Atypical Presentation of Mycobacterium Tuberculosis in an Infant.

Tuberculosis of the skeletal muscle is very rare which is often missed in the early stages. This leads to delay in treatment resulting in irreversible limb deformity and loss of function. The authors describe a case of healthy child with an intramuscular cystic swelling above the elbow joint. The pus showing acid fast bacilli morphologically resembling Mycobacterium tuberculosis was also isolated in culture. Following the diagnosis and confirmation, the child was treated successfully with anti tubercular drugs.

Intramuscular Abscess Causing Radial Nerve Palsy

Radial nerve palsy is one of the commonest upper limb compressive neuropathies encountered in orthopaedic practice. More frequently associated with fractures of the humeri, it can also be the result of other atraumatic causes such as the so-called 'Saturday Night Palsy'. Inthis article, a case is presented where a palsy of the radial nerve was caused by the expansion of an intramuscular abscess in a patient with chronic renal failure. This is a relatively rare cause of radial nerve palsy that resolved progressively after surgical drainage.

Tuberculous abscess of rectus abdominis muscle.

Tuberculosis of skeletal muscle is very rare. A case of tuberculous abscess in rectus abdominis muscle is described in a seven year old male child. The patient presented with an abscess in the anterior abdominal wall, which subsequently ruptured. The diagnosis was made by histological examination of the excised tissue following local debridement.

Pyogenic Arthritis and Paraspinal Abscess Following Facet Joint Steroid Injection: A Case Report / 대한척추외과학회지

STUDY DESIGN: A case report and literature review. OBJECTIVES: To discuss pyogenic infections of the facet joints and paraspinal intramuscular abscess that developed after a steroid injection into the facet joint of the lower back. MATERIAL AND METHODS: A 39-year-old man who received a steroid injection to the facet joint, 3 weeks prior to admission, experienced increasing lower back pain and a high fever. RESULTS: Plain radiographs of the lumbar spine showed osteolytic erosion of the articular process at the L3-4 facet joint. On a CT scan, the destructed facet joint was connected to a paraspinal intramuscular abscess. MR images also showed a paraspinal intramuscular abscess on multiplane views. In the operative field, the paraspinal abscess, which extended from 2nd to 5th lumbar vertebrae, was found on the right side, with the L3-4 facet destructed and directly connected to the abscess. Some chalky material, considered to be steroid crystals, was found at the L3-4 facet joint. Drainage, debridement and irrigation were performed. Staphylococcus aureus was isolated from the culture. After surgery, intravenous antibiotics were administered, and the patients' symptoms quickly resolved. CONCLUSIONS: A posterior facet joint injection has its own risks of developing a pyogenic infection of the facet joint. Pyogenic facet joint infections may progress to a paraspinal intramuscular abscess. Surgical drainage is mandatory in cases resistant to antibiotic treatment, with evidence of pus formation on imaging studies.
