Mycetoma:

Clinical:

Mycetomas are masses of fungal hyphae. They result from the saprophytic growth of fungus within a preformed cavity- frequently secondary to tuberculosus infection or sarcoidosis. Over 90% of mycetomas are due to Aspergillus species- most commonly A. fumigatus. Hemoptysis develops in 50-95% of patients with mycetomas. Invasive aspergillosis is another potential complication which occurs in about 20% of patients.

X-ray:

A mycetoma presents as a soft tissue density mass on chest radiograph, but on careful inspection a crescent-shaped lucency of air can be identified about the non-dependent portion of the mass. The walls of the cavity are usually thin and smooth. The mass will move within the cavity with changes in patient position.
