Cervicofacial vascular anomalies can result in morbidity, pain, and cosmetic concerns in affected individuals. Each anomaly has its own unique natural history, treatment, and associations with underlying genetic syndromes. For optimal patient care, it is important for the neuroradiologist to accurately recognize and characterize these entities to ensure appropriate treatment and management. In this review, we discuss the general characteristics, classifications, and imaging features associated with the most common vascular anomalies such as hemangiomas, arteriovenous malformations and fistulas, capillary malformations, venous malformations, and lymphatic malformations in the context of associated syndromes. Additionally, we discuss novel imaging techniques that aid in identifying these vascular anomalies.

ObjectiveTo determine the incidence of psoriatic arthritis (PsA) in a US population and describe trends in incidence and mortality over 5 decades.MethodsThe previously identified population‐based cohort that included Olmsted County, Minnesota residents ≥18 years of age who fulfilled PsA criteria during 1970–1999 was extended to include patients with incident PsA during 2000–2017. Age‐ and sex‐specific incidence rates and point prevalence, adjusted to the 2010 US White population, were reported.ResultsThere were 164 incident cases of PsA in 2000–2017 (mean ± SD age 46.4 ± 12.0 years; 47% female). The overall age‐ and sex‐adjusted annual incidence of PsA per 100,000 population was 8.5 (95% confidence interval [95% CI] 7.2–9.8) and was higher in men (9.3 [95% CI 7.4–11.3]) than women (7.7 [95% CI 5.9–9.4]) in 2000–2017. Overall incidence was highest in the 40–59 years age group. The incidence rate was relatively stable during 2000–2017, with no evidence of an overall increase or an increase in men only (but a modest increase of 3% per year in women), compared to 1970–1999 when a 4%‐per‐year increase in incidence was observed. Point prevalence was 181.8 per 100,000 population (95% CI 156.5–207.1) in 2015. The percentage of women among those with PsA increased from 39% in 1970–1999 and 41% in 2000–2009 to 54% in 2010–2017 (P = 0.08). Overall survival in PsA did not differ from the general population (standardized mortality ratio 0.85 [95% CI 0.61–1.15]).ConclusionThe incidence of PsA in this predominantly White US population was stable in 2000–2017, in contrast to previous years. However, an increasing proportion of women with PsA was found in this study.

AbstractBackground/ObjectivesTo determine the role of sex in port‐wine stain (PWS) distribution and describe the epidemiologic and anatomic differences between syndrome‐associated and non‐syndrome‐associated PWS using modern criteria.MethodsA retrospective review of PWS patients aged 18 years and younger from 1995 to 2018 seen in the Department of Dermatology at an academic tertiary referral center. Cases were reviewed for sex, anatomic location, and presence of associated syndrome. 4,527 records were reviewed on the basis of ICD billing codes for congenital vascular malformations, with 516 meeting inclusion criteria.Results516 patients were included in the analysis: 234 (45.4%) men and 282 (54.6%) women. A female preponderance of Sturge‐Weber syndrome (18 of 23, 78%, P = .03) and a trend toward more female‐isolated PWS (149 of 269, 55%, P = .72) were found. No lateral predominance observed for isolated PWS was found: 112(41.6%) limited left‐side lesions and 113(42%) limited right‐side lesions (P = .41). A trend toward Klippel‐Trenaunay syndrome (KTS)‐associated PWS occurring more commonly isolated to the left side (76 (45.5%) vs 59 (35.12%) P = .29) was found. Nine percent of SWS patients had a PWS on the body. Five percent of KTS patients had a facial PWS. The lower limb was the most common location overall of body PWS with 33.8% of isolated PWS and 81.5% of KTS patients having a lower limb lesion.ConclusionsFemale children were more likely to be diagnosed with SWS, and a trend toward more isolated PWS in women was found. No lateral predominance of isolated PWS was found, but KTS‐associated PWS was more common on the left. A considerable proportion of lesions do not appear in anatomic locations traditionally considered typical in the setting of associated syndromes, which underscores the importance of conducting a complete physical examination and adhering to diagnostic criteria for those syndromes.
