Several approaches to the cerebellopontine angle and internal auditory canal have been described for the removal of large acoustic tumors. Of these, the translabyrinthine removal of the large cerebellopontine angle tumors requires extensive removal of bones in order to manage the low-lying tegmen, the anterior sigmoid sinus, and the high jugular bulb. We removed 4 large cerebellopontine angle tumors by the translabyrinthine approach alone. All tumors were totally removed with acceptable facial nerve function. There was a case of CSF leak which was repaired at the revision surgery.

Prototheca wickerhamii is an achlorophyllic algae that rarely acts as an opportunistic pathogen in humans. We report the case of a 66-year-old female patient with a history of diabetes mellitus who presented with a pus-like discharge from face, facial redness, and swelling. The patient was admitted to the emergency room with worsening facial pain. Gram staining from pus-like discharge revealed yeast like features; however, an isolated colony on a blood agar plate was not identified using VITEK 2 (Biomerieux) or matrix-assisted laser desorption/ionization time-of flight mass spectrometry (MALDI-TOF) using VITEK MS (Biomerieux). Lactophenol cotton blue staining of the colony revealed characteristic sporangia and endospore features. After performing the protein extraction procedure for filamentous fungi (mold) isolates using ethanol and formic acid, MALDI-TOF MS identified the colony as Prototheca wickerhamii, with 99.9% confidence. This case indicates that Prototheca spp.require specialized sample preparation steps, such as the ethanol/formic acid extraction procedure, for identification using MALDI-TOF MS.

The occurrence of a trigeminal neuropathy associated with connective tissue disease is rare. Trigeminal neuropathy in connective tissue disease is predominantly sensory and it is characterized by numbness, hypesthesia, slurred speech, and touch pain. Although the pathogenesis of trigeminal neuropathy associated with connective tissue disease remains obscure, the main pathologic findings are vasculitis and neuritis. A case of trigeminal neuropathy associated with mixed connective tissue disease is described, and the incidence, symptoms, pathophysiology, treatment of the disease is discussed.

PURPOSE: To characterize the MR findings for a differential diagnosis and to make a plan for treatment by interventional technique of the vascular masses with/without hypertrophic feeding vessels of the head and neck. SUBJCETS AND METHODS: Seven patients with vascular masses of the head and neck proved by pathology, angiography, clinical findings were included. Vascular masses included 4 venous malformations, a capillary hemangioma, and a hemangiopericytoma, a hemangioma combined with arteriovenous malformation. 7 patients had MR studies with 1.0T and 1.5T using routine TI-, T2- weighted spin echo sequences, and contrast enhancement. 4 MR angiography, 3 inversion recovery, and 6 contrast angiography were studied from 7 patients RESULTS: All vascular masses demonstrated higher than muscle signal intensity on Tl-weighted images, bright signal intensity on T2-weighted images, and prominent enhancement, except AV hemangioma combined with prominent arteriovenous malformation on postcontrast scan. Three hemangiomas demonstrated distinct serpiginous signal voids. Venous malformations demonstrated venous lakes seen as homogenous regions of high signal intensity and phleboliths seen as low signal foci on images. Inversion recovery was the best pulse sequence for evaluation of the extent of lesion. CONCLUSION: MR findings of the vascular masses of the head and neck are useful in delineating the extent of the disease, differentiating venous malformation or cavernous hemangioma from other hemangiomatous lesions including hypertrophic feeding vessels, and making a plan for treatment by interventional technique also.

OBJECTIVE: To investigate the length of hospital stay (LOS) after stroke using the database of the Korean Health Insurance Review & Assessment Service. METHODS: We matched the data of patients admitted for ischemic stroke onset within 7 days in the Departments of Neurology of 12 hospitals to the data from the database of the Korean Health Insurance Review & Assessment Service. We recruited 3,839 patients who were hospitalized between January 2011 and December 2011, had a previous modified Rankin Scale of 0, and no acute hospital readmission after discharge. The patients were divided according to the initial National Institute of Health Stroke Scale score (mild, ≤5; moderate, >5 and ≤13; severe, >13); we compared the number of hospitals that admitted patients and LOS after stroke according to severity, age, and sex. RESULTS: The mean LOS was 115.6±219.0 days (median, 19.4 days) and the mean number of hospitals was 3.3±2.1 (median, 2.0). LOS was longer in patients with severe stroke (mild, 65.1±146.7 days; moderate, 223.1±286.0 days; and severe, 313.2±336.8 days). The number of admitting hospitals was greater for severe stroke (mild, 2.9±1.7; moderate, 4.3±2.6; and severe, 4.5±2.4). LOS was longer in women and shorter in patients less than 65 years of age. CONCLUSION: LOS after stroke differed according to the stroke severity, sex, and age. These results will be useful in determining the appropriate LOS after stroke in the Korean medical system.
