title: Calcification in invasive tracheal aspergillosis demonstrated on ultrasound: a new finding.
abstract: Invasion of the major airways is a rare manifestation of respiratory tract involvement by Aspergillus sp. and is seen almost exclusively in immunocompromised patients. We present calcification as a new feature of this condition and its demonstration by ultrasound in a 15-year-old boy with severe neutropenia secondary to aplastic anaemia.
