Concomitant presence of CE and hepatocellular carcinoma (HCC) is a rare clinical scenario. A 70-year-old male patient presented with acute abdominal pain to the surgical outpatient department. On evaluation, a cystic lesion with solid components and free fluid in the abdomen was observed, which led to multiple differentials in the working diagnosis. A CT showed the mass to have a delayed enhancement. Surgical exploration revealed a partially ruptured hydatid cyst with daughter cysts in the abdominal cavity and a solid-component mass lesion. We proceeded with a right partial hepatectomy. Pathological evaluation revealed a pale mass lesion with a large collapsed cyst. HCC with unusual dense fibrillar fibrosis and cystic interface with normal parenchyma was observed. This case connects the multimodal assessment of radiology, surgery and pathology.<\/jats:p>","DOI":"10.1136\/bcr-2021-246534","type":"journal-article","created":{"date-parts":[[2021,12,3]],"date-time":"2021-12-03T11:55:29Z","timestamp":1638532529000},"page":"e246534","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Synchronous
