case_images: f1-imcrj-10-275
case_images: The chest x-ray revealed a large left sided pleural effusion (Figure 1).
case_images: Computed tomography scan of the chest showing left sided lung mass.

case_images: f2-imcrj-10-275
case_images: On noncontrast computed tomography of the chest, a large heterogeneously enhancing left lung mass with pleural effusion was seen (Figure 2), so ultrasound-guided fine needle aspiration cytology was advised for further diagnosis.
case_images: (A) An immunohistochemical stain for BCL-2 performed on the biopsy specimen. (B) An immunohistochemical stain for CD34 performed on the biopsy specimen.

case_images: f3-imcrj-10-275
case_images: On immunohistochemistry analysis, the specimen was immunoreactive to BCL-2 and CD34. (Figure 3A and 3B) Chromogranin A and Synaptophysin were nonimmunoreactive.
case_images: Surgical resection of tumor through left lateral thoracotomy approach.

case_images: f4-imcrj-10-275
case_images: A left lateral thoracotomy was performed for resection of the pleural mass. (Figure 4) A large tumor originating over the surfaces of the left lower and middle lobe was found, and this was not invading fissure and lingula.
case_images: Gross specimen of the SFT of left lung which is well circumscribed, encapsulated, and measuring 12x10x8 cm in size.. Abbreviation: SFT, solitary fibrous tumor.

case_images: The tumor was well circumscribed and encapsulated, measuring 12x10x8 cm in size. (Figure 5) True hypoglycemia, low insulin and c-peptide, and resolution of hypoglycemia after resection of a tumor confirmed solitary fibrous tumor (SFT) with Doege-Potter syndrome (DPS) as the etiology of hypoglycemia.
