This article presented readers with typical enhanced CT and MR images of a patient with epithelioid hemangioendothelioma, and briefly described the pathological mechanisms behind the typical imaging signs, in order to enhance the readers’ understanding and awareness of the typical imaging signs of this rare disease, and thus reduce its underdiagnosis rate and misdiagnosis rate.
Inflammatory myofibroblastic tumor (IMT) occurring in the pancreas was rare and few clinical cases had been reported. The specificity of clinical presentation of IMT was lacked and its CT imaging manifestations were diverse. The enhanced CT images of a rare patient with IMT of the pancreas with liver metastases were presented to the readers, and the pathophysiological mechanisms associated with the CT imaging manifestations were briefly described, so as to enhance the readers’ understanding and knowledge of the CT imaging manifestations and raise the diagnostic awareness of the disease.
Inflammatory myofibroblastic tumor (IMT) involving stomach, liver, biliary tract, and peritoneal mesentery was very rare, nonspecific clinical manifestations and laboratory examination were the main reasons for the difficult preoperative diagnosis of IMT. An IMT case involving multiple systems and multiple sites of the abdomen was presented, the CT and MRI imaging signs and pathological basis of IMT were illustrated, so as to strengthen the understanding of IMT for clinicians and radiologists.
Hepatoid adenocarcinoma (HAC) of the pancreas is a rare, highly malignant tumor with poor prognosis. This article presents the CT and MR features of HAC of the pancreas, while also reviewing the relevant literatures to succinctly summarize the underlying pathophysiological mechanism, imaging diagnosis, and differential diagnosis. The objective is to enhance the understanding of HAC of the pancreas among clinicians and radiologists.
With the development and popularization of imaging technology, the discovery of gallbladder lesions has become common, among which non-neoplastic lesions (such as gallbladder stones, cholecystitis, gallbladder polyps, gallbladder adenomyosis, etc.) are common but sometimes the imaging manifestations are not specific, and there are many kinds of such diseases, so accurate imaging diagnosis is still quite challenging. Familiarity and understanding of the typical imaging manifestations of these diseases will help to improve the early and accurate diagnosis and help to distinguish them from gallbladder malignant diseases, which is of great significance to the diagnosis, guiding treatment and prognosis of patients.
Carney triad is a rare tumor syndrome with few reports. This case showed the enhanced CT and MRI images of a rare young woman patient with Carney triad (containing gastric stromal tumor, renal cell carcinoma, adrenal pheochromocytoma, and pulmonary chondrosarcoma), which is intended to provide a reference for clinical diagnosis and differential diagnosis. This case reminds the radiologists and clinicians that the patients with a history of primary gastrointestinal stromal tumor and neoplastic lesions occurring at specific sites (pulmonary chondrosarcoma, adrenal pheochromocytoma, renal cell carcinoma, etc.) need to be alerted to the possibility of combining with Carney triad.
Lymphoma originating in the liver is rare and few clinical cases had been reported. The imaging manifestations of primary hepatic lymphoma (PHL) were lack of specificity and diverse. The authors displayed the CT and MRI images of one patient with diffuse infiltrating PHL and made a brief description of imaging features, underlying pathophysiological mechanisms, and differential diagnoses of PHL, with the hope of strengthening the understanding of PHL for clinicians and radiologists.
