Vortex

    A child 15 years-old with no complaints at echo-screening, previously diagnosed left spermatocele.

    In the current US above the upper pole of the left testicle visualized a vortex ( whirlpool sign) - torsion of the spermatic cord more than 360 deg., in the testicle is visualized both spectrums of blood flow (arterial, venous).

    "A median of 540 degrees of torsion (range 180 to 1,080) was noted in the 70 orchiectomy cases (38%) and a median of 360 degrees (range 180 to 1,080) was noted in the 116 salvaged testes (62%)."

    "2-3 small lymph nodes with central hilar echoes seen in right inguinal region. Larger one measures 15mm × 9mm. What does it mean sir ?"

    Duplicate my answer here:

    "Lymph nodes are part of the human body's immune system. They can enlarge for various reasons, including infectious, allergic, lymphoproliferative and other diseases. Their normal size, according to different authors, differs in different areas of the human body. In the classical understanding of the normal condition of adults, the lymph node is normal up to a maximum of 10 mm, however, these views are currently being revised upward by the medical community, including the maximum normal size for inguinal lymph nodes up to 15 mm in transverse size at https:/ /radiopaedia.org/articles/inguinal-lymph-nodes

    In your message describes lymph nodes that are normal in structure, the size of which, according to modern views, can also correspond to the normal condition of adults.

    However, you should consult an offline GP for a personal consultation."
