ABSTRACT
Twenty-three patients were prospectively examined with ultrasound (US) for acute or recurrent Achilles tendon symptoms. Three types of pathologic conditions of the Achilles tendon were found: tendinitis/tenosynovitis, acute tendon trauma, and postoperative changes. US appears to enable differentiation of these conditions and to contribute to the diagnosis of a broad range of Achilles tendon disorders.

Pelvic hematomas following prostatic biopsy are rare. We describe 2 cases of hematomas occurring in the prevesical space (space of Retzius) following transrectal biopsy. Computed tomography (CT) was useful in defining the extent of the hematoma and showing density changes related to the age and suppuration of the hematoma. While cystography has been used to diagnose prevesical hematomas, CT better assesses the size of the hematoma and changes that may occur over time.

Prenatal ultrasound has resulted in the earlier recognition of genitourinary-related abnormalities. This is a review for urologists of the normal developmental anatomy, physiology, and ultrasound characteristics of representative urogenital abnormalities with guidelines for diagnostic or therapeutic intervention.

Papillary renal cell carcinoma represents a separate clinicopathologic entity distinguished from nonpapillary renal cell carcinoma by angiography, microscopic pathology, and biological behavior. We correlated retrospectively 11 surgically proven papillary renal cell carcinomas with ultrasound patterns and gross pathologic findings. In addition, we reviewed retrospectively 65 surgically proven cases of nonpapillary renal cell carcinoma for sonographic patterns. Seven of 11 (64%) of the papillary tumors were less echogenic than the ipsilateral renal cortex (hypoechoic). Only 23% of the nonpapillary tumors were hypoechoic. These data suggest that renal papillary carcinoma tends to be hypoechoic on ultrasound. In most of the papillary cases, this hypoechoic pattern was due to a large central area of cystic necrosis within the tumor.

Thirteen patients with suspected extrathyroidal neck masses were investigated with the combination of fluorescent scanning and echography. Iodine content, the solid or cystic consistency of the lesion, and the position of the lesion with respect to the thyroid were determined preoperatively to estimate thyroidal origin and benignity or malignancy of the lesions. Pathologic diagnoses correlated well with these totally noninvasive studies of extrathyroidal neck masses.

When gallium is injected into a patient who has received many transfusions, the resultant scan appears similar to a bone scan with renal excretion. This case report presents a 51-year-old man with myelofibrosis and myeloid metaplasia. Gullium-67 and 52Fe scans with 99mTc-pyrophosphate bone scintigrams are included.

Five children with acute lymphocytic leukemia (ALL) developed encephalopathy following treatment with intrathecal or intraventricular methotrexate (MTX). In these patients computer assisted tomography was informative by revealing areas of decreased attenuation coefficient located periventricularly and in each centrum semiovale (three cases) and calcifications, mostly in the deep and cortical gray matter (two cases), as well as ventricular dilatation (four cases). Contrast injection used in one of these five patients, as well as in another child (not affected by ALL) with MTX encephalopathy, failed to reveal enhancement.
