  2. Pelvic compression syndrome - Wikipedia

    en.wikipedia.org/wiki/Pelvic_compression_syndrome

    While one may expect the female to have an equal prevalence of pelvic compression syndrome due to the identical embryological origin of the valveless pampiniform plexus, this condition is thought to be underdiagnosed due to the broad differential of the pain pattern: unilateral or bilateral pain, dull to sharp, constant to intermittent pain worsening with any increase in abdominal pressure.

  3. Pampiniform plexus - Wikipedia

    en.wikipedia.org/wiki/Pampiniform_plexus

    The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.

  4. Lumbar veins - Wikipedia

    en.wikipedia.org/wiki/Lumbar_veins

    The 3rd and 4th lumbar veins drain into the inferior vena cava. [3]The fate of the two superior lumbar veins is far more variable, and may drain into either the inferior vena cava, ascending lumbar vein, azygos vein, or (on the left side) the left renal vein; the 1st lumbar vein often passes inferiorly to join the 2nd lumbar vein, but may less commonly drain into the ascending lumbar vein, or ...

  5. Varicocele - Wikipedia

    en.wikipedia.org/wiki/Varicocele

    A varicocele is, in a man, an abnormal enlargement of the pampiniform venous plexus in the scrotum; in a woman, it is an abnormal painful swelling to the embryologically identical pampiniform venous plexus; it is more commonly called pelvic compression syndrome. In the male varicocele, this plexus of veins drains blood from the testicles back ...

  6. Parsonage–Turner syndrome - Wikipedia

    en.wikipedia.org/wiki/Parsonage–Turner_syndrome

    This syndrome can begin with severe shoulder or arm pain followed by weakness and numbness. [5] Those with Parsonage–Turner experience acute, sudden-onset pain radiating from the shoulder to the upper arm. Affected muscles become weak and atrophied, and in advanced cases, paralyzed. Occasionally, there will be no pain and just paralysis, and ...

  7. Magnetic resonance neurography - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_neurography

    The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...

  8. Cerebrospinal venous system - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_Venous_System

    Beginning in 1937 Batson began a series of injection experiments investigating the anatomy and physiology of the cerebrospinal venous system. [2] His carefully documented results demonstrated the continuity of the venous systems of the brain and the spine, as injections of contrast dyes into venous systems feeding into the spinal venous plexus led to the appearance of contrast material in the ...
