Review Case Reports
[Intrathoracic migration of a ventriculoperitoneal shunt catheter: a case report].
The intrathoracic complications from ventriculoperitoneal shunt placement are very rare. However, they are potentially serious if not treated. ⋯ All reports recommend early catheter repositioning into the peritoneal cavity after diagnosing the migration described, to prevent worse complications. Moreover, it is important to keep in mind that intrathoracic migration can happen and it is necessary to palpate the catheter continuously during passage through subcutaneous tunnelling to prevent it.

Isolated neurosarcoidosis (INS), as a disease of low prevalence, is commonly overlooked in differential diagnosis, and its discovery on histopathological examination usually comes as a surprise. Preoperative diagnosis is difficult because the clinical picture of INS is non-specific. ⋯ Although up to 5% of all sarcoidosis patients present with neurological symptoms, those with INS are exceptionally infrequently encountered. Three cases of INS are presented here, analysing their clinical course and radiological images, in order to determine characteristic traits that might lead to a correct diagnosis.
