RESUMEN
We describe the MR findings in a case of chondroma arising from the falx. At MR imaging, the mass appeared well defined, lobulated, hypointense to isointense on T1-weighted images, and very heterogeneous with marked hyperintense areas on T2-weighted images. After contrast administration, this tumor enhanced slightly on delayed images.

The authors present the case of a 45-year-old man suffering from progressive quadriplegia due to an expansive C3-T2 epidural mass. Neuropathological examination demonstrated pseudotumor tissue. The patient had had an orbital pseudotumor 5 years before admission, and other systemic manifestations of an idiopathic inflammatory disease were discovered. This case is extremely rare. Nine cases of multifocal fibrosclerosis with central nervous system involvement are described in the literature. To the authors' knowledge, this is the first description of a cervical epidural pseudotumor. Modern imaging has made the diagnosis of such an entity possible, and it is important for the neurosurgeon to consider this syndrome because the combination of surgery and systemic medical therapy can ensure a long-term survival with good quality of life.

Since 1830, more than eighty cases of spinal cord abscesses have been reported. In half of these cases, it was unfortunately a post-mortem diagnosis. Magnetic resonance imaging (MRI) now gives new possibilities in the diagnosis and treatment of this rare pathology. We report here a case of cervical spinal cord abscess due to Streptococcus milleri. The clinical and laboratory findings, the MRI features, the pathogenicity of the offending pathogen and the surgical approach are discussed and compared with the data from the literature. The functional course was unexpectedly favourable in this patient. MRI allows prompt diagnosis and a precise localisation of the suspected abscess. Rapid surgical drainage is a critical prognostic factor for effective management of spinal cord abscess.
