Abstract
Between January 1981 and July 1991, 61 patients with hepatic haemangiomata were examined at Westmead Hospital. There were 14 males (22%) and 47 females (78%). The age range was 26–85 years with a median of 49 years. Forty‐one had abdominal symptoms but these could be attributed to a haemangioma in only seven cases. There was at least one subcapsular lesion in 17 (28%). Six of the seven symptomatic lesions were subcapsular and five of these were giant haemangiomata (i.e. more than 4 cm in greatest diameter). One large symptomatic lesion was intrahepatic. No association was observed between hepatic haemangiomata and other hepatic or extrahepatic diseases. Haemangiomata were resected from six patients, four of whom were symptomatic. Symptoms improved in all four but did not resolve completely in any. Follow‐up ranged from nil in five patients to 108 months in one. The median follow‐up was 12 months after initial diagnosis. Ten patients showed evidence of change in their lesions or symptoms while under observation. Only three had worsening symptoms or suspected change in size of a haemangioma.This study highlights the benign, static nature of most hepatic haemangiomata. When this lesion is suspected, the diagnosis should be confirmed with ultrasound (US) and labelled red blood cell scanning (RBCS). Referral for evaluation by a specialist hepatobiliary surgery unit is necessary when symptoms are intolerable, increasing size is definitely demonstrated or the diagnosis is uncertain and cannot be established without specialized investigations. Bleeding into or from these lesions is rare.
