Hemangiomas are the most common benign primary hepatic neoplasms, often being incidentally discovered. In most of the cases, they are small, asymptomatic and often require follow up. Giant hemangiomas are known as being larger than 5 cm and mostly consists of a cavernous haemangioma, is usually asymptomatic, diagnosed incidentally. In this study, we aimed to show that giant hemangiomas would be treated safely with surgical resection without transarterial embolization before the surgery. We present a 56-year-old male patient with liver hemangioma, who was diagnosed incidentally on thorax computarised tomography and consulted to thorax disease clinic with coughing complaint for a month. A case, which is rarely mentioned in literature, of a 30 cm sized asymptomatic giant cavernous hemangioma treated by surgical resection without any complication. We suggest that some patients should go through surgical treatment even if they do not have any complaint. Not only symptoms but also size and risk of rupture by trauma should be considered in these cases. However, all possible circumstances must be taken under consideration. Transarterial embolization is not the necessary.
