A 63-year-old man, identified as Mr. Quan, presented with severe abdominal pain, vomiting, jaundice, chest pain, and shortness of breath; doctors later discovered three severely narrowed coronary arteries and a 10 cm liver abscess.

Ms. Hong, 21, experienced chest pain for a month, attributing it to pregnancy, but doctors discovered a superinfected abscess and drained nearly 150 ml of pus.
