[Aspergillus mycoses of the paranasal sinuses. Detection and analysis of roentgen opaque structures in fungal concretions].

Out of 59 patients with aspergillosis of the paranasal sinuses 25 showed almost metal-dense X-ray-shadows in Highmore's sinus, resembling foreign bodies at first. It can be demonstrated, that these areas are equivalent to local enrichment of calcium phosphate mainly in the center of the fungal masses in the sinuses. Technique and methods of investigation and analysis are described. X-ray findings like these should be looked upon as a sign reading: "aspergillosis of the paranasal sinuses ahead."
