In Cauda Venenum

Evaluation of frozen thawed cauda epididymal sperms and in vitro fertilizing potential of bovine sperm collected from the cauda epididymal

In the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. The cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. Sperm fertility potential was tested...

Cauda Equina syndrome

A 26-year-old male with a history of a work-related back injury presented to the emergency department complaining of several weeks of low back pain radiating down his left leg. For the past day, he noticed numbness to his perineal area and feet bilaterally, and difficulty urinating. He denied recent trauma, leg weakness, or fevers.

Cauda Equina Disorders

ANATOMY The spinal cord tapers to its end, the conus medullaris, usually at the lower edge of the first lumbar vertebra. The continuation of the spinal cord is a strand of connective tissue, the filum terminale. The ventral and dorsal lumbar and sacral nerve roots that arise from the conus medullaris form a bundle, the cauda equina (Figure 1). These lumbar and sacral spinal nerve roots separate...

Imaging the cauda equina

Mobile cauda equina schwannomas

Although very rare, cases of cauda equina tumours migrating several levels have been known to occur. We report two cases of cauda equina schwannomas which migrated from its primary site, one caudally and the other one rostrally as confirmed by magnetic resonance imaging perioperatively. The f irst patient was a 27-year-old man and the second a 41year-old man; both presented with back pain. This...
