Scrotal ultrasonography: a clinical evaluation

Abstract

Two hundred and thirty patients had scrotal ultrasonography over an 18-month period. We report the ultrasound findings, correlation with the clinical diagnosis and, where possible, with the pathological diagnosis. The results show the value of scrotal ultrasonography in clinical practice. Of particular interest is the ultrasonic examination of the clinically normal or impalpable testis and the correct ultrasound diagnosis of testicular tumour in five cases (2% of all cases, 28% of tumours detected) thought clinically to be benign. A brief review of abnormal appearances is included.

Evaluation of Scrotal Lesions by Gray Scale Ultrasonography and Colour Doppler

“…In the present study, all cases of testicular tumours were encountered and diagnosed in all cases with nearly same accuracy reported by Fowler et al [6] The sonographic characteristic of testicular tumours was the heterogeneous appearance of the testes. Tumour lesions appeared less echogenic than normal testes in 83% of cases, also reported by Arger et al [7] The seminoma was hypoechoic, homogeneous and had sharply circumscribed margins, while Nonseminomatous Germ Cell Tumours (NSGCT) were characterized by heterogeneous echotexture, irregular margins and cystic spaces.…”

Viralization Due to Leydig Cell Tumor Diagnosis by Magnetic Resonance Imaging

“…Ultrasound sensitivity for focal neoplasms has been very high. 4 Recently, development and application of MRI to testicular scanning has been reported. Preliminary evidence suggests that MRI may be even more sensitive for detecting focal testicular abnormalities than ultrasound, though not necessarily more histologically specific.8 In particular, a recent report described a 5-year-old boy whose occult Leydig cell tumor was detected by MRI but not by ultrasound.g This patient was studied with a 0.35T unit; whereas our patient was scanned with a high field strength MRI scanner that yielded images with superior resolution.…”

Ultrasonography versus clinical examination in evaluation of testicular tumors

“…False-negative ultrasonographic diagnoses of a testis tumor have seldom been reported in the literature. [15][16][17][18] In m ost cases, the ultrasonographic features of the tumor did not differ (enough) from the normal surrounding testis parenchyma. In our study, there were 7 false-negative clinical diagnoses, but no false-negative ultrasonographic diagnoses.…”
