case_images: The soft tissue density around the thoracic aorta and the left subpleural area was approximately round or striped, with clear boundaries and uniform density. The larger lesion range was about 5.7cmn1.3cm. (A) chest scan transverse position; (B) Chest scan coronal position.

case_images: The larger lesion measured approximately 5.7cmx1.3cm and showed no abnormalities in the adjacent ribs ( Figure 1 ).
case_images: Contrast-enhanced CT scan of the chest depicted a round and flaky soft tissue density shadow in the thoracic aorta and the left lower pleura area, both with uniform density. The size of the lesion was approximately 6.8roximat The shadow was closely associated with the pleura and exhibited mild enhancement on the enhanced scan, with small blood vessel shadows passing through it. (A) Transverse position CT plain scan; (B) Transection CT scan arterial phase; (C) Transection CT scan venous phase; (D) Coronal position CT scan.

case_images: The size of the lesions increased compared with two years ago, and no abnormal density shadows were observed in the adjacent lung tissue ( Figure 2 ).
case_images: (A, B) The pathological image at magnification; cytoplasmic eosinophilic or clear foam-like histiocytes were observed in some areas, and lymphophagocytosis phenomenon was observed [Panel A -HE(x40), Panel B -HE(x200)]. (C) Immunohistochemistry CD68 positive, CD68(x200).

case_images: Lymphophagocytosis phenomenon was also noted ( Figure 3 ).
case_images: Patient's follow-up findings: two and a half years after surgery. At the patient's most recent follow-up, conducted two and a half years after the surgery, a computed tomography (CT) scan revealed a slight thickening of the left pleura (A) and mild chronic inflammation in the lung tissue surrounding the surgical site (B).

case_images: Chest CT scans revealed mild thickening of the left pleura and minimal chronic inflammation in the lung tissue neighboring the surgical site ( Figure 4 ).
