Esophageal stricture assessment by esophagogram: A pictorial review of differential diagnosis

The purpose of this article is to review the most frequent conditions associated with esophageal strictures on esophagogram. The most common causes include caustic ingestion, radiation therapy, malignancy, extrinsic compression, gastroesophageal reflux disease, infectious esophagitis, systemic diseases and membranes and rings. Adequate characterization of the stricture is necessary for formulation of the best diagnostic hypothesis and can be used to distinguish between malignant and non-malignant conditions.Keywords: Esophageal diseases; esophageal stenosis; esophagus; esophageal neoplasms; esophageal achalasia; radiography; radiology; radiotherap

Pancreatic collision tumor : mucinous cystadenoma and clear cell renal cell carcinoma metastasis

We present a clinical, radiological, surgical, and pathological correlation case of a 49-year-old woman with a prior nephrectomy due to a clear cell renal cell carcinoma, who was then diagnosed with a multilocular cystic lesion in the pancreatic tail after a routine ultrasound. Computed tomography and magnetic resonance cholangiopancreatography showed a multilocular cystic lesion with a hypervascular wall nodule in the pancreas. The patient underwent a distal pancreatectomy and had a final diagnosis of pancreatic mucinous cystadenoma with an associated component of clear cell renal cell carcinoma (collision tumor of the pancreas)

Pancreatic collision tumour: mucinous cystadenoma and renal clear cell carcinoma metastasis.

We present a clinical, radiological, surgical and anatomopathological correlation case of a 49-year-old female with a prior nephrectomy due to a clear cell renal cell carcinoma (RCC), who discovered a multilocular cystic lesion in the pancreatic tail after a routine ultrasound. Computed tomography and magnetic resonance cholangiopancreatography were performed, showing a multilocular cystic lesion with a hypervascular wall nodule in the pancreas. The patient underwent distal pancreatectomy, with a final diagnosis of pancreatic mucinous cystadenoma with an associated component of clear cell renal cell carcinoma (collision tumor of the pancreas)
