To assess and compare the clinical usefulness of transrectal ultrasound (TRUS), magnetic resonance imaging (MRI), and three-dimensional proton magnetic resonance spectroscopic imaging (3-D MRSI) in detecting local recurrence of carcinoma of the prostate (CaP) in patients with detectable prostate-specific antigen (PSA) levels after cryosurgery. ⋯ 3-D MRSI is superior to TRUS and MRI in differentiating among CaP, BPH, and necrosis when local recurrence after cryosurgery is suspected. By providing chemical mapping of the prostate in contiguous voxels, the addition of spectroscopy to endorectal MRI increases the sensitivity for detection of local recurrence.

Genital presentation of filarial disease is not uncommon in endemic areas of the world. Acute, febrile illness involving the epididymis and spermatic cord (funiculoepididymitis) is one of many such presentations. With an internationally mobile society, physicians today, even in nonendemic areas, may encounter patients with filarial infestations. We report the first case of presumptive diagnosis of this disease using scrotal ultrasound.
