DISCUSSION: Psoas abscess is rare and the main agents related to psoas abscess are Staphylococcus aureus, followed by Streptococcus and Escherichia coli. Retrofascial abscesses usually originate from bone lesions, including spine tuberculosis as our case, or due to contiguity of the retroperitoneal space. CONCLUSION: Psoas abscess related to Pott's disease is a difficult diagnosis, requiring high suspicious and proper investigation through good anamnesis, CT scan and culture.

Colovesical fistula in a young adult due to sigmoid colon diverticulitis undetected in computed tomography: Case report and review of literature.
