Peliosis hepatis is a rare disease characterized by cystic hepatic sinusoidal dilatation and the presence of multiple blood-filled spaces in the hepatic parenchyma. In most cases, multiple lesions and individual cysts not exceeding 1cm in diameter occur. We report a case in which the condition occurred in a 33-year-old woman who presented with general weakness and in whom a 3.5 cm-sized single hepatic mass was discovered incidentally at ultrasonography. The radiologic features mimicked those of a signle hepatic mass.

Peliosis hepatis, an uncommon vascular condition, is characterized by multiple blood-filled cavities distributed throughout the liver. Computed tomography and magnetic resonance imaging findings of peliosis hepatis are nonspecific. A 40-year-old woman presented with multiple hepatic cystic masses. Two years later, the number and sizes of the masses had increased. We suspected metastatic hepatic disease and performed a liver biopsy. Histological examination revealed dilatation of hepatic sinusoids and multiple blood-filled cavities throughout the liver parenchyma. Thus, a diagnosis of peliosis hepatis was confirmed.

Peliosis hepatis is characterized by the presence in the liver of blood-filled cavities, which may or may not be lined with sinusoidal cells. The individual cysts or cavities usually do not exceed several centimeters in diameter. The cysts are typically continuous with adjacent, more normal sinusoids, and they sometimes can be seen in continuity with hepatic venous tributaries. The lesion is usually diagnosed by gross or microscopic examination. When suspected, it can be diagnosed by percutaneous liver biopsy. In the past, peliosis hepatis is primarily associated with wasting diseases, such as tuberculosis, malignancy, and chronic suppurative infection. However, recently peliosis hepatis is seen most commonly in association with the administration of anabolic steroids or HIV infection. We report a case of peliosis hepatis that is diagnosed by peritoneoscopic live biopsy and not associated with known disease.

Peliosis hepatis is a rare disease, resulting in blood filled spaces in the hepatic parenchyma. The authors report a case of peliosis hepatis associated with cholangiocarcinoma of the liver, and include a review of the literature. A 56-year-old man presented with febrile sensation and abdominal distention. Spiral CT showed an irregularly marginated mass, 4 cm in size and with peripheral enhancement, in the left lobe of the liver, which was enlarged ; its right hepatic lobe revealed inhomogeneous enhancement in portal dominant phase and homogeneous enhancement in the equilibrium phase. Pathologic reports revealed adenocarcinoma in the left lobe of the liver and peliosis hepatis in the right lobe.

Peliosis hepatis is an uncommon liver condition involving abnormal dilation of hepatic sinusoids, eventually leading to blood-filled cavities within the hepatic parenchyma. Although the pathogenesis is not understood fully, peliosis hepatis has usually been associated with the use of anabolic steroid therapy, oral contraceptives, various malignancies or tuberculosis. We report a case of 59-year-old patient with cholangiocarcinoma with peliosis hepatis. The patient was admitted for evaluation of abdominal pain and fever. Abdomen CT showed a round cytic and solid mass with peripheral duct dilatation in liver. Grossly, the spongy-like solid mass and cyst was noted. Microscopically, the solid mass was composed of tubular and solid adenocarcinoma in fibrotic stroma and a blood-filled cavity with dilated sinusoids was noted.

Peliosis hepatis is an uncommon condition of blood-filled cystic cavities in the liver. Although it is difficult to distinguish this condition from hepatic malignancy or abscess in computed tomography (CT), differential diagnosis is important because it doesn't need further evaluation or treatment such as liver biopsy or surgery. We report a case of peliosis hepatis in a patient with active pulmonary tuberculosis in hemodialysis patient. A 39-year-old man receiving hemodialysis for 3 months was admitted because of fever. Chest computed tomography (CT) showed multiple necrotic lymphadenopathies and nodular lesion in right upper lobe of the lung suggesting active pulmonary tuberculosis. Three low attenuated lesions were shown in both hepatic lobes in abdominal CT. Liver biopsy was performed. The histopathologic diagnosis of peliosis hepatis in the liver was made by a blood-filled space with fibrin and hemorrhage. After anti-tuberculosis therapy, hepatic low attenuated lesions disappeared.
