Hepatic hemangioma is the most frequently occurring benign tumor of the liver. Hepatic hemangioma rupture is a rare phenomenon, which can lead to life-threatening conditions. Here, we report a case of hepatic hemangioma rupture caused by blunt trauma. Explorative laparotomy was performed due to unstable vital signs and abdominal massive hemoperitoneum revealed on computed tomography. We detected arterial bleeding from a hepatic hemangioma and performed primary suture of the liver and postoperative angiographic embolization.

Hepatic hemangioma is the most common benign liver tumor and must be considered in the differential diagnosis of other space occupying hepatic masses. A 54-year-old man was referred to evaluate bone metastases of lung adenocarcinoma. In our case, we thought that a focal hepatic uptake in the bore scan was a metastatic lesion, because of underlying lung adenocarcinoma. However, the findings of abdominal CT and Tc-99m RBC scan results were deemed to be characteristic of hepatic hemangioma. The biopsy of the lesion was not performed.

Hemangioma is the most common benign tumor of the liver, with a prevalence estimated as high as 7%. Tc-99m red blood cell (RBC) hepatic blood pool scan with single photon omission computed tomography (SPECT) imaging is extremely useful for the confirmation or exclusion of hepatic hemangiomas. The classic finding of absent or decreased perfusion and increased blood pooling ("perfusion/blood pool mismatch") is the key diagnostic element in the diagnosis of hemangiomas. The combination of early arterial flow and delayed blood pooling ("perfusion/blood pool match") is shown uncommonly. In giant hemangioma, filling with radioactivity appears first in the periphery, with progressive central fill-in on sequential RBC blood pool scan. However, the reverse filling pattern, which begins first in the center with progressive peripheral filling, is also rarely seen. Studies with false-positive blood pooling have been reported infrequently in nonhemangiomas, including hemangiosarcoma, hepatocellular carcinoma, hepatic adenoma, and metastatic carcinomas (adenocarcinoma of the colon, small cell carcinoma of the lung, neruroendocrine carcinoma). False-negative results have been also reported rarely except for small hemagniomas that are below the limits of spatial resolution of gamma camera.

Hepatic hemangiomas (HH) - classified into congenital hepatic hemangiomas (CHH) or infantile hepatic hemangiomas (IHH) - are benign vascular tumors that are mainly asymptomatic, but may cause clinical problems that require treatment. While focal, multifocal, and diffuse IHH are responsive to propranolol treatment, CHH is mainly focal and thought to be resistant to treatment with propranolol. The clinical and imaging distinctions between CHH and IHH in cases of focal lesions can be challenging, while histopathological distinction is mostly lacking in the clinical setting. We report 4 neonatal symptomatic cases of focal HH treated with propranolol, with partial or complete resolution of the tumor, and the positive hemodynamic effect of propranolol in one case. We believe that although clear differentiation cannot be achieved between CHH and IHH without histopathological examination in cases of focal HH in neonates, propranolol treatment should be attempted in symptomatic cases since its benefits outweigh the possible small risk of side effects of propranolol.

A hepatic hemangioma is the most frequent benign liver tumor. Once rupture occurs, the bleeding can barely be controlled by using conservative management or endovascular treatment. We report a case of traumatic hepatic hemangioma rupture. A 60-year-old man was referred to our hospital under cardiopulmonary cerebral resuscitation (CPCR). CPCR was continued for 16 minutes after his admission to the emergency room (ER). Computed tomography (CT) showed fluid accumulation in the peritoneal cavity with active contrast extravasation in the left lateral segment of the liver. Percutaneous transarterial embolization and massive transfusion were carried out. Embolization did not stop the bleeding, we decided on an exploration and then resected the lateral segment of the liver to control the bleeding. The specimen showed a ruptured hemangioma in the liver segment.

Authors analyzed sonographic findings of 59 cases of hepatic hemangioma, with had been diagnosed through examination in our Medical. dept, from Januray, 1985 to December 1989. The results of the analysis are as follows: 1) The hepatic hemangioma was found in 59 cases(0.33%) among the 17,714 insureds. 2) In all 59 cases who have hemangioma, hemangioma was found in 37 cases(0.35%) among the 10,724 insureds of male, and in 22 cases(0.31%) among the 6,990 insureds of female. 3) The possessing rate of hemangioma in male was increased by age regardless of sex-5/2,120 cases(0.24%) in $21{\sim}30$ years, 25/8,122 cases(0.31%) in $31{\sim}40$ years, 16/4,997 cases(0.32%) in $41{\sim}50$ years, 8/1,775 cases(0.45%) in $51{\sim}60$ years, and 5/359 cases(1.39%) in over 61 years. 4) The tumor involved right lobe of the liver in majority(71.4%) 5) The size of tumor was 10 lesions in under 10 mm, 58 lesions in $31{\sim}50$ mm, and 6 lesions in over 51 mm. The smallest tumor was 8 mm in diameter and the largest was 72 mm in diameter and 78 lesion(92.8%) were less than 50 mm in size. 6) Posterior acoustic enhancement was noted in 4 lesions among 68 lesions of less than 30 mm in long diameter, and in 4 lesions among 16 lesions more than 30 mm in long diameter. 7) Echographically most of the lesions presented as a round or oval high homogeneous echogenic mass, although a few mass appeared to be hypoechoic or Mixed echogenic. Finally a small round echogenic, sharply-marginated and internally homogeneous lesion is highly suggestive of hemangioma. If the hypoechoic lesion has homogeneous internal echoes and/or strong marginal echoes, it is also suggestive of hemangioma.

The usefulness of $^{99m}Tc-labeled$ RBC single photon emission CT (SPECT) scanning in the diagnosis of hepatic heminagiomas was evaluated in 22 patients with various focal hepatic lesions including 15 cases of hemangiomas, 3 cases each of hepatomas and metastasis and 1 case of abscess. The diagnoses were based on ultrasonography and/or CT scanning, clinical stability of lesion for at least 6 months or surgical exploration. Seven cases of 15 hemangiomas were detected by delayed planar RBC scanning, whereas 4 cases were detected by delayed RBC-SPECT scanning. The smallest hemangioma shown by delayed RBC-SPECT scanning was 1.0 cm in diameter. compared with 2.2 cm by planar RBC scanning. One small hemangioma (2.0 cm) located adjacent to the heart was not found by either method. The sensitivities in detecting the hemangioma according to the site by planar imaging were 16.6% $(1.0\sim1.9cm)$, 66.7% $(2.0\sim2.9cm)$ and 83.3% (more than 3.0 cm) and by SPECT were 50.0%, 66.7% and 100%, respectively. Seven cases of non-hemangiomatous lesions did not show any significant increase in activity in the delayed blood pool images. It is concluded that $^{99m}Tc-RBC$ blood-pool SPECT scanning is clearly more sensitive in detecting small hemangioma than planar scanning and is, therefore, a choice of method for the detection of hepatic hemangioma.

간혈관종은 우리 몸에서 흔하게 발생하는 간병변 중 하나이다. 대부분 간혈관종은 증상이 없고 크기도 작기에 병리학적 검사로는 발견하기 어렵다. 따라서 간혈관종의 초기 발견 및 진단을 하기 위해서는 방사선 진단은 필수이다. 본 연구는 간혈관종에 대한 방사선진단인 전산화단층촬영, 자기공명영상, 핵의학, 초음파 검사의 방법에 대하여 연구하였다. 전산화단층촬영에서는 조영제를 이용한 삼중시기 기법, 자기공명영상 검사에서는 T1, T2 강조영상, 조영제를 이용한 동적 자기공명영상, 초고속 자기공명 영상기법, 확산강조영상의 방법, 핵의학에선 ^99mTc 표지 적혈구를 사용한 혈액풀 스캔방법, 초음파에선 색조도플러의 방법에 대해 연구하였다. 대부분의 간혈관종은 양성종양이기에 간세포암 등과 같은 악성 종양과 혼동하지 않게 주의하여 불필요한 시술을 방지해야 한다. 그러므로 정확한 진단을 하기 위해서는 간혈관종의 영상소견을 정확히 숙지하여 검사를 시행하는 것이 중요하다.
