protein S deficiency was also recognized in his mother, brother, and niece. Both his mother and brother had a history of thrombotic disease.

Abstract: We present a case of pansinusitis with orbital involvement associated with an allergic response to the fungus Curvularia (Cochliobolus) lunata. Key elements to the diagnosis included a predominant eosinophilic response of the sinus mucosa, the presence of a characteristic mucoid exudate containing fungal hyphae, peripheral blood eosinophilia, serum precipitins against C lunata, elevated serum total and Curvularia-specific IgE and IgG concentrations, and immediate cutaneous reactivity to C lunata antigen. This report suggests that an exaggerated allergic response should be considered in the pathogenesis of pansinusitis. The presence of fungal hyphae in sinus mucosal specimens should alert the physician to the possibility of this disease. Sinus fungal cultures, as well as thorough immunologic evaluation, of such patients is recommended.
