“…Common presentations include ulcerations, polypoid mass, lymphadenopathy, diffuse or focal thickening of the gastric wall and even no changes in the gastric structure. Gastric lymphomas should be differentiated from peptic ulcers, hypertrophic gastritis and other gastric malignancies . 18 FDG‐PET is not useful in the diagnosis of primary gastric lymphomas due to the low activity of FDG in the stomach.…”

Primary gastrointestinal (GI) lymphomas are uncommon diseases that can involve the whole GI tract. The etiologies of the disease remain unclear, and potential risk factors include celiac disease, Helicobacter pylori infection, use of immunosuppressive agents, human immunodeficiency virus (HIV) or Epstein-Barr virus (EBV) infection and inflammatory bowel disease, etc. Diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue (MALT) lymphoma are the most common subtypes of GI lymphomas. B-cell lymphomas of the GI tract are more common in Western countries, while in Asia-Pacific region T-cell lymphomas are more frequently reported. In this review, lymphomas in the esophagus, stomach and intestine are described, including their epidemiology, histology, clinical manifestations, endoscopic findings, radiological features and treatment.

“…The diffuse large B-cell lymphoma (DLBCL), rare T-cell lymphoma, or NK-cell lymphoma are less common. The occurrence of MZBCL has been observed in about 8% of pSS patients; it is 40 times higher than in the healthy population [21,22].…”

CT, MRI, and 18F-FDG PET/CT Findings in Untreated Pulmonary and Hepatic B-Cell Lymphoma of Mucosa-Associated Lymphoid Tissue (MALT) Over a Five-Year Period

et al. 2016

Imaging findings of hepatic lymphoma of mucosa-associated lymphoid tissue (MALT) have been rarely reported before. We present the computed tomography (CT), magnetic resonance imaging (MRI), and fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT findings in a patient with untreated pulmonary and hepatic MALT lymphoma over a 5-year period.On the 1st abdominal MRI scan, the hepatic MALT lymphoma showed multiple hepatic subcapsular masses. On FDG PET/CT, these hepatic tumors showed hypodenisty with FDG uptake similar to the liver on early PET images, and higher than liver on delayed PET images. The patient declined to undergo treatment. Fiver year later, the follow-up MRI and FDG PET/CT showed enlargement and confluence of the hepatic tumors with higher FDG uptake than before. The enlarged hepatic tumors had minimal mass effect. In the hepatic lesions, the blood vessels and bile ducts had no distortion or displacement.The hepatic MALT lymphoma should be taken into consideration when the hepatic tumors have minimal mass effect with the intrahepatic blood vessels and bile ducts normally passing through the tumors. Delayed-time-point FDG PET/CT imaging may be helpful for improving detectability of the hepatic MALT lymphoma.

Mucosa-Associated Lymphoid Tissue Lymphoma: Multimodality Imaging and Histopathologic Correlation

Abstract: Differences in clinical behavior and management make it exceedingly important to differentiate MALT lymphoma from other types of lymphomas. Radiologic and histopathologic findings need to be taken into account before making a diagnosis and treatment plan.
