title: [Chronic benign Pneumatosis intestinalis].
abstract: History and clinical findings: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.Investigations and diagnosis: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.Treatment and course: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.Conclusions: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.
