ABSTRACT: Afferent loop obstruction is a relatively rare but significant complication of Billroth II gastrojejunostomy. We report the imaging findings in a patient in whom obstruction presented acutely and was due to the presence of an enterolith. CT showed dilatation of both the main pancreatic duct and the biliary ducts, and a markedly dilated afferent loop within which a 5-cm mass was present. The lesion had a heterogeneous, laminated appearance and did not show any contrast enhancement. Edema of fatty tissues surrounding the pancreatic tail, which extended to the left pararenal spaces, a small amount of free peritoneal fluid surrounding the spleen, and an aneurysm of the splenic artery of about 3 cm were also present. The diagnosis of afferent loop obstruction has to be considered in patients with previous Billroth II gastrojejunostomy who present with acute abdominal pain and laboratory findings indicating pancreatitis. Although rarely, an enterolith can be the cause of obstruction. CT allows to establish the diagnosis.

ABSTRACT: Epidermoid cysts of the testis are rare benign lesions, without malignant potential, that can be managed conservatively with cyst enucleation and testis-sparing surgery. Bilateral epidermoid cysts in the testes have been reported very infrequently. We report the sonographic and MRI findings in a patient who presented with a palpable nodule in only 1 testis, but in whom sonography showed bilateral lesions. On sonography, the cysts had an internal "onion-ring" structure; color Doppler signals were absent. On MRI, the cysts had a laminated appearance, with alternating low- and high-signal-intensity areas on T2-weighted images. These imaging findings and the negative results of laboratory tests for tumor markers suggested the correct diagnosis, and testis-sparing surgery could be performed.

ABSTRACT: The progressive refinement of broadband transducers with frequencies higher than 10 MHz and improved near-field resolution has enhanced the potential of sonography to evaluate a variety of nerve entrapment syndromes occurring in the upper limb, such as suprascapular neuropathy in the area of the spinoglenoid-supraspinous notch, the quadrilateral space syndrome (axillary neuropathy), radial neuropathy in the area of the spiral groove, the supinator syndrome (posterior interosseous neuropathy), the cubital tunnel syndrome (ulnar neuropathy), and the Kiloh-Nevin syndrome (anterior interosseous neuropathy). In these settings, high-resolution sonography can depict changes in the nerve's shape and echotexture and can depict many extrinsic causes of nerve entrapment.
