a 65 year old male with metastatic colorectal cancer (mcrc) in the liver was referred for selective internal radionuclide therapy (sirt) following a history of extensive systemic chemotherapy. 90y pet imaging was performed immediately after treatment and used to confirm lesion targeting and measure individual lesion absorbed doses. lesion dosimetry was highly predictive of eventual response in ...

The aim of the study is to evaluate the contrast enhanced power doppler technique as a method to detect and differentiate vascular patterns of focal liver lesions. Fourty-nine patients with focal liver lesions were included in the study, twenty-nine of them with malignant liver lesions (9 HCC, 20 metastatic), twenty patients with benign lesions (12 haemangiomas, 5 focal nodular hyperplasia, 3 f...

RATIONALE Peliosis hepatis (PH) is a rare tumor-like liver lesion composed of multiple blood-filled cavities within the liver parenchyma. It is hard to differentiate PH from other liver lesions by imaging, such as carcinoma, metastases, or abscess. PATIENT CONCERNS Here, we reported 2 cases that presented with liver lesions under ultrasound and computed tomography (CT) scanning, without any h...

BACKGROUND Caudate lobe liver metastases occur commonly in patients with neuroendocrine tumors. It is unknown, however, how these lesions respond to regional therapy and how their presence impacts outcomes. We reviewed our experience treating these lesions using transarterial chemoembolization (TACE). METHODS We reviewed radiographic response to TACE in 86 patients with metastatic neuroendocr...

We report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. Thorax, abdomen and pelvis Contrast-Enhanced Computed Tomography (CECT) showed lymph nodes, spleen and liver lesions. Axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (MZL) at stage IV was postulated, then the p...

Introduction: Hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mTc- RBC scan is highly specific and is the method of choice for this differentiation. This scintigraphy is performed in Planar and SPECT modes. These two procedures are in agreement most of the times, however since SPE...

OBJECTIVES To evaluate the added value of the application of the liver-specific contrast phase of Gadobenate dimeglumine (Gd-BOPTA) for detection and characterization of liver lesions in 18F-FDG PET/MRI. METHODS 41 patients with histologically confirmed solid tumors and known / suspected liver metastases or not classifiable lesions in 18F-FDG PET/CT were included in this study. All patients u...

Von Meyenburg complexes (VMC) are a cluster of benign liver malformations including biliary cystic lesions, with congenital fibrocollagenous stroma. This rare entity can mimick multiple secondary hepatic lesions. We report a case of a 56-year-old woman who had multiples liver lesions 12 years after operation for breast cancer. Biopsy of the hepatic lesion confirmed the diagnosis of VMC. Preoper...

Modern cross-sectional imaging with multidetector computed tomography (MDCT) or magnetic resonance imaging (MRI) often reveals small focal liver lesions, which puts pressure on the reporting radiologist to characterize these tiny lesions. On the other hand, in patients with underlying diffuse liver disease, such as cirrhosis or severe steatosis, the detection of focal liver lesions can be quite...
