We report 13 patients with neurobrucellosis categorized into five groups: acute meningoencephalitis; papilledema and increased intracranial pressure, meningovascular, CNS demyelinization, and peripheral neuropathy. We treated the patients successfully, without relapse, with two or more antimicrobials: rifampicin, co-trimoxazole, and doxycycline.

The value of magnetic resonance (MR) imaging in evaluating granulomatous spinal infection was retrospectively assessed in 81 patients with proved disease; 27 were reexamined after administration of gadolinium diethylenetriaminepentaacetic acid, and 25 underwent follow-up studies. Blinded interpretations were correlated with clinical, microbiologic, and surgical findings. MR imaging enabled prediction of the presence of neurologic complications in 93% of patients and diagnosis of the type of infection in 94%, and correlated well with surgical findings in 24 of 27 patients. Vertebral intraosseous abscesses, meningeal involvement, subligamentous spread, and paraspinal abscess location were best identified on contrast-enhanced studies and were seen most frequently in tuberculous spondylitis. High signal intensity on T1-weighted images of previously affected vertebrae suggested healing and correlated well with symptoms. The authors conclude that MR imaging may be useful as the method of first choice for the initial assessment and posttherapy follow-up of patients with granulomatous spinal infection.

We analysed the clinical, imaging, electrophysiological, laboratory findings, course and prognostic factors in 31 patients with acute transverse myelitis (20 men and 11 women; mean age, 30 years; range, 18-51 years). All patients were assessed for maximal clinical deficit 'deficit score'; pattern-shift visual, auditory and somatosensory evoked potentials were measured, CSF was examined, and neuroimaging of the spinal cord and brain (MRI or CT myelography) was carried out. The myelitis was preceded by febrile illness in 25 (81%) of the patients. The site of the lesion was cervical in 11 (36%), upper thoracic in two (6%), lower thoracic in 16 (52%). MRI of the spinal cord was abnormal in 10 out of the 20 patients examined (50%); in the remaining 11 patients, only CT was carried out and it was normal in all of them. Somatosensory evoked potentials were abnormal in 19 (61%), while pattern-shift visual and brainstem auditory evoked potentials were normal in all patients. CSF was abnormal in 94% of patients with pleocytosis, increased protein or both. Eighteen patients (58%) had good outcome. All patients had monophasic illness. Three variables have emerged as being associated with significant worsening of the outcome: (i) abnormal somatosensory evoked potentials; (ii) abnormal imaging and (iii) high 'deficit score' at onset. Acute transverse myelitis affects a complete segment of the spinal cord, is monophasic and represents a localized form of postinfectious acute encephalomyelitis.
