Catheter fracture and migration into the coronary sinus--an unusual migration site: case report and review.

Catheter fracture and cardiac migration are rare but known complications. Most reported cases have developed between the clavicle and the first rib as a consequence of catheter pinching between these two bony structures. To our knowledge, this is the first reported case of catheter migration into the coronary sinus.

Massive gastric dilatation after a single binge in an anorectic woman.

Objective: Massive gastric dilatation is a very serious condition that is extremely rare in patients with no history of gastrointestinal disease. Several cases have been reported in patients with eating disorders, particularly after a binge. We report here the case of a young woman who developed severe gastric dilatation after a single binge.

Imaging of common benign solid liver tumors.

The imaging modalities currently used for radiologic detection and characterization of hepatic neoplasms include color Doppler sonography, helical computed tomography (plain, biphasic enhanced CT), magnetic resonance imaging (plain, gadolinium enhanced MR), radionuclide scintigraphy (Technetium RBC, sulfur-colloid, IDA scan), angiography, and image-guided percutaneous needle biopsy. MR imaging is probably better at characterizing lesions than CT scan, but the latter remains the modality of choice at many institutions due to the speed of acquisition and good contrast resolution inherent in the technique. Each of these modalities is useful, but accurate lesion detection and specific radiologic diagnosis is most often made in many patients with typical imaging features using a combination of examinations rather than with a single modality.

Radiology of perinephric fluid collections.

The perinephric spaces consist of the subcapsular, perirenal, anterior and posterior pararenal spaces. Fluid may collect in one or more of these compartments; this can be readily demonstrated by cross-sectional imaging, particularly computed tomography (CT). This pictorial review illustrates the radiological manifestations of perinephric fluid collections with their differential diagnosis including perinephric abscess, perirenal urine collection, subcapsular and perirenal hematoma, renal lymphangiomatosis, pancreatic pararenal fluid collections and transudate fluid associated with nephropathies.
