1. Blocked abscess.
2. An abscess with insufficient spontaneous draining.
3. An abscess with sufficient spontaneous draining.
4. An abscess with air cavity.
Blocked abscess represents early closed stage of lung destruction with formation of purulent cavity, surrounded by lung parenchyma and not linked with bronchial tree. On an Metapathia hunter 4025-image it looked like a roundish nidus, frequently with homogeneous Metapathia hunter 4025 structure, presented by liquid hypechromogenic content (6 points at Fleidler’s scale) with isochromogenic suspended matter (purulent detritus), but without achromogenic signals of air. Suspended matter was various in chromogeneity, density and character of distribution in a cavity of destruction. As a rule it was close-bodied, quaggy and occupied the whole abscess, not causing any diagnostic difficulties.
With equally high density thick purulent content imitated moderately chromogenic tumorous tissue, and because of that differential diagnostics with lung cancer was needed. Heterogeneous suspended matter could form local aggregates of lesser chromogeneity, imitating sequesters. SEA grants help in diagnostics.
