Abstract

Suture granuloma is a benign tumor defined by an inflammatory reaction and the formation of granuloma, which is caused by the reaction of a foreign body in regards to suture material after surgery. Recently, it has been reported as one of the rare complications following surgery, mainly in regards to non-absorbable sutures. The authors hereby report a case along with CT findings and literature review for suture granuloma in the chest wall after lung lobectomy for lung cancer in a 65-year-old woman.

Keywords: Suture Granuloma, Chest Wall, Lung Cancer

Figures and Tables

Fig. 1
65-year-old woman with lung cancer in the left upper lobe and suture granuloma in the left lateral chest wall.
A. Preoperative chest CT scan shows a solitary pulmonary nodule in the left upper lobe (arrow). The lung nodule was pathologically confirmed to adenocarcinoma (T1N0M0).
B. Postoperative follow-up CT scan after 4 months reveals the focal low-attenuated intramuscular lesion with subtle enhancement in the left lateral chest wall (arrow).
C. Postoperative follow-up CT scan after 12 months shows that the intramuscular lesion in the serratus anterior muscle increases in size (arrow).
D. The photomicrograph of the histologic specimen shows the presence of multinuclear giant cells (arrows) with phagocytosis of suture materials (asterisks) [hematoxylin and eosin staining, × 400 (E)].
E. Postoperative follow-up CT scan after 24 months shows that the intramuscular lesion in the serratus anterior muscle decreases in size (arrow).
