[Chronic benign Pneumatosis intestinalis].

We present the case of a 63-year-old male patient free of complaints with oncological follow up examination after renal cell carcinoma (RCC) who presented extent air in the intestinal wall. The computed tomography showed a pronounced pneumatosis intestinalis with punctum maximum in the part of left and less right colon flexure. Free air as a sign of perforation was not found. Retrospectively, the pneumatosis intestinalis was found in fluctuating extent in several preliminary CT and MRI investigations. Repeated colonoscopies with histologic sampling were unremarkable. Due to the long-term findings, the patient was treated conservatively. A cause for the pneumatosis was not finally identified. Our presented case demonstrates that pneumatosis intestinalis coli can persist over a long period of time and could be a chronic phenomenon. Nevertheless, exclusion of an acute cause of pneumatosis is mandatory in each case. If chronic benign pneumatosis intestinalis coli is considered, a continued interdisciplinary workup and patient support is necessary.
