A Case of Peliosis Hepatis Mimicking Metastatic Lesions of Increasing Size

Abstract

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.

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

“…In recent years, studies have shown that many new hepatic lesions in patients with underlying malignancy are not metastases ( 1 2 3 4 5 6 7 8 9 10 11 12 ). Several benign conditions frequently mimic metastasis in the patient during chemotherapy.…”

Peliosis Hepatis Shows Isometabolism on 18F-FDG PET/CT: Two Case Reports

“…PET/CT findings of PH is a Korean case report that mainly described the radiologic (US, CT, MRI) findings of PH and also included a PET image in which PH was also isometabolic [16]. PH is a rare vascular condition of the liver, characterized by cystic blood-filled cavities distributed randomly throughout the liver parenchyma.…”

“…Notwithstanding the many articles and reports on imaging findings of PH on computed tomography (CT), ultrasonography (US), and magnetic resonance imaging (MRI), the findings on 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT are not well known [16]. We report two cases of biopsy-proven PH, which enhanced-CT scans had initially suggested were liver metastases.…”
