Dorsal thalamic haemorrhage complicating polyarteritis nodosa: a clinico-pathologic case report

Intracerebral haemorrhage is a rare complication of polyarteritis nodosa (PAN). We present the clinico-pathologic findings of a 62 year-old patient with systemic involvement by PAN, who developed temporary decrease of consciousness and a mild left hemisyndrome due to a small right dorsal thalamic haemorrhage. No clear cause for the haemorrhage was found on postmortem examination.
