Chronic intestinal pseudo-obstruction with pneumatosis cystoides intestinalis in a patient with systemic sclerosis

<jats:title>Abstract</jats:title> <jats:sec> <jats:title>Rationale:</jats:title> <jats:p>Chronic intestinal pseudo-obstruction (CIPO) and pneumatosis cystoides intestinalis (PCI) are rare abdominal diseases and the pathological mechanisms have not been fully elucidated. Systemic sclerosis (SSc), which is characterized by the progressive sclerotic changes of skin and internal organs, is a refractory collagen disease and is frequently associated with digestive disorders including CIPO.</jats:p> </jats:sec> <jats:sec> <jats:title>Patient concerns:</jats:title> <jats:p>A 68-year-old woman who has been well managed for SSc over the long term, who presented with abdominal fullness for the first time.</jats:p> </jats:sec> <jats:sec> <jats:title>Diagnoses:</jats:title> <jats:p>Abdominal X-ray and computed tomography (CT) images showed PCI with pneumoperitoneum findings. Based on the diagnosis of CIPO, we evaluated the intestinal peristalsis of the patient by using cine magnetic resonance imaging (MRI).</jats:p> </jats:sec> <jats:sec> <jats:title>Interventions:</jats:title> <jats:p>Oral medications of 15 g/d of Daikenchuto, 750 mg/d of Metronidazole and Sodium Picosulfate were started for improving the bowel peristaltic movement and decreasing intestinal gas production.</jats:p> </jats:sec> <jats:sec> <jats:title>Outcomes:</jats:title> <jats:p>A great improvement of CIPO and PCI by multidrug therapy without any surgical treatments for such an unusual case.</jats:p> </jats:sec> <jats:sec> <jats:title>Lessons:</jats:title> <jats:p>This case indicates that SSc can be accompanied with not only CIPO but also PCI as digestive disorders and that cine MRI, which is a definitely beneficial imaging modality, can intelligibly visualize the peristalsis of the intestines and lead to successful medical control by noninvasive treatment.</jats:p> </jats:sec>
