Focal nodular hyperplasia (FNH) is one of the three most common benign solid liver tumours along with hemangiomas and adenomas. FNH is considered a vascular abnormality that usually follows an uneventful course after accidental discovery on CT or MRI for an unrelated medical problem and rarely requires any treatment. These lesions are stable in nature with minimal risk of rupture and essentially no risk for malignant degeneration. The general recommendations for an asymptomatic FNH are observation only, regardless of size of the mass. However, the consequences of a ruptured liver mass can be very serious as abdominal bleeding may be catastrophic so accurate diagnosis is essential. Here we present the only known case of a patient with multiple FNH nodules who ruptured two of her lesions, the first treated with a left hepatectomy and the second with embolization. A discussion of the management of her ruptured tumours follows and highlights how little evidence is available for the treatment of multiple ruptures of FNH or how to properly risk stratify patients.
