Takayasu's arteritis (TA) is a chronic inflammatory vascular disease that mainly affects large vessels. Central nervous system involvement occurs in about 20% of cases with rare involvement of intracranial vessel, and its typical manifestation is cerebral ischemia or stroke. Reversible cerebral vasoconstriction syndrome (RCVS) is a group of disorders with prolonged, but reversible vasoconstriction of the cerebral arteries with acute-onset, severe, recurrent headaches with or without neurologic signs or symptoms. We report a case of TA in a 17-year old girl who presented with secondary RCVS. She complained of thunderclap headache, seizure and acute stroke. 3-dimensional computed tomography scan and magnetic resonance angiography of head revealed irregular thickening of aortic wall and its main branches with multifocal narrowing of intracranial basilar artery, which improved after oral nimodipine intake. This case highlights RCVS as an unusual manifestation of TA and demonstrates the diagnosis, treatment and response to therapy of RCVS in TA, which resolved after treatment with calcium channel blocker.

Carbon monoxide is a nonirritant, odorless, colorless gas. Its effects are prominent in organs most sensitive to oxygen deprivation, such as the heart, brain, and kidney. Although less frequently, an association between thromboembolic events and carbon monoxide poisoning has been shown in the literatures. In this case, we report a case of atrial thrombus associated with carbon monoxide poisoning.
