The data of patients with reversible cerebral vasoconstriction syndrome (RCVS) who were examined and treated in 2013–2020 are presented. 136 patients were examined (37.3 ± 11.4 years) – 107 (78.7 %) women, 29 (21.3 %) men. Detailed neurological examination, magnetic resonance imaging of the brain, magnetic resonance angiography and magnetic resonance venography were performed. Results. Primary RCVS was detected in 29 (21.3%), secondary RCVS – in 69 patients (50.7%), and a combination of primary and secondary RCVS factors – in 38 (28.0%) patients. In 95 (69.8%) patients (80 women, 15 men; p < 0.05) signs of cerebral artery angiodysplasia were identified. Hypoplasia of venous sinuses (transverse and/or sigmoid) was found in 34 patients (29 women and 5 men). Conclusions. RCVS is developed in women more often than men, but there was no significant difference in risk factors between men and women. Predisposing factors of both primary and secondary RCVS can be revealed simultaneously. Women were more likely to have variants of brachiocephalic artery development. Clarification of angiodysplasia variant influence to the development and severity of RCVS requires further study.

Volumetric Measurements

The objective of this study is to investigate the dimensional and volumetric measurements in the thyroarytenoid (TA) muscle in men and women using magnetic resonance imaging (MRI). The hypothesis is that there is a gender-related difference in these measurements. A retrospective chart review of 76 patients who underwent MRI of the neck at the American University of Beirut Medical Center was conducted. The dimension and volume of the right and left TA muscle were measured on axial and coronal planes short tau inversion recovery images. Male and female groups were compared with respect to demographic data and MRI findings using parametric and nonparametric tests. The mean length of the thyro-arytenoid muscle in males was larger than that in females on the right (males 2.44 [0.29] cm vs females 1.70 [0.22] cm) and on the left (males 2.50 [0.28] cm vs females 1.72 [0.24] cm) reaching statistical significance ( P < .001). The mean width of the thyro-arytenoid muscle in males was larger than that in females on the right (males 0.68 [0.13] cm vs females 0.59 [0.11] cm) and on the left (males 0.68 [0.12] cm vs females 0.57 [0.12] cm) reaching statistical significance ( P < .001). The mean height of the thyro-arytenoid muscle in males was larger than that in females on the right (males 1.05 [0.21] cm vs females 0.95 [0.12] cm) and on the left (males 1.05 [0.21] cm vs females 0.95 [0.12] cm) reaching statistical significance ( P < .01 on the right and P < .05 on the left). The volume of the thyroarytenoid muscle in males was larger than that in females on the right (males 0.86 [0.25] mL vs females 0.48 [0.15] mL) and on the left (males 0.89 [0.27] mL vs females 0.48 [0.17] mL) reaching statistical significance ( P < .001). The results of this investigation clearly indicate a significant difference in these measurements between men and women.

Reversible cerebral vasoconstriction syndrome (RCVS) is a syndrome characterized by severe headache with segmental vasoconstriction of the cerebral arteries that resolves within 12 weeks. A 16-year-old girl with refractory cytopenia of childhood, who was receiving the immunosuppressant cyclosporine, developed severe headache and was diagnosed with RCVS using magnetic resonance imaging, including magnetic resonance angiography (MRA). MRA is a non-invasive and very effective technique for diagnosing RCVS. MRA should be performed at the onset of severe headache during immunosuppressant administration for children with hematological disorders and may prevent sequelae such as posterior reversible encephalopathy syndrome or ischemic attack.

Headache Onset

Background The temporal and anatomical features of vasoconstriction in patients with reversible cerebral vasoconstriction syndrome within hours after symptom onset, in the hyperacute phase, are unclear. Case result Herein we report the cases of two patients with acute severe headache who were diagnosed with reversible cerebral vasoconstriction syndrome. Magnetic resonance imaging within hours after symptom onset revealed multiple areas of isolated cortical vasogenic edema and hyperintense vessel signs of the distal cerebral arteries. Follow-up imaging performed four days later in both cases showed diffuse segmental arterial vasoconstriction in the proximal regions of the cerebral arteries. Both patients received antivasoconstrictive therapy shortly after admission, and neither had neurological sequelae at discharge. The magnetic resonance imaging findings improved gradually within three months after symptom onset. Conclusion Isolated cortical vasogenic edema and hyperintense vessel signs, when observed within hours from sudden severe headache onset, may be useful early markers of reversible cerebral vasoconstriction syndrome.

Sixty-two patients (40 women and 22 men) with multiple sclerosis (MS) were examined with 1.5 tesla magnetic resonance imaging (MRI) of the brain. Information on sexual and sphincteric disturbances has been collected, and data on disability, independence, cognitive performances and psychological functioning have been assessed. C alculations of T1- and T2-lesion load (LL) of total brain, frontal lobes and pons have been performed using a reproducible semiautomated technique. Whole brain, frontal and pontine atrophies were estimated using a normalized measure, the brain parenchymal fraction (BPF), obtained with a computerized interactive program. When comparing patients with and without sexual dysfunction (SD), there were no differences in total brain, frontal and pontine T1- and T2-LL, as well as in measures of whole brain and frontal atrophy. The only significant difference was in the pontine BPF (P-0.026). In linear multiple regression analysis, SD was associated with depression (R-0.56, P-0.001) and, after adjusting for depression and anxiety, with bladder dysfunction (R-0.43, P-0.003) and pontine BPF (R-0.56, P-0.001). No association between SD and any of the measures of T1- and T2-LL was found. The findings showed a relationship between SD and pontine atrophy, confirmed the correlation of SD with bladder dysfunction and highlighted the role of psychological factors in determining SD.
