A middle aged male with Lymphoma had undergone CT guided retroperitoneal lymph node biopsy.
Subsequently, after 4 hours he started complaining of severe radiating pain.
A CT was done which showed a pseudoaneurysm from the lumbar artery wiht a large psoas hematoma.
Immediately the patient was taken up for DSA which showed the pseudoaneurysm from the right first lumbar artery branch.
This was embolised using nBCA-lipiodol mixture and microcoil.
Subsequently, the hematoma resolved.
