RESUMEN
Marchiafava-Bignami disease (MBD) is a rare condition often associated with chronic alcohol abuse. Clinical presentation is diverse. Characteristic magnetic resonance imaging (MRI) changes in the corpus callosum are the mainstay of radiological diagnosis. We present a case of a 54-year-old man with chronic alcoholism and peripherally enhancing lesion in the body of the corpus callosum on MRI Brain. Open biopsy of the lesion showed necrosis and demyelination. He was diagnosed with Marchiafava-Bignami disease based on clinical, radiology and histopathology findings. Our case represents the only case in the literature with antemortem histopathology findings describing MBD.

Several authors have reported advantages of the purely endoscopic (PE) approach over traditional purely microscopic (PM) techniques for many sinus and anterior skull base procedures. However, in pituitary surgery, the PE approach carries a number of limitations. Experienced microscopically-trained neurosurgeons are required to master the endoscopic technique which has a steep learning curve due to its one-handed nature and optically-distorted 2-dimensional view. We describe our novel technique, the sequential endoscopic and microscopic pituitary procedure (SEMPP) which does not require microscopically-trained neurosurgeons to alter their technique. We compare SEMPP with the PE approach in terms of outcome and safety. Retrospective chart review of consecutive SEMPP cases performed at our institution between January 2010 and December 2013 was conducted. Operative time, gross total resection rate, resolution of endocrine and visual dysfunction, hospital length of stay, cerebrospinal fluid (CSF) leak rate and revision rates were recorded. 32 patients were identified (50% female, mean age 53.0â¯years), and 33 SEMPP cases. Mean operating time was 132â¯min (range 90-200). 69% of patients experienced gross total resection. Most patients (81.3%) with preoperative visual deficit either experienced complete resolution or improved symptoms. The remainder experienced no change in vision. 12.5% (nâ¯=â¯4) of patients experienced intraoperative CSF leaks. All were repaired intraoperatively or with conservative management. Two patients (6.3%) experienced epistaxis managed with conservative measures. The SEMPP technique demonstrates comparable outcomes, complication rates and operative time to PE and PM techniques described in the literature.
