Although infection with the Zika virus was first recognized in 1942, it received
little attention until 2007, when a true pandemic spread throughout Africa,
Asia, and the Americas. Since then, numerous forms of central nervous system
involvement have been described, mainly malformations related to congenital
infection. Although the neuroimaging findings in congenital Zika syndrome are
not pathognomonic, many are quite suggestive of the diagnosis, and radiologists
should be prepared to interpret such findings accordingly. The objective of this
article is to review the computed tomography and magnetic resonance imaging
findings in congenital Zika syndrome.
Sporotrichosis in children is rare, and its osteoarticular form is very unusual. Disseminated forms are described mostly in immunocompromised patients. We report a case of a 5-year-old immunocompetent boy with multiple suppurated cutaneous lesions that progressed to polyarthritis of the hands and feet. Radiographic imaging demonstrated multifocal lytic lesions. Sporotrichosis was diagnosed through biopsy and culture. This article describes the radiographic appearance of a rare manifestation of this disease. In areas of high prevalence, the diagnosis of sporotrichosis should be taken into account, even in immunocompetent patients, when dactylitis with lytic lesions is present.
Parry-Romberg syndrome is a rare disease characterized by progressive hemifacial
atrophy associated with other systemic changes, including neurological symptoms.
Currently, there are few studies exploring the utilization of advanced magnetic
resonance sequences in the investigation of this disease. The authors report the
case of a 45-year-old patient and describe the findings at structural magnetic
resonance imaging and at advanced sequences, correlating them with
pathophysiological data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
