CHRONIC SUBDURAL HAEMATOMA AND AUTOSOMAL POLYCYSTIC KIDNEY DISEASE: REPORT OF TWO NEW CASES

SUMMARY:  Chronic subdural haematoma (SDH) was recently described in some patients who were suffering from autosomic dominant polycystic kidney disease (ADPKD). It results in various neurological symptoms mimicking those related to intracranial aneurysms, which are relatively frequent in such patients. The authors report two cases of chronic SDH observed in two patients known to have advanced renal failure attributed to ADPKD. Medical imaging failed to reveal features of associated intracranial abnormalities such as aneurysms or arachnoid cysts. Surgical drainage resulted in a good recovery without relapse during a long period of follow up that exceeded 10 years in the first case.
