Radiographic findings in patients with esophageal involvement by mediastinal granuloma.

Of 97 patients with mediastinal granuloma, 13 had involvement of the esophagus by extension from adjacent lymph nodes or pleura. A knowledge of the anatomic relationships of these structures is important in understanding the distribution and radiologic features of these lesions. The most common manifestation was extrinsic compression, being present in 7 (54%) of the 13 patients. Three patients (31%) had either a fistula or a sinus tract. Esophageal stricture and diverticulum formation also occurred. Mediastinal granuloma should be considered in the differential diagnosis in patients with any of these findings.
