[en] Background: Acute disseminated encephalomyelitis (ADEM) may be a rapidly progressive disease with different clinical outcomes. Purpose: To investigate the radiological findings of fulminant ADEM on diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) images, and to correlate these findings with clinical outcome. Material and Methods: Initial and follow-up magnetic resonance imaging (MRI) scans in eight patients were retrospectively evaluated for distribution of lesions on FLAIR images and presence of hemorrhage or contrast enhancement. DWI of the patients was evaluated as to cytotoxic versus vasogenic edema. The clinical records were analyzed, and MRI results and clinical outcome were correlated. Results: Four of the eight patients died, three had full recovery, and one had residual cortical blindness. The distribution of the hyperintense lesions on FLAIR sequence was as follows: frontal (37.5%), parietal (50%), temporal (37.5%), occipital (62.5%), basal ganglia (50%), pons (37.5%), mesencephalon (37.5%), and cerebellum (50%). Three of the patients who died had brainstem involvement. Two patients had a cytotoxic edema, one of whom died, and the other developed cortical blindness. Six patients had vasogenic edema: three of these patients had a rapid progression to coma and died; three of them recovered. Conclusion: DWI is not always helpful for evaluating the evolution or predicting the outcome of ADEM. However, extension of the lesions, particularly brainstem involvement, may have an influence on the prognosis

[en] We report the MRI appearances of an developmental anatomical variant of the basiocciput, with neuroimaging findings (CT and MRI). Such variants are commonly asymptomatic, but may be associated with episodes of meningitis. (orig.)

[en] In 1981, Currarino et al described a triad of findings that consist of partial sacral dysgenesis, presacral mass (anterior meningocele, enteric cyst, or presacral teratoma) and anorectal malformation. Currarino syndrome exhibits variable expressivity and the clinical presentation tends to vary with the age of the subject such as spinal anomaly detected in the fetus, imperforate anus in the newborn, and intractable constipation or neurologic symptoms in the infant and older child. At any age, meningitis can be the presenting symptom and imaging is required for proper investigation. Meningitis, sepsis, urinary tract infections, and, rarely, malignant transformation of a teratoma are serious potential complications. This pictorial review describes the imaging findings, clinical history, surgical interventions, and genetic background in 5 children with this syndrome who presented in our hospital in the interval of 1 year.

[en] The relationship between morphological changes in the spinal cord shown on computer-assisted myelography and symptoms was investigated in 73 patients with cervical spondylotic myelopathy. Flatness of the spinal cord was seen in many of the patients. Symptoms were likely to be severer with increasing the degree of flatness of the spinal cord. The length of the flat spinal cord will help to select the operative method for cervical spondylotic myelopathy. (Namekawa, K.)

[en] Computed Tomography (CT) of the spine was performed on 17 patients with myeloma in order to assess the role of the technique in recognizing and evaluating the extent of the lesions. Myelomatous lesions followed two patterns at CT: first of all, multiple focal lesions, whose density is either solid, liquid, or fatty; second, an extensive pattern involving the spongiosa of the vertebra, including the posterior arch. CT detected more lesions than conventional radiology; furthermore, the extent of the lesions was much better demonstrated by CT. CT should thus be performed: a) in case of pain and/or neurological findings in negative radiological examinations; b) to evaluate the extent of myelomatous lesions (mainly in the spine); c) in solitary myeloma CT may be performed on different bone segments with clinical symptomatology but normal X-ray findings
