CTICasesRadiation-Induced Necrotic Pulmonary Sloughing
Imaging findings
CT chest in a patient post-definitive chemo-radiation for lung cancer shows a large, pre-existing cavitary lesion that has developed a new fluid-debris level with irregular, sloughed internal soft tissue elements, mimicking tumor progression or abscess.
Key takeaways
Definitive radiation therapy for lung cancer can induce ischemic necrosis of the tumor and surrounding parenchyma. This can cause necrotic, sloughed lung tissue to fall into the cavity, presenting as mobilizable debris on CT. Recognizing this benign radiation-induced sloughing is important to avoid misdiagnosing active infection or tumor recurrence.
