Image-guided locoregional therapies have an important role in the management of patients with hepatocellular carcinoma (HCC). Recent advances in the ablative as well as endovascular therapies have expanded the role of interventional radiologists in the treatment of HCC. Following image-guided therapy, an accurate response assessment is vital. Knowledge regarding normal postprocedure changes and subtle signs of residual or recurrent disease is important. In this review, we discuss various response evaluation criteria currently employed for HCC. We also discuss the postprocedure imaging features suggestive of residual disease or recurrence and imaging biomarkers for response assessment.

Infected coronary artery aneurysm (CAA) is a rare complication of percutaneous coronary intervention (PCI) and is associated with high morbidity and mortality. The management of infected CAA is unclear and is based on the clinical and imaging features. We report an interesting case of a giant infected right CAA secondary to Pseudomonas aeruginosa within four weeks of a drug eluting stent (DES) implantation. Chronological analysis of the coronary angiograms and computed tomography coronary angiography revealed rapid progression in the size of the aneurysm from small to a giant CAA over a period of four weeks. Patient remained afebrile throughout the hospital stay without any signs of septicaemia. In view of the rapid progression in size, surgical aneurysmal ligation with distal revascularisation was done with good post-operative recovery. Afebrile presentation of an infected CAA is very rarely reported in the literature as in our case. Early diagnosis using multimodality imaging and immediate surgical intervention are the cornerstone in the management of giant infected CAAs.
