It is usually preceded by a viral illness, particularly influenza virus infection. Objective: To describe a cluster of BACM cases that were seen in a paediatric unit. Patients and Methods: A retrospective serie of cases that presented with a clinical picture suggestive of BACM between August and November 2012 in the paediatric emergency department of a private clinic. Results: Nine children, between 4 and 12 years, presented with a history of a recent febrile upper viral respiratory infection, followed by intense calf pain and claudication. They all recovered without complications. Laboratory results showed a marked increase in CK, with a mean of 4,066 IU/l. Three of the cases had influenza B infection and one Mycoplasma pneumonia infection. They were managed conservatively with hydration and non-steroidal anti-inflammatory drugs. Conclusions: BACM is a benign entity with a characteristic clinical presentation that can be managed most of the time in the ambulatory setting, avoiding invasive studies and unnecessary hospital admission.6spaViral myositisInfluenzaLimpChildrenArtículo
