  • Title: Intracerebral hemorrhage associated with Sneddon's syndrome: is ischemia-related angiogenesis the cause? Case report and review of the literature.

    Abstract:
    Sneddon's syndrome is characterized by livedo reticularis and multiple ischemic infarcts often associated with antiphospholipid antibodies. Intracerebral hemorrhage (ICH) is unusual in Sneddon's syndrome and has not been reported as the presenting complaint. We report a 38-year-old woman with a history of two miscarriages, Raynaud's phenomenon and livedo reticularis who presented acutely with ICH. Angiography showed prominent leptomeningeal and transdural anastomoses (pseudoangiomatosis). Anticardiolipin antibodies were positive. A right frontal brain biopsy failed to reveal vasculitis and a skin biopsy was nonspecific. MRI showed residual intracerebral hemorrhage (ICH), diffuse atrophy, multiple small white matter infarcts and leptomeningeal enhancement. This is the first report of Sneddon's syndrome presenting with an ICH. It shares features with the Divry-van Bogaert syndrome. We discuss the cause of the pseudoangiomatosis pattern and its role in the genesis of the hemorrhage and suggest that cerebral angiography should be done in every patient with Sneddon's syndrome, as it could impact therapy.
