Acute abscess of the mediastinum is exceedingly rare in infancy and in childhood. Müller1 quoted Hare, who reported a series of sixty-six cases gathered from the literature, in which only six patients were in the first decade of life and nine patients in the second decade. Cook2 reported four cases, in which the patients were 8 months, 8 years, 11 years, and 16 years of age, respectively. Achenbach3 reported a case in an infant, aged 3 weeks, following sepsis from thrombo-enteritis of the left umbilical artery and grip. Von Dehn4 reported a case of bilateral empyema with abscess of mediastinum in a child, aged 3 years. I have not found one case of pure mediastinal abscess in the records of the Milwaukee Children's Hospital, although the records of two cases showed acute generalized mediastinitis with death, following tracheotomy and acute retropharyngeal abscess.
