Clinical case report: discitis osteomyelitis complicated by inferior vena cava venous thrombosis and septic pulmonary emboli.

Viridans group streptococcus is an infrequent cause of osteomyelitis that is found in association with infective endocarditis. Only a few studies report viridans osteomyelitis in the absence of endocarditis. Vertebral pyogenic osteomyelitis can sometimes be complicated by psoas or paraspinal abscesses.

Gastroenteropancreatic neuroendocrine tumors: multimodality imaging features with pathological correlation.

Neuroendocrine tumors of the gastrointestinal tract are rare entities. Functioning neuroendocrine tumors tend to present early because of hormone-induced clinical symptoms, but detection of the primary lesion may be difficult owing to their small size. Neuroendocrine tumors are typically hypervascular and show enhancement after contrast administration on computed tomography (CT) or magnetic resonance imaging (MRI).

Complications of esophageal surgery: role of imaging in diagnosis and treatments.

Esophageal surgery is a common and integral component in the management of hiatal hernias, esophageal carcinoma, and esophageal perforation. Understanding the expected postsurgical imaging features of these common esophageal surgeries and postoperative complications is essential. Image-guided intervention can be used to aid the surgeon in the management of many post esophageal surgical complications.

Mucosa-associated lymphoid tissue lymphoma: multimodality imaging and histopathologic correlation.

Objective: We will illustrate the imaging features of gastrointestinal and nongastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma and their correlation with histopathologic findings. The radiologic features to distinguish gastrointestinal MALT lymphoma from other types of lymphomas will also be described.

Conclusion: Differences in clinical behavior and management make it exceedingly important to differentiate MALT lymphoma from other types of lymphomas.
