BACKGROUND AND PURPOSE: Iatrogenic cerebral amyloid angiopathy (iCAA) is a specific type of cerebral amyloid angiopathy which is becoming increasingly diagnosed. It has been hypothesized that iCAA might arise as a late consequence of past neurosurgical interventions involving dural patch grafts. Positron emission tomography (PET) scans with amyloid tracers and the assay of beta-amyloid levels in cerebrospinal fluid (CSF) are auxiliary criteria, however, definite diagnosis remains histopathologically determined.
METHODS: Case report.
RESULTS: We present a 48-year-old patient who suffered multiple lobar cerebral haemorrhages from the age of 47. The patient had undergone surgery for remolval of hemangioblastoma with lyophilized dural graft at the age of 11, in 1987. Brain MRI, amiloid PET and CSF analysis led to a diagnosis of probable iCAA.
CONCLUSION: It is necessary to increase the awareness of iCAA, in order to avoid overlooking the potential causal involvement of surgical procedures which took place far back in time. Moreover, the diagnostic relevance of amyloid PET and beta-amyloid levels in CSF must be emphasised.
