Peliosis Hepatis and Iron Deficiency – An Interesting Case Report

Peliosis hepatis (PH) is a rare condition showing presence of multiple blood-filled cystic cavities in the liver. It does not have any gender predilection, and is suspected to be idiopathic. However, in patients with predisposing diseases, its prevalence can range from 0.2 to 22%. The association between PH and anemia has not been completely established. PH has been reported in a patients with hematologic disease, and also in patient with spherocytic haemolytic anemia. It is also suggested that acute sequestration of blood can happen in these sinusoidal cavities, which can lead to development of anemia and thrombocytopenia. We present a case of 40-year female who presented with abdominal pain and recurrent iron deficiency anemia. On examination, she was severely pale, and had moderate hepatosplenomegaly. Ultrasonography showed hepatomegaly and splenomegaly, and her blood investigations revealed severe iron deficiency with bone marrow showing hypercellular marrow with depleted iron stores. Upper gastrointestinal endoscopy was normal. Liver biopsy showed changes suggestive of peliosis hepatis. She was treated with iron andmultiple blood transfusions and is in good health 6 months post presentation. Also, the association between anemia and PH has not been established

MRI features to differentiate between peliosis hepatis and hepatic metastases following chemotherapy for gastrointestinal adenocarcinoma / 中华肝胆外科杂志

Objective@#To compare the MRI features of peliosis hepatis and hepatic metastases following chemotherapy for gastrointestinal adenocarcinoma with the aim to improve the differential diagnosis.@*Methods@#The clinical data of 33 patients with gastrointestinal adenocarcinoma treated from June 2014 to December 2017 at Zhongshan Hospital of Fudan University were retrospectively analyzed. Of the 26 males and 7 females aged (56.0±9.8) years, there were 11 patients with peliosis hepatis and 22 patients with hepatic metastases following chemotherapy in these patients. All patients underwent contrast-enhanced abdominal MRI scans. The differences in the MRI features, including morphology, margin, signal intensity on plain scanning and enhancement patterns were compared statistically. The apparent diffusion coefficient (ADC) values of peliosis hepatis, hepatic metastases and adjacent hepatic parenchyma were measured in an ADC map.@*Results@#In 14 lesions of the 11 patients with peliosis hepatis, 10 lesions were ill-defined and 4 lesions were well-defined. In 31 lesions of the 22 patients with hepatic metastases, 5 lesions were ill-defined and 26 lesions were well-defined. Significant differences existed between peliosis hepatis and hepatic metastases in the margin (P<0.05). The ADC value of hepatic metastases was significantly lower than that of peliosis hepatis and the adjacent hepatic parenchyma (P<0.05). In all the 14 lesions of peliosis hepatis, 10 lesions showed gradual filling enhancement, and 4 lesions showed marked and persistent enhancement. In all the 31 lesions of hepatic metastases, 28 lesions showed a ring-shaped enhancement, and 3 lesions showed "quick in and quick out" enhancement.@*Conclusions@#The lesions of peliosis hepatis following chemotherapy for gastrointestinal adenocarcinoma were ill-defined, with no restriction of water diffusion in the diffusion weighted imagings, and with progressive enhancement. The MRI manifestations of peliosis hepatis helped to differentiate peliosis hepatis from hepatic metastases of gastrointestinal adenocarcinoma.

Peliosis hepatis and systemic lupus erythematosus: A rare condition identified by magnetic resonance imaging / Peliose hepática e lúpus eritematoso sistêmico: uma rara condição identificada pela ressonância nuclear magnética

Summary Peliosis hepatis is a rare benign disorder characterized by the presence of multiple cavities filled with blood with no preferential localization in the liver parenchyma. It may be related to several etiologic conditions, especially infections and toxicity of immunosuppressive drugs. To our knowledge, there are only three articles reporting the association between peliosis hepatis and systemic lupus erythematosus. In this report, we describe a case of this rare condition, highlighting the importance of magnetic resonance imaging. A short review of this subject is also presented.

Resumo Peliose hepática é uma patologia benigna rara caracterizada pela presença de múltiplas cavidades preenchidas por sangue sem localização preferencial no parênquima do fígado. Pode estar relacionada a uma série de condições etiológicas, dentre elas doenças infecciosas e toxicidade por drogas imunossupressoras. Para nosso conhecimento, existem apenas três artigos que abordam a associação entre peliose hepática e lúpus eritematoso sistêmico. Neste relato, descrevemos um caso desta rara condição, destacando a importância da ressonância magnética. Uma breve revisão sobre o tema é apresentada.

MRI features of peliosis hepatis / 中华放射学杂志

Objective To investigate the MRI features of peliosis hepatis (PH).Methods Nine patients with pathologically proven PH were retrospectively included.Plain scan and contrast-enhanced MRI of the abdomen were performed on all patients before operation.All clinical,pathological and MR imaging data of patients were collected.The MR image analysis of the lesion included the number,location,size,shape,lesion margins,signal intensity,and enhancement pattern.Results Eleven lesions were detected in 9 patients,with 10 lesions in the right lobe of the liver and 1 lesion in the left lobe.The maximum diameter of the 11 lesions was 0.7 cm to 8.8 cm (mean 3.7 cm).All 11 lesions were round or oval in the shape.Seven lesions had clear boundaries and 4 lesions had blurred boundaries.Signal intensity of 2 lesions were homogeneous,while 9 lesions had heterogenous signal intensity on plain san.Ten lesions showed slightly hypointense on T1WI,slightly hyperintense on T2WI and mildly progressive enhancement.These lesions were weakly enhanced and showed slight cluster-like mild enhancement in the arterial phase.The enhancement scope of the lesions gradually filled into the interior in the portal vein phase and the signal intensity was slightly higher than liver in delay phase.One lesion showed hypointense on T1WI and hyperintensity on T2WI.After the enhancement,the lesion was evenly enhanced and showed continuous enhancement.On DWI,11 lesions were slightly hyperintense.The signal intensity of 9 lesions were equal to that of the liver,and the signal intensity of the 2 lesions was slightly higher than that of the liver on the ADC map.Conclusion MRI signs of PH have certain characteristics,which can help diagnosis and differential diagnosis.

Hepatic Lesions that Mimic Metastasis on Radiological Imaging during Chemotherapy for Gastrointestinal Malignancy: Recent Updates

During chemotherapy in patients with gastrointestinal malignancy, the hepatic lesions may occur as chemotherapy-induced lesions or tumor-associated lesions, with exceptions for infectious conditions and other incidentalomas. Focal hepatic lesions arising from chemotherapy-induced hepatopathies (such as chemotherapy-induced sinusoidal injury and steatosis) and tumor-associated eosinophilic abscess should be considered a mimicker of metastasis in patients with gastrointestinal malignancy. Accumulating evidence suggests that chemotherapy for gastrointestinal malignancy in the liver has roles in both the therapeutic effects for hepatic metastasis and injury to the non-tumor bearing hepatic parenchyma. In this article, we reviewed the updated concept of chemotherapy-induced hepatopathies and tumor-associated eosinophilic abscess in the liver, focusing on the pathological and radiological findings. Awareness of the causative chemo-agent, pathophysiology, and characteristic imaging findings of these mimickers is critical for accurate diagnosis and avoidance of unnecessary exposure of the patient to invasive tissue-based diagnosis and operations.

Peliosis hepatoesplénica por enfermedad por arañazo de gato. Reporte de caso / Hepatosplenic peliosis by cat scratch disease: report of a case

Se presenta el caso de una paciente mujer de 73 años que acude por disnea progresiva, fiebre diurna, hiporexia y cefalea de diez días de evolución. Antecedente de neoplasia ovarica, gastritis crónica y tromboembolia pulmonar. La fiebre continuó a pesar de tratamiento antibiótico convencional. Al examen, se identificó compromiso pulmonar y adenopatías inguinales, estas últimas corroboradas por ecografía de partes blandas. Los cultivos realizados fueron negativos y el estudio radiológico mostró compromiso pleuroparenquimal en base de pulmón izquierdo. La tomogragía abdominal evidenció hepatoesplenomegalia con hipodensidades múltiples (peliosis); la serología fue compatible con Bartonella henselae. La paciente evolucionó favorablemente luego de 72 horas de iniciado en tratamiento con doxiciclina a 100 mg cada doce horas.

This is the case of a 73-year-old female patient who presented with progressive dyspnea, diurnal fever, hyporexia and headache lasting for 10 days. She had a past medical history of an ovarian neoplasia, chronic gastritis and pulmonary thromboembolism. Fever continued despite conventional antibiotic treatment. Her physical examination revealed pulmonary involvement and bilateral inguinal adenopathy; the latter was corroborated with soft tissue ultrasound. Cultures performed were reported as negative and a chest X-ray film showed pleuro-parenchymal involvement in the left pulmonary base. An abdominal CT scan showed hepatosplenomegaly with multiple hypodense images (peliosis); and serological studies were compatible with Bartonella henselae. Doxyciclin 100 mg every 12 hours was started, and the patient started recovering uneventfully 72 hours after therapy was instituted.

C3H/He Mice as an Incompatible Cholangiocarcinoma Model by Clonorchis sinensis, Dicyclanil and N-Nitrosodimethylamine

Clonorchis sinensis is a Group-I bio-carcinogen, associated with cholangiocarcinoma (CCA). The hamster is the only experimental model of C. sinensis-mediated CCA, but we oblige another animal model. The present study intended to develop a C. sinensis (Cs) mediated CCA model using C3H/He mice, co-stimulated with N-nitrosodimethyl-amine (NDMA) and dicyclanil (DC). The mice were divided into 8 groups with different combinations of Cs, NDMA, and DC. Six months later the mice were sacrificed and subjected to gross and histopathological examination. The body weights were significantly reduced among the groups treated with 2 or more agents (eg. Cs+NDMA, Cs+DC, NDMA+DC, and Cs+NDMA+DC). In contrast, liver weight percentages to body weight were increased in above groups by 4.1% to 4.7%. A Change of the spleen weight was observed only in Cs+NDMA group. Though C. sinensis infection is evident from hyperplastic changes, only 1 worm was recovered. T wo mice, 1 from Cs and the other from Cs+DC group, showed mass forming lesions; 1 (281.2 mm3) from the Cs group was a hepatocellular adenoma and the other (280.6 mm3) from the Cs+DC group was a cystic mass (peliosis). Higher prevalence of gray-white nodules was observed in Cs group (42.9%) followed by Cs+NDMA+DC group (21.4%). The mice of the Cs+NDMA+DC group showed hyper-proliferation of the bile duct with fibrotic changes. No characteristic change for CCA was recognized in any of the groups. In conclusion, C3H/He mice produce no CCA but extensive fibrosis when they are challenged by Cs, NDMA, and DC together.

Peliosis hepatis presenting with massive hepatomegaly in a patient with idiopathic thrombocytopenic purpura

Peliosis hepatis is a rare condition that can cause hepatic hemorrhage, rupture, and ultimately liver failure. Several authors have reported that peliosis hepatis develops in association with chronic wasting disease or prolonged use of anabolic steroids or oral contraceptives. In this report we describe a case in which discontinuation of steroid therapy improved the condition of a patient with peliosis hepatis. Our patient was a 64-year-old woman with a history of long-term steroid treatment for idiopathic thrombocytopenic purpura . Her symptoms included abdominal pain and weight loss; the only finding of a physical examination was hepatomegaly. We performed computed tomography (CT) and magnetic resonance imaging (MRI) of the liver and a liver biopsy. Based on these findings plus clinical observations, she was diagnosed with peliosis hepatis and her steroid treatment was terminated. The patient recovered completely 3 months after steroid discontinuation, and remained stable over the following 6 months.

Diagnosis and treatment of peliosis hepatis / 中华消化外科杂志

Peliosis hepatis is a rare benign hepatic vascular disease.There is the lack of specific clinical features and preoperative diagnosis.A patient with intermittent liver area pain was admitted to the Third Central Hospital of Tianjin in April 2014.The patient with space-occupying lessions of the right lobe of liver was preliminarily diagnosed as with hepatocellular tumor or vasogenic tumor by computed tomography and B ultrasound examinations and then received liver resection combined with cholecystectomy.The result of postoperative pathological examination confirmed peliosis hepatis with adenomatous hyperplasia of liver cells.The patient was followed up till October 20,2014 without recurrence.

Peliosis hepatoesplénica: informe de un caso y revisión de la literatura / Hepatosplenic peliosis: a case report and a literature review

La peliosis es una entidad benigna muy rara, que se caracteriza por cavidades repletas de sangre dentro de órganos sólidos, principalmente en el sistema reticuloendotelial. La peliosis puede también afectar otros órganos como pulmones, pleura, riñones, glándulas suprarrenales y estómago. Las lesiones pueden ser únicas o múltiples y de tamaño variable. La etiología es ignorada, pero se ha relacionado con la ingestión o contacto con fármacos y tóxicos diversos como esteroides y anticonceptivos orales, asociándose a enfermedades tumorales hematológicas y a enfermedades infecciosas, en particular a la tuberculosis; en algunos casos es idiopática. Presentamos el caso de una mujer de 60 años con antecedentes de hipertensión arterial. La exploración física y los estudios de imagen evidenciaron una hepatomegalia nodular gigante sin esplenomegalia. Los exámenes de laboratorio indicaron trastornos propios de insuficiencia hepática y la paciente fallece por shock hipovolémico y hemoperitoneo. El estudio necrópsico determinó la existencia de una peliosis hepatoesplénica parenquimatosa “mayor” de etiología idiopática. Se lleva a cabo una revisión de la literatura, señalando aspectos relacionados con historia, patogénesis, etiología, aspectos clínicos, diagnósticos y terapéuticos.

Peliosis is a very rare benign entity which is characterized by blood filled cavities filled within solid organs. They occur primarily in the mononuclear phagocyte system although peliosis can also affect organs such as the lungs, pleura, kidneys, adrenal glands and stomach. Only one lesion or multiple lesions may occur, and their size is also variable. The etiology is unknown but is related to ingestion of, or direct contact with, drugs and various toxic substances such as steroids and oral contraceptives. It is associated with hematologic cancers and infectious diseases, particularly tuberculosis. In some cases it is idiopathic. We present the case of a 60 years old woman with a history of hypertension. Physical examination and various imaging studies showed a giant nodular hepatomegaly without splenomegaly. Laboratory studies showed disorders due to liver failure. The patient finally died of hypovolemic shock and hemoperitoneum. An autopsy determined the presence of parenchymal hepatosplenic peliosis of other than idiopathic etiology. A literature review highlighting the history, pathogenesis, etiology, clinical aspects, diagnosis and treatment of hepatosplenic peliosis is included.

A Case of Peliosis Hepatis Mimicking Metastatic Lesions of Increasing Size

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 hepática focal: Caso clínico radiológico / Peliosis hepatis: Report of one case

Peliosis hepatis is a rare vascular condition of the liver characterized by the presence of cystic blood-fi lled cavities distributed randomly throughout the liver parenchyma. We report a 46 year old female, with dyspepsia. An abdominal Doppler ultrasound showed a hyper vascularized solid liver nodule of 5 cm diameter. Magnetic resonance imaging and CT scan showed the same hyper vascularized nodule. With the possible diagnoses of primary hepatocellular carcinoma or focal nodular hyperplasia, the patient was subjected to an excision of hepatic segment VI, where the nodule was located. The pathological diagnosis of the surgical piece was a peliosis hepatis.

Peliosis Hepatis Cured with Anti-tuberculosis Medication in a Hemodialysis Patient / 대한신장학회지

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.

Peliosis hepatis como complicación del uso de anticonceptivos orales en una paciente con mielodisplasia / Peliosis hepatis as a complication of the ise of oral contraceptives in a patient with myelodysplasia

Introduction: Peliosis hepatis (PH) is an uncommon condition in pediatrics; however, it is one of the most serious complications associated with the long-term use of use of steroids. It is characterized by multiple blood-filled cavities, mostly involving the liver. Myelodysplastic Syndrome (MDS) is also a complex and infrequent hematological condition; it may transform into acute leukemia and its treatment requires medications that may lead to PH. Case Report: 13 year-old girl with MDS, refractory cytopenia type. A family donor for SCL was not available, therefore immunosuppressive treatment, steroids and transfusions were initiated. Due to metrorrhage, estrogen was used at high doses. She developed acute abdominal pain; abdominal ultrasound and CL scan showed PH and peritoneal bleeding. Oral contraceptives were decreased resulting in reduction of PH, but a new episode of uterine bleeding causing hypovolemic shock forced a hysterectomy in order to suspend estrogen treatment. Due to lack of response to treatment to SMD, she continued been treated with transfusions as needed, and died 32 months post diagnosis. Discussion: PH is an uncommon and life-threatening condition in children receiving prolonged treatment with steroids. Current modalities of SCL in patients with MDS will replace the need for steroids, thus avoiding this severe complication.

Introducción: La Peliosis Hepática (PH) es una condición muy infrecuente en pediatría, caracterizada por la presencia de múltiples cavidades sanguíneas en el parénquima hepático, asociada al uso prolongado de estrógenos o corticoides, El Síndrome Mielodisplásico (SMD) es una alteración hematológica compleja que puede evolucionar a leucemia y que puede requerir para su tratamiento medicamentos relacionados al desarrollo de PH. Caso Clínico: Niña 13 años, con SMD tipo citopenia refractaria, con dependencia transfusional, sin posibilidad de realizar Trasplante de progenitores hematopoyéticos (TPH) por falta de donante familiar compatible. Recibió transfusiones, inmunosupresores y corticoides por tiempo prolongado. Presentó metrorragias severas requiriendo estrógenos en altas dosis. Evolucionó con hemoperitoneo, diagnosticándose PH por ecografía y scanner abdominal. Al reducir dosis de estrógenos disminuyeron lesiones hepáticas, pero nuevo episodio de metrorragia con shock hipovolémico, obligó a realizar histerectomía para suspender estrógenos. Sin respuesta a tratamiento del SMD, se mantuvo con transfusiones según requerimiento y falleció a los 32 meses del diagnóstico. Discusión: La PH es una complicación grave, que podría evitarse con el desarrollo de nuevas técnicas de TPH que permiten contar con donantes no relacionados para el tratamiento de síndromes de falla medular como el SMD.
