Endoscopic ultrasound guided thrombin injection of angiographically occult pancreatitis associated visceral artery pseudoaneurysms: Case series.

Pseudoaneurysm is a known complication of pancreatitis associated with significant mortality and morbidity. Imaging plays an important role in the diagnosis and management. Computed tomography (CT) helps localize the lesion and the severity of the background pancreatitis but digital subtraction angiography with coil embolization is recommended to avoid bleeding and inadvertent surgery.

An Atypical Case of POEMS Syndrome with an Osteolytic Bone Lesion.

POEMS syndrome is a rare multisystem disorder with an underlying plasma cell dyscrasia associated with Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy and Skin changes. Usually it is associated with sclerotic bone lesions. It usually manifests in 5(th)-6(th) decade of life with a mean survival period of eight years.

Perfusion computed tomography in renal cell carcinoma.

Various imaging modalities are available for the diagnosis, staging and response evaluation of patients with renal cell carcinoma (RCC). While contrast enhanced computed tomography (CT) is used as the standard of imaging for size, morphological evaluation and response assessment in RCC, a new functional imaging technique like perfusion CT (pCT), goes down to the molecular level and provides new perspectives in imaging of RCC. pCT depicts regional tumor perfusion and vascular permeability which are indirect parameters of tumor angiogenesis and thereby provides vital information regarding tumor microenvironment.
