Total intracranial shunt migration

Rare complication of ventriculoperitoneal shunt. Early onset of distal catheter migration into scrotum in an adult male: Case report and literature review

“…One of the rare sites of distal catheter migration is the scrotum. 32,46 Other reported sites of migration include the ventricle, 34 scalp/subgaleal space, 10 neck, 11 mouth, 30 breast, 31 breast implant, 52 thoracic cavity, 17 pulmonary artery, 35 intracardiac, 60 lungs/pleural space/trans-diaphragmatic, 7,25,50 anterior chest wall, 6 intra-abdominal wall, 39 abdominal subcutaneous fat tissue, 33 umbilicus, 23 stomach, 3 large intestine, 15 liver, 57 gall bladder, 41 bladder/urethra, 9 inguinal sac, 62 buttocks, 48 canal of Nuck, which is the female counterpart of the spermatic cord, 63 vulva/vagina, 55 rectum/anus, 54 and knee. 36 Although cases of scrotal migration of distal catheter have been reported in pediatric patients, cases in adult patients are rare due to obliterated processus vaginalis.…”

Complete intracranial migration of a ventriculoperitoneal shunt: Rare complication of a common procedure

“…[4] Excessive neck movements producing a windlass effect coupled with a large potential subgaleal space created for chamber positioning, dilated ventricles with negative suctioning pressure, or a positive intra-abdominal pressure may be responsible for the migration. [8] [6] The "Chabbra" shunt, having a cylindrical chamber can easily pass into the cranium.…”

The nerve of legal entrapment

“…Chordomas are usually slow-growing tumors, with a tendency to invade locally [ 1 – 7 ]. This cancer can arise at any point along the spinal cord with the sacrum being the most commonly affected (50–60%) followed by the base of the skull where the annual incidence is estimated to be 0.089 per 100,000 and whose overall median survival time is 9.2 years after appropriate therapy [ 1 , 2 , 5 – 7 , 8 ]. Given the subtle presentation, diagnosis can be challenging, and management of this exceedingly rare disease is still evolving.…”
