ABSTRACT
Pyogenic spondylodiscitis (PS) is a highly morbid and potentially fatal bacterial infection with an increasing incidence in recent decades. Its diagnosis and treatment are challenging, especially with the expansion of multidrug- or extensively drug-resistant bacteria. We report a rare case of PS caused by carbapenem-resistant Pseudomonas aeruginosa (CRPA) that was treated with ceftazidime-avibactam (C/A). The choice of C/A therapy was based on the patient's bacterial sensitivity profile and intolerance to the initial therapeutic regimen (polymyxin B and meropenem). The total antimicrobial treatment time was seven weeks. The evolution of the clinical course met the cure criteria, which was characterized by remission of signs and symptoms, normalization of inflammatory markers, and radiological improvement over 18 months of clinical follow-up. This is a rare case of CRPA spondylodiscitis that responded to C/A treatment.
ABSTRACT
Idiopathic spinal cord herniation is a rare cause of progressivemyelopathy, especially in the absence of a history of spinal or surgical trauma. The radiological diagnosis ismade through a myelography or an MRI exam. The spinal cord is pushed anteriorly, buffering the dural defect and leading inmost cases to Brown-Séquard syndrome. The present study describes the case of a male patient with a clinical picture of progressive thoracicmyelopathy. In the clinical and radiological investigation, an idiopathic spinal cord herniation on the chest level was identified. During the surgery, the spinal cord was reduced to the natural site, taking its usual elliptical shape, and the dural defect was repaired with a dural substitute. The numbness of the patient improved, and the shocks in the lower limbs disappeared. A postoperative MRI confirmed the surgical reduction of the herniation and the restoration of the anterior cerebrospinal fluid (CSF) column to the spinal cord. The authors describe the clinical, radiological, intraoperative, and postoperative evolution.
