case_images: The chest radiograph (Figure 1) revealed a well-demarcated, non-cavitating, 3 cm in diameter peripheral opacity in the left lower lobe, with obtuse angles between the lesion and the pleura, and no other abnormalities.
case_images: Chest computed tomography (CT).

case_images: Chest computed tomography (CT), (Figure 2) confirmed a 3 x 4 cm, oval-shaped, well-delineated peripheral mass in the left lower lobe, abutting the pleura, homogenous in attenuation and no evidence of mediastinal or axillary adenopathy.
case_images: Section of the lung lesion (Hematoxylin and Eosin stain x 40): In this section, the morphology of a spindle cell neoplasm is apparent, with slit-like spaces and normal adjacent lung parenchyma.
