“…The tumors that most commonly metastasize to the pancreas are melanomas, lymphomas and carcinomas of the kidney, lung, breast and colon [9,18]. The bizarre presentation of secondary metastases to the pancreas, such as being either solid or cystic, hypo- or hyperdense on computed tomography images [19], and being single rather than multiple masses, leads to their frequent misdiagnosis [16,18,20]. …”

“…This may be explained by relative hypervascularity of the normal pancreatic parenchyma. Pancreatic metastases from RCC, which is the most common primary tumor to metastasize to the pancreas [2,4] , are usually hypervasuclar [17] . Surgical resection of pancreatic metastasis is a relatively safe and useful procedure.…”

AIM:To describe the multidetector computed tomography features of pancreatic metastasis from leiomyosarcoma (LMS). METHODS:Between January 1995 and December 2012, 13 consecutive patients (11 women, 2 men; mean age of 57 years; range, 38-78 years) with pancreatic metastases from LMS were included in our study. Imaging features including location, number, largest dimension, tumor attenuation and enhancement characteristics, presence of necrosis, pancreatic ductal dilatation, common bile duct (CBD) dilatation, presence of pancreatitis, and atrophy were documented. RESULTS:The most common site of origin of the pancreatic metastases from LMS was uterus (38.5%), followed by retroperitoneum (30.8%) and extremity (23.1%). None of the patients in our study had pancreas as the first site of metastasis. All patients developed pancreatic metastases at a median interval of 24 mo. Pancreatic metastases from LMS were solitary in 8/13 patients and multiple in 5/13 patients, had no predilection for any part of the pancreas, were hypovascular on arterial phase in 10/13 patients and associated with pancreatic duct dilatation in 3/13 patients. None had CBD dilatation. None of the pancreatic metastases in LMS cohort caused pancreatitis, and atrophy. Median duration of follow-up was 19 mo for LMS cohort during which two patients underwent resection of metastasis (median survival 45 mo) while the remaining underwent systemic therapy (median survival 13 mo). ORIGINAL ARTICLE CONCLUSION:Pancreatic metastases from LMS are often solitary and hypovascular masses and less commonly associated with pancreatic ductal dilatation, CBD dilatation, pancreatitis or pancreatic atrophy. Surgical resection of solitary LMS pancreatic metastasis can be considered due to the long survival of these patients. Core tip: Pancreatic metastases from leiomyosarcoma (LMS) commonly arise in the uterus and are characterized by a long latency period after the diagnosis of primary tumor. Although the imaging features of the pancreatic metastases from LMS are nonspecific, pancreatic metastases from LMS should be considered in the differential diagnosis of solitary or multiple hypovascular masses without pancreatic ductal dilatation, common bile duct dilatation, pancreatitis, atrophy in the pancreas in patients with history of LMS. Surgical resection of solitary LMS pancreatic metastasis can be considered due to the long survival of these patients after detection of pancreatic metastasis.Suh CH, Keraliya A, Shinagare AB, Kim KW, Ramaiya NH, Tirumani SH.

“…Las metástasis pancreáticas pueden presentarse como tumores sólidos, lesiones quísticas o lesiones hiperdensas o hipodensas en la TC 6,16 . Generalmente son lesiones bien delimitadas, redondeadas y que tras la inyección de contraste presentan un comportamiento hipervascular con realce intenso y homogéneo (en lesiones pequeñas) o realce periférico (en las de mayor tamaño) 17 . No obstante, según algunos autores, el realce puede ser intenso y heterogéneo 18 .…”
