Abstract
Intestinal pneumatosis (IN) is an uncommon radiological finding defined as the accumulation of air in the gastrointestinal tract wall. Its clinical signs are nonspecific and include symptoms such as diarrhea or abdominal pain. It includes benign entities (with subtle symptoms and the accumulation of air in the form of cysts that appear as clustered nodular lesions on the endoscopy, collapsible and soft); or severe cases (symptoms indicative of general health compromise and linear accumulation of air or free fluid suggestive of hollow viscus perforation); which require different management. We present the case of a patient diagnosed with benign intestinal pneumatosis (BIN), associated with anatomical changes due to a diaphragmatic hernia. CASE REPORT We report the case of an 86-year-old woman with a Morgani-Larrey congenital diaphragmatic hernia (HML) (2) admitted due to exacerbation of chronic baseline diarrhea. A colonoscopy with biopsies was performed, but the study was incomplete due to colonic torsion at the hepatic angle deriving from HML, with uncomplicated colonic mucosa and absence of cystic nodulations. Figure 1a. Biopsies ruled out organicity. The abdominal computed tomography (CT) scan performed revealed the accumulation of pneumoperitoneum bubbles in the distal ileum and suprahepatic wall without identification of continuity changes, or signs of visceral perforation. Figure 1b-c. The patient was diagnosed with BIN associated with an anatomical change (HML). Medical treatment was initiated with metronidazole at a dose of 1500 mg/day for 1 week, along with the patient's usual probiotics, and commercial compounds containing xyloglucan (pea protein) to restore the intestinal barrier function. (3). The patient was discharged with complete resolution of the diarrhea. No surgical intervention for her HML was required. DISCUSSION The clinical and radiological data in the presence of IN help us differentiate between severe cases and BIN, the latter being managed conservatively without the need for medical or surgical treatment. The intestinal barrier restoration measures implemented in our patient may have contributed to this resolution, although there is not enough scientific evidence to support this. The endoscopic image of nodular cysts is not always present in these cases, and the diagnosis of choice for this condition is radiological and based on exclusion. (4)
