Renal cell carcinoma presenting as small bowel obstruction secondary to a metastatic ileal intussusception.

We report a rare clinical presentation of renal cell carcinoma in the form of small bowel obstruction which was secondary to a metastatic ileal intussusception. Intussusception in the elderly is most commonly due to an underlying neoplasm, however metastases from a renal cell carcinoma is very uncommon. We present clinical details, radiological and pathological findings of the case followed by a discussion of the diagnosis and management of intussusception in the adult population.

Esophagobronchial fistulae: Diagnosis by MDCT with oral contrast swallow examination of a benign and a malignant cause.

We report two cases of esophagobronchial fistulae diagnosed by Multi-detector computed tomography (MDCT) oral contrast swallow examination. It is helpful to supplement the CT study with an oral contrast swallow as it aids in confirmation of a suspected fistula and also demonstrates the fistula tract better. We present the clinical details and the imaging findings on MDCT of two cases of esophagobronchial fistulae - one secondary to chronic chest tuberculosis and the other secondary to a squamous cell carcinoma of the upper esophagus - followed by discussion of the etiology, pathogenesis, and imaging of these fistulae.
