Meigs syndrome is characterised as the presence of hydrothorax and ascites in the presence of solid benign ovarian tumours that resolve after the tumour is removed. Pseudo-Meigs syndrome is defined as hydrothorax and ascites associated with pelvic tumours other than those identified in Meigs syndrome. Meigs' syndrome is diagnosed based on a triad of an ovarian fibroma, pleural effusion and ascites. For one year, a 45-year-old woman had abdominal distention and pain, as well as breathlessness for one month. Hydrothorax, ascites, and a massive pelvic tumour palpable abdominally, as well as another mass palpable per vaginally, were discovered during the clinical evaluation and investigations. For symptomatic relief, thoracocentesis and abdominal paracentesis were performed. An exploratory laparotomy was performed. Total hysterectomy was performed, as well as bilateral salpingo-oopherectomy. The mass was diagnosed as an ovarian, serous, borderline tumour after a histopathological review. Pseudo-Meigs syndrome was verified by the immediate postoperative resolution of hydrothorax and ascites.
