Objective:
To analyse sonographical features of epididymis tuberculosis with caseous necrosis and improve the accuracy of ultrasonic diagnosis.
Methods:
Ultrasonic features of 12 cases with epididymis tuberculosis with caseous necrosis, confirmed by surgical pathology, was retrospectively analysed: size, location, echogenicity, degree of blood flow in the lesion.
Results:
In all 12 patients, the number of purified protein derivative test (PPD) presenting the positive reached to 67%, while cases with the pulmonary tuberculosis was 42%. The epididymal tuberculosis with caseous necrosis could present images of the whole or focal epididymal enlargement and abnormal shape. The lesions internal echoes were irregular, inhomogeneous increased isoechoic echogenicity or hypoechoic, including bad-defined, irregular, homogeneous hypoechoic or anechoic. In lesional location, 4 out of 12 patients (33%) possessed richly color blood flow in Color Doppler Power Imaging(CDPI). The testicular enlargement with increased internal echoes and the testicular hydroceles were partly (58%, 7/12) observed by ultrasound. There was no varicocele, scrotal wall thickening and inguinal lymph node enlargement.
Conclusion:
The High Frequency Color Doppler images is helpful for the diagnosis and differential diagnosis of epididymis tuberculosis with caseous necrosis.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
