Fournier's gangrene with retroperitoneal extension in an immunocompetent patient.

A male patient in his 80s presented with the classic signs of Fournier's gangrene. At his initial debridement, an unusual florid involvement of the right cord was noted requiring a right inguinal orchidectomy in addition to extensive debridement. Although he subsequently stabilised in the intensive care unit, his inflammatory markers were noted to uptrend again requiring a relook procedure which revealed evidence of progressive necrosis in the right inguinal region.

Proton magnetic resonance spectroscopy of the central, transition and peripheral zones of the prostate: assignments and correlation with histopathology.

Proton magnetic resonance spectroscopy (MRS) is used to compare the chemistry of the transition, central and peripheral zones of the prostate. The assignments are made using two-dimensional correlated spectroscopy and the results compared with histopathology. The chemistry associated with benign prostatic hyperplasia (BPH), prostate intraepithelial neoplasia (PIN) and malignant biopsy tissues are described.

Pathologic characterization of human prostate tissue with proton MR spectroscopy.

Purpose: To assess the accuracy of magnetic resonance (MR) spectroscopy in documenting the chemical features of human prostate tissue and to ascertain if there are chemical criteria of diagnostic importance.

Materials And Methods: Seventy-seven prostate tissue specimens (peripheral zone, n = 61; transitional zone, n = 16) from 43 patients were analyzed with MR spectroscopy. Histologic features were compared with MR spectroscopic data.
