Abstract:
We present a rare case of intimal sarcoma (IS) that is presumed to have arisen simultaneously from both pulmonary arteries. A 61-year-old man presented with worsening exertional dyspnea. After examination, he was suspected of having chronic thromboembolic pulmonary hypertension (CTEPH). PET/CT revealed mass-like FDG accumulation in both pulmonary hila (SUVmax = 13.80 on the right, 24.68 on the left) without any continuity. A pulmonary artery biopsy was performed and confirmed the diagnosis of IS, which was thought to arise simultaneously from the left and right pulmonary arteries.
