Spontaneous internal hemorrhage of a giant hepatic hemangioma: A case report

Case Report: Spontaneous Rupture of Hepatic Hemangioma

Background

Hepatic hemangioma (HH) is a congenital vasal malformation that seemed like the most probable benign liver neoplasm, composed of masses of blood vessels, which are anomalous in arrangement and size. In most cases, HH is asymptomatic, and patients have an excellent prognosis. According to research, the location and size of the mass are correlated with the symptoms and complications. Reports of spontaneous rupture of HH have been less reported in the literature. In this emergency condition, dynamic contrast-enhanced CT scanning, especially triple-phase computed tomography (CT) with delayed imaging, is preferred.

Case Presentation

Here, we presented two middle-aged female patients with spontaneous rupture of HH in our hospital. Following an accurate diagnosis of enhanced CT and emergency surgery, patients recovered well and were discharged from the hospital.

Conclusion

Appropriate imaging studies, especially enhanced CT, and emergency surgery are indispensable for patients with spontaneous rupture of HH. As a surgeon, we need to pay attention to the asymptomatic patient with HH.

Giant Hepatic Hemangioma Causing Prolonged Fever and Indicated for Resection

Hepatic hemangiomas are benign liver tumors, and most of them progress asymptomatically. We report a case of hepatic hemangioma considered the cause of fever. A 53-year-old woman had a fever of 40°C for about 3 months without infection. Hepatic hemangiomas with internal bleeding of 10 cm in size on liver S8/7 and S3/2 were observed. These were resected laparoscopically for diagnostic treatment. She was afebrile after the operation. The pathological diagnosis was hematoma inside cavernous hemangioma. It should be noted that a bleeding hepatic hemangioma may cause fever of unknown origin and be indicated for resection.

Focal hepatic intrinsically hyperattenuating lesions at unenhanced CT: Not always calcifications

Due to the growing use of CT, there has been an increase in the frequency of detecting focal liver lesions. Intrinsically hyperattenuating hepatic lesions or pseudolesions are not uncommon at unenhanced CT. Hyperattenuating hepatic lesions can be divided into non-calcified and calcified. Causes of intrinsic hyperattenuation include hemorrhage, thrombosis, and calcifications. Focal liver lesions can show hyperattenuation on unenhanced CT in case of severe liver steatosis. Recognition of etiologies associated with hyperattenuation on unenhanced CT can help the radiologist in characterizing focal liver lesions and pseudolesions. In this paper, we describe the spectrum of intrinsically hyperattenuating focal liver lesions and pseudolesions at unenhanced CT.

Spontaneous internal hemorrhage of a giant hepatic hemangioma with infection: a case report and literature review

Spontaneous internal hemorrhage from a hepatic hemangioma is rare. This case describes a 59-year-old woman who was hospitalized with recurrent cough and fever for 6 months. The doctor thought that she had pneumonia, but other infectious diseases could not be ruled out. Therefore, related tests were performed and strong antibiotics were used, but the symptom of fever was persistent and recurred. Enhanced computed tomography (CT) findings showed a right hepatic giant hemangioma with hemorrhage, while tuberculosis, liver abscess, and immune disease were excluded by the physician. Because the patient’s fever was associated with a large hepatic hemangioma, the patient was transferred to surgery. During treatment, the amount of bleeding increased, so she underwent a right hepatic hemangioma resection in the emergency department. Her postoperative fever symptoms subsequently resolved. Pathological examination confirmed hemorrhagic necrosis with infection in hepatic hemangioma. Follow-up showed that the patient was afebrile.

Spontaneous intracapsular hemorrhage of a giant hepatic cavernous hemangioma: a rare case report and literature review

Background

Hepatic cavernous hemangioma is the most common type of benign liver tumor. Although ruptures and hemorrhages of hepatic hemangioma are rare complications, they are associated with high mortality. Most practitioners only pay more attention to abdominal hemorrhages caused by the rupture of hepatic hemangiomas. However, spontaneous intracapsular hemorrhages can often be neglected and poorly understood.

Case presentation

A 65-year-old man was referred to our institution with right upper quadrant pain, which had occurred suddenly and without a history of recent trauma. The blood test results were normal. Magnetic resonance imaging (MRI) of the abdomen showed a cystic mass in the right liver lobe. Considering the possibility of hepatic cystadenoma with hemorrhage, the patient underwent a right hepatic lobectomy. The pathological findings unexpectedly revealed intratumoral hemorrhage of hepatic hemangioma. The patient recovered well and was discharged eight days after surgery.

Conclusions

Intracapsular hemorrhage of hepatic cavernous hemangioma is challenging to diagnose and has a high potential risk of rupture. MRI is beneficial for diagnosing subacute internal hemorrhage cases, and it is recommended to undergo surgery for patients with a definitive diagnosis.

Spontaneous Rupture of a Hepatic Cavernous Hemangioma: A Rare Case of Sudden Unexpected Death

Cavernous hemangiomas represent the most common benign tumors affecting the liver. They are more often asymptomatic and usually diagnosed through radiological examinations performed for other reasons. When there are symptomatic, they may cause digestive disorders such as abdominal pain, nausea, vomiting, or a palpable mass. Sudden death may occur as a result of rupture and bleeding. Spontaneous rupture of cavernous hepatic hemangioma is a rare complication, but the mortality rate is high. We report a rare case of sudden unexpected death of a 46-year-old woman due to a spontaneous rupture of a giant hepatic cavernous hemangioma discovered at autopsy.

Spontaneous rupture of giant hepatic hemangioma: misdiagnosis as gastrointestinal perforation

Hepatic hemangioma is a frequent nonmalignant tumor in the human liver. Although rupture of hepatic hemangioma is a rare complication, it may have serious consequences. In this report, we describe a 56-year-old woman who underwent laparoscopic surgery and open surgery for sudden abdominal pain and peritonitis. Gastrointestinal perforation was prioritized before surgery according to the patient’s symptoms, signs, and radiological report. A giant dark red mass connected to the left liver by a pedicle was unexpectedly found during intraoperative exploration. Hemoperitoneum was also found. Conversely, no gastrointestinal perforation was found during intraoperative exploration. The mass was successfully removed, and the hemoperitoneum was resolved. Postoperative pathological examination showed that the mass was a hepatic hemangioma. Ultimately, the patient was diagnosed with spontaneous rupture of a giant hepatic hemangioma.

Fever of unknown origin: a rare presentation of giant hepatic hemangioma

Hepatic hemangioma is mostly asymptomatic and incidental finding on imaging. Fever of unknown origin as a sole presentation is rare. We present an interesting case report of a 49-year-old female, who presented with fever for three months. Extensive blood investigations and infectious workup failed to reveal the cause. Contrast computed tomography of abdomen revealed a giant (15 × 11 cm) hemangioma arising from left lateral segment of liver, and was attributed as a cause for fever. Surgical excision of hemangioma completely ameliorated the fever.
