Recurring episodes of temporary hemiparesis in young adults are often regarded as ischaemic or migrainous attacks, although non-vascular pathogenesis such as multiple sclerosis should not be ruled out. Vasospasm is known to accompany migraine, but spontaneous vasospasm as a cause of temporary hemiparesis has been rarely demonstrated except in those cases induced by subarachnoid haemorrhage and those induced by mechanical manipulations.

We report a case of repeated internal carotid artery (ICA) vasospasm. Magnetic resonance angiography (MRA), colour coded duplex sonography (CCDS), and [99mTc]-hexamethylpropyleneamine oxime single photon emission computed tomography (HMPAO-SPECT) together were successful in demonstrating the ICA vasospasm and resulting cerebral ischaemia.

Case report
A 35 year old right handed man presented at our department for repeated transient one sided weakness. His parents were second cousins. His father died of stroke at the age of 46 years and his mother dies of a severe asthma attack aged 52 years. His 33 year . . . [Full text of this article]
