Lumbar Spine
T12 – L1 OSTEOMYELITIS WITH BONE DESTRUCTION –
TB KIDNEY, SPINE, EPIDURAL ABSCESS, ADRENAL and PSOAS ABSCESS
58-year-old male with known history of tuberculosis. 
There is enlargement of the bilateral adrenal glands, with multiple nodular structures encompassing the left adrenal gland, which may also represent infectious process.
Examination of the lumbar spine on the CT scan shows findings consistent with TB osteomyelitis with destruction of T12 and L1 vertebral bodies with prevertebral and epidural collections extending into the spinal canal.
