Brain abscesses: etiologic categorization with in vivo proton MR spectroscopy.

Purpose: To compare the metabolite patterns observed at in vivo proton magnetic resonance (MR) spectroscopy of brain abscesses in patients for whom bacteriologic information was obtained from cultures and to categorize the MR spectral patterns with respect to the underlying etiologic agents.

Materials And Methods: MR imaging and in vivo single-voxel proton MR spectroscopic data obtained from 75 patients with brain abscesses were retrospectively analyzed. Ex vivo spectroscopic experiments with the pus from 45 of these patients also were performed, and the data were further categorized on the basis of bacteriologic information.

Square cervical laminoplasty incorporating spinous process: surgical technique.

Background: We have used a laminoplasty technique in multilevel cervical canal stenosis that incorporates spinous process in the neural arch and does not require free graft or foreign material.

Methods: In this technique, laminae and spinous processes were used to enlarge stenotic cervical spinal canal. Three patients (mean age 34.

MR demonstration of brain abscess rupture into the subarachnoid space and its possible implication in management.

Background: Rupture of brain abscess into the subarachnoid space as a cause of meningitis is rare. Early diagnosis improves the outcome. There is no previous report of MR demonstration of rupture of brain abscess into the subarachnoid space.
