Abstract
Atypical adenomatous hyperplasia (AAH) and bronchioloalveolar carcinoma (BAC) often occur around adenocarcinomas, showing ground-glass opacity (GGO) on high resolution CT (HRCT) scans. Here, we report three cases of multiple GGOs. Each case showed different numbers, appearances, and locations of GGO, making it difficult to establish a standard therapy. When we deal with multiple GGOs, we must formulate a suitable therapeutic strategy for each case including the type of operation. As for the residual GGOs after an operation, we must observe carefully the size, appearance, and density of GGOs on HRCT scans, and, if we recognize any change, we must consider further treatment including re-operation, radiotherapy, and chemotherapy.
