Anamnesis
Identification: Male patient, 72 years old, with a history of hypertension and diabetes, and no prior history of migraine.
Clinical history: The patient reports recurrent episodes of positive visual phenomena, described as "bright flashes" and "scintillating lines," lasting about 15 minutes, followed by transient numbness in the right hand and arm. Symptoms resolve spontaneously without permanent deficits. There is no associated headache, or only a mild headache is present.
Imaging findings: Brain magnetic resonance imaging (MRI) with blood-sensitive sequences (SWI and GRE) shows multiple lobar microbleeds and superficial cortical siderosis, findings suggestive of cerebral amyloid angiopathy (CAA).
Report this case — e.g. suspected re-identification risk.
