Here is a typical case of extensive Tuberculous spondylitis (Pott disease) with marked Dorso-lumbar affection that is associated with paraspinal and intraspinal epidural collections as well as large bilateral Psoas abscesses.

A psoas or iliopsoas abscess is a compartment fluid collection that is located within the retro facial rather than the retroperitoneal compartment.

A previous MRI brain study was done 8 months before the current spinal study revealed a right intra-cranial small lesion with signal criteria highly suggestive of CNS tuberculoma.

Cytology of the aspirated psoas collections revealed tuberculous granulomatous infection with superadded suppuration.
