— Two patients with herpes zoster ophthalmicus (HZO) who experienced a delayed contralateral hemiparesis, the so‐called crossed zoster syndrome, are described. Particular emphasis is paid to the cerebral blood flow (CBF) findings studied with the Xenon‐133 inhalation technique using single photon emission computed tomography (SPECT). In a 40‐year‐old female with right‐sided hemiparesis, angiography showed multiple segmental narrowings of the intracerebral arteries. Cerebral computer tomography (CT) scans were normal. The CBF studied 11 months after the HZO showed a generalized reduction of flow which, however, was more pronounced in the left hemisphere. On re‐examination 8 months later both the mean hemispheric flow and regional CBF (rCBF) had increased to normal values. In a 66‐year‐old male with dysphasia and right‐sided hemiparesis, cerebral CT scans demonstrated two small deep left‐sided infarcts. CBF examination showed a generalized reduction of flow in the left hemisphere. The flow was slightly increased on re‐examination 12 months later. These findings suggest that the Xenon‐133 inhalation method represents a useful way to demonstrate the CBF pattern in this group of patients.
