sodium-pertechnetate-tc-99m and Testicular-Diseases

Tc-99m pertechnetate radionuclide scrotal scanning was performed on nine hospitalized boys with anaphylactoid purpura and acute scrotal tenderness. Scrotal involvement in anaphylactoid purpura is generally a part of the basic pathological process (i.e., vasculitis). Sometimes testicular torsion could not be excluded by physical examination. Tc-99m radionuclide scan was proven to be a useful tool, enabling distinction between the two processes. In all the patients the scan showed increased flow to the scrotum, compatible with inflammation of the scrotal wall and normal testicular perfusion, ruling out testicular torsion. All the boys were treated conservatively, with rapid resolution of the scrotal symptoms.

Testicular trauma is not uncommon. Apart from accidental trauma it may deliberately be inflicted during fight by striking blows in the scrotal area. The most common posttraumatic complications are hematoma, hydrocele and hematocele, orchiepididymitis and occasionally malignant degeneration of the injured testis. Unless diagnosed and treated in time, these complications lead to hypoplasia and atrophy of the testes, the far-reaching result being sterility. Fifteen patients 17 to 40 years of age, undergone testicular trauma, comprise the study group. In 8 patients no changes were recorded. In the other group of 7 patients 1 had hematoma, 4 hydrocele, 1 orchiepididymitis and 1 (six months after the trauma)--tumor of the testis--teratocarcinoma. It is concluded that gamma-camera scintigraphy of the testis is a quick and exact method, which furnishes ample information on the complications following testicular trauma thus tracing a correct approach to treatment.

Twenty-five patients suffering from acute painful testicular processes were subjected to scintigraphy. Testicular torsion in the early and delayed phases were diagnosed with 100% accuracy, but one out of 7 cases of epididymitis was wrongly recognized as negative. Interoperative diagnosis in two cases of hydatid torsion proved the foregoing scintigraphic finding to have been wrong. Nevertheless, scintigraphy was found to be reliable in testicular torsion diagnosis.

A rare case of epidermoid cyst of the testis, represented scintigraphically by an area of avascularity in the affected testicle, is described. The differential diagnosis from epididymitis and torsion of testis, and the diagnostic value fo the scintigraphic method to rule out malignant (vascular) testicular tumors, is emphasized.

Technetium-99m sodium pertechnetate scintigraphy is an established method for evaluating organ perfusion and can be applied to the investigation of suspected testicular ischaemia due to acute torsion. One hundred and six consecutive scrotal investigations have been analysed qualitatively and quantitatively using a computer-based comparison of the perfusion slopes over each testis. Decreased vascularity on the symptomatic side only occurs in torsion and quantitative analysis is needed to detect it reliably. Increased vascularity on the symptomatic side can usually be detected qualitatively and occurs in orchitis, tumours, trauma and resolved torsion. Distinction between the causes of increased vascularity is aided by the clinical data. A halo of increased activity surrounding a relatively cold centre was seen in chronic torsion, some tumours and hydrocoeles. The test is both sensitive and specific for acute torsion but its usefulness is limited if it is not available at all hours. The test is useful, also, in confirming a diagnosis that does not require emergency operation and in identifying chronic torsion which is an indication for contralateral orchidopexy.
