Images from a 28-year-old woman (case 6) with puerperium-related reversible cerebral vasoconstriction syndrome. The patient was admitted to the hospital 1 day after onset. A, The initial MRA obtained 1 day after the onset of thunderclap headache shows vasoconstrictions in the bilateral P2–3 portions of the posterior cerebral arteries (black arrows). B, MRA obtained at the time of TCH remission (12 days after onset) shows centripetal propagation of vasoconstriction in the bilateral P2 (black arrows) and P1 (white arrows) portions of the posterior cerebral arteries and bilateral A1 portions of the anterior cerebral arteries (black arrowheads).

Images from a 60-year-old woman (case 8) with bath-related reversible cerebral vasoconstriction syndrome. The patient was admitted to the hospital 2 days after onset. A and C, Initial MRA obtained 2 days after onset of thunderclap headache shows vasoconstrictions in the bilateral distal MCAs (dotted circles) and bilateral P2–3 portions of the posterior cerebral arteries (C, circle). B and D, MRA obtained at the time of TCH remission (20 days after onset of TCH) shows centripetal propagation of vasoconstriction in the bilateral A1 portions (B, black arrowheads) and A2 portions (B, black arrow) of the anterior cerebral artery, bilateral internal cerebral arteries (D, black arrowheads), the left P1 portion of the posterior cerebral artery (D, black arrows), and the basilar artery (B, white arrowheads). Vasoconstriction of the bilateral P2–3 portions was improved, but some findings remained on MRA at the time of TCH remission.
