Rubella
Etiology: Togavirus is a neurotropic virus which replicates in placenta causing meningoencephalitis and vasculitis which leads to ischemia and microcephaly
Imaging Radiograph Musculoskeletal: — Metaphyseal fraying and longitudinal alternating radiolucent and radiodense stripes gives celery stalking appearance
Imaging Neurological: — Early infection: Near total brain destruction, microcephaly — Later infection: Ventriculomegaly, myelination abnormality, patchy frontal periventricular signal abnormalities (similar to cytomegalovirus), basal ganglia calcification, cystic changes
AP radiograph of the lower extremities shows fraying of the bilateral femoral metaphyses which have alternating radiolucent and radiodense stripes (celery stalking).AP radiograph of the knee shows shows fraying of the femoral metaphysis which has alternating radiolucent and radiodense stripes (celery stalking).AP radiograph of the knee shows shows fraying of the femoral metaphysis which has alternating radiolucent and radiodense stripes (celery stalking).
