SUMMARYA 48-year-old woman presented with a 1-month history of severe lower back pain on a background of 24 h of mild fever and general tiredness with an associated right-sided foot drop. Five weeks after the onset and with no improvement in symptoms in spite of analgesia and physiotherapy, the patient had a lumbar spine MRI which demonstrated a collection extending from the facet joints of L5 and L6 to the iliacus muscle on the right. A CT-guided aspiration was performed with a lengthy hospital stay for intravenous antibiotic treatment. The culture and sensitivity study of the aspirate isolated Streptococcus pneumoniae.
BACKGROUND
Cervical spinal degenerative disease (SDD) and multiple sclerosis (MS) share clinical features, and misdiagnosis may occur. While cervical radicular pain in people with MS (PwMS) [1] should prompt a search for a compressive cause, it may uncommonly be a presenting symptom of MS in the absence of radicular compression [2-4], mostly due to root entry zone lesions. Painless cervical nerve root compression may occur in PwMS [5], where it is possible that pain pathways have been disrupted. Myelopathic symptoms could result from spinal cord demyelination or compressive canal stenosis; in particular, lower cervical or thoracic disc protrusions are easily missed [6] in people with progressive MS because a gradually worsening spastic paraparesis with bladder disturbance is one of the main clinical features in progressive MS and the cord may not be routinely imaged during follow-up. Multilevel disc herniations and compressive
