Chemotherapy-Associated Pneumatosis Intestinalis

A 65-year-old woman underwent surgery for squamous cell carcinoma of the left tonsil (pT2pN1M0) requiring adjuvant radiotherapy and chemotherapy (cisplatin). After the second cycle of chemotherapy, the patient arrived at the Emergency Department complaining of dysphagia, dyspnoea, and cervical subcutaneous emphysema, with unremarkable abdominal examination and laboratory tests. Contrast- enhanced cervico-thoraco-abdominal CT scan with oral and intravenous contrast (fig. 1 and 2) revealed cervical and thoracic subcutaneous emphysema, pneumomediastinum, pneumoperitoneum, retropneumoperitoneum and pneumatization of the colon wall (pneumatosis coli), without free intra-abdominal fluid. Conservative treatment was established with corticosteroids, antibiotics and parenteral nutrition1-2. She presented progressive reduction of emphysema and radiological resolution of ectopic air. Oral diet was progressively reintroduced, and the patient was uneventful discharged from hospital3-4. This case-report highlights the importance of considering the possibility of a benign chemotherapy-associated pneumatosis intestinalis to avoid unnecessary surgical intervention5
