CT Findings

CT manifestations of cellulose granulomatosis consist of diffuse centrilobular small nodules and a tree-in-bud pattern [11] (Fig. 9.2).

CT–Pathology Comparisons

Tree-in-bud pattern seen on HRCT in patients with cellulose granulomatosis represents intra-arteriolar accumulation of microcrystalline cellulose with associated adjacent granulomatous reaction (Fig. 9.2).

Patient Prognosis

There are no established treatments for talc granulomatosis. Patients must stop the intravenous drug use. Success with steroids has been reported [12], but most believe that there is no benefit from corticosteroid therapy. Lung transplantation is considered a last option for patients with end-stage disease.
