Isolated tuberculous abscess in longissimus muscle.

Muscle's tuberculosis (TB) without coexistent active skeletal involvement is very rare. We presented a case of tuberculous abscess of longissimus muscle in a young immunocompetent female. Magnetic resonance imaging showed a well-circumscribed lesion in the longissimus muscle. No bony abnormality was noticed. An ultrasound-guided biopsy revealed the presence of granulomatous features on cytological pathology. A good response was seen with antitubercular treatment. TB should be considered in the differential diagnosis of any unexplained soft-tissue swelling in people born in tubercular endemic areas. To the best of our knowledge, our observation is the third reported case in immunocompetent patient.

Epidural and Paraspinal Abscess Presenting as Acute Low Back Pain.

A 56-year-old man sought care from a primary care physician (PCP) 5 days after lifting a heavy box produced acute, isolated lumbar pain. The PCP diagnosed a lumbar disc herniation and referred the patient to physical therapy without diagnostic imaging. Due to the presence of multiple red flags leading up to and during examination, the patient was transferred to the emergency department for further evaluation. Magnetic resonance imaging revealed a spinal epidural abscess with an associated multiloculated abscess within the adjacent left paraspinal muscles.
