RESUMO
A differential diagnosis between neurosarcoidosis and neurosyphilis is particularly problematic in patients with a positive serologic result for syphilis. We report here a patient with a solitary cavernous sinus sarcoidosis who had a history of syphilis and showed rapidly progressing cavernous sinus syndrome. A transsphenoidal biopsy was performed and a histopathologic examination revealed a non-caseating granuloma with an asteroid body. His facial pain disappeared after steroid therapy. He received oral prednisolone for one year. A follow-up magnetic resonance imaging of the brain revealed resolution of the mass over the cavernous sinus. Particularly in patients with a history of syphilis, neurosyphilis should be included in a differential diagnosis of neurosarcoidosis.
RESUMO
Arteriovenous malformations (AVMs) are composed of abnormally connecting feeding arteries as well as draining veins and lack a regulatory system. Frequent recurrences and unpredictable behavior are their main problems. Potential mortality and morbidity associated with therapeutic procedures must be considered with these patients. Improper treatment often aggravates the condition, potentially rendering therapy more complex. A multidisciplinary approach, including an endovascular approach, surgical excision, and flap reconstruction, is considered to completely eradicate an AVM. This study introduces a complicated case of AVM with massive bleeding through the external auditory canal that was treated with a multidisciplinary approach.
