The spinal canal is an uncommon site for abscess formation resulting from bloodstream disseminated infection. Prognosis is often unfavorable. Rapid treatment is essential for satisfactory neurological recovery. Abscesses within the spinal canal are thus diagnostic and therapeutic emergencies. The neuro-infectious and inflammatory manifestations and laboratory findings vary considerably and are insufficient for diagnosis. MRI plays a decisive role. The most commonly reported signs are the presence of an intramedullary collection giving a low-intensity signal on T1-weighted images and a high-intensity signal on T2-weighted images with peripheral contrast uptake and generally extended adjacent medullary edema. We report here five cases of spinal canal abscesses diagnoses with MRI at different stages of development (pre-suppurative myelitis in two cases, constituted abscess in three cases). For each case we reviewed the clinical course and describe the details of the imaging findings. In our series, the collected abscesses presented as round lesions within the canal with contrast uptake. It is noteworthy that the periependymal gray matter adjacent to the lesion also took up the contrast agent in all patients with a collected abscess. This sign has not been described previously and appears to be a going argument orienting the diagnosis towards an infectious rather than tumoral formation.
