The authors measured the average diameter of bilateral superior ophthalmic veins (SOV) in 13 patients with spontaneous intracranial hypotension (SIH) on contrast-enhanced, coronal, T1-weighted MRI. Compared with sex- and age-matched neurology inpatients with normal CSF pressure, the SIH group had a smaller SOV diameter (0.90 vs 1.85 mm, p < 0.001), which(More)
We consecutively recruited 21 patients (all women, mean 54 +/- 8 years) with bath-related thunderclap headache (BRTH). Thirteen of them were in menopause, two had just ceased hormonal therapy, and one was at 3 months postpartum. Bathing was the initial trigger for thunderclap headaches in nine patients (43%). Many patients (n = 15, 71%) had other(More)
We describe a case of decerebrate rigidity, with preservation of consciousness, caused by a discrete pontine tegmentum lesion identified on MR imaging. Lesions within a certain brain stem region are responsible for decerebrate rigidity in animal studies, but there has been a lack of MR imaging evidence in humans. This report also implies that a discrete(More)
