Pulmonary lymphangioleiomyomatosis (PLAM) is an indication for lung transplantation (LTx). Angiomyolipomas occur in approximately 50% to 60% of patients with PLAM. We describe a patient presenting with hemoptysis post-LTx for PLAM. Computed tomography (CT) scan demonstrated no pulmonary abnormality, but identified a retroperitoneal mass confirmed as angiomyolipoma by CT-guided core biopsy. Based on experimental work that rapamycin may inhibit angiomyolipoma cells, we commenced the patient on low-dose rapamycin. She had no adverse reactions and follow-up CT scan after 7 months demonstrated almost complete resolution of the tumor. This suggests a role for rapamycin in routine post-LTx immunosuppression for PLAM.
