Atypical Measles:

Clinical:

Occurs due to previous inadequate immunization with killed Rubeola virus with subsequent exposure to the measles virus. The disorder represents a Type III immune complex hypersensitivity reaction. Patients present with fever, HA, a maculopapular rash (on wrists and ankles), and arthralgias.

X-ray:

Initially the CXR reveals patchy, bilateral airspace opacifications. The parenchymal infiltrates resolve into nodular parenchymal opacifications (granulomas) which may calcify and can persist for up to 2 years. Effusions and adenopathy (hilar adenopathy in 100%) are common.
