6-year-old male status post biopsy, resection, and chemotherapy for alveolar rhabdomyosarcoma. Off therapy evaluation. LUNGS AND PLEURA: The previously described cluster of nodular and scarlike opacity in the right upper lobe appears stable. Likewise, the nodular opacity at the lateral aspect of the right major fissure is unchanged.Ill-defined nodular and tree in bud opacity in the left lower lobe is stable in appearance (image 38/65). No pleural effusions or focal consolidation are seen.MEDIASTINUM AND HILA: Evaluation of lymph node pathology is limited without intravenous contrast. Within this limitation, small pretracheal lymph nodes appear similar in size. No grossly enlarged mediastinal or hilar lymph nodes are evident.The heart size is within normal limits, with no evidence of pericardial effusion.CHEST WALL: A surgical clip is again seen in the right axilla. No pathologically enlarged axillary lymph nodes are seen. No chest wall lesions are evident.No destructive bone lesions are seen.UPPER ABDOMEN: Incomplete views of the upper abdomen are limited by the noncontrast protocol used for the exam. Within this limitation, the previously described subcentimeter round hypodense lesions are not well visualized now. One hypodense subcentimeter lesion in the dome is too small to characterize on image 51/65.
1. Stable left upper lobe nodular opacity, likely post infectious in etiology.2. Stable right upper lobe nodules and scar.3. Small liver dome hypodensity too small to characterize.
