AimThe aim of this study is to increase the understanding of pneumatosis cystoides intestinalis (PCI) and its incidents.MethodWe report here a case of PCI in an 88-year-old man with a provisional diagnosis of perforated viscus and possible ischaemic bowels based on CT findings of pneumoperitoneum. The patient was found to have extensive PCI on his small bowels. We then systematically search the PubMed database for case reports for articles containing ‘pneumatosis intestinalis’ in their titles or key words.ResultsThe study group consisted of 52 cases on PCI from the period of 2010–2014 with the focus on the adult population. The youngest patient was 18 years old and the oldest was 91 years old. The mean age was 60.4 years (range, 18–91 years old). There were 27 (52 %) females and 25 (48 %) males. The most common symptoms were abdominal pain (79 %) followed by nausea/vomiting (27 %) and abdominal distension (19 %). CT imaging was the most common investigation modality used (94 %). Three (6 %) of the patients had laparoscopic treatment while 20 (38 %) had laparotomy. Thirty-six (69 %) of them recovered uneventfully while 9 (17 %) of the patients died.ConclusionAlthough there have been more case reports published on PCI in the recent years, the understanding of this condition remains in the infancy stage. PCI can be difficult to diagnose and can be easily misdiagnosed as pneumoperitoneum in an acute abdomen. Often it is identified incidentally during operation. Asymptomatic PCI should be treated conservatively, while emergency laparotomy should be reserved for life threatening abdominal pathology.
Infectious enterocolitis caused by shigella is usually self-limiting and seldom requires antibiotics treatment. It is uncommon to develop fulminant shigellosis requiring surgery. We report a rare case of fulminant shigellosis in a HIV patient with recurring infection which could not be managed with intravenous antibiotics. CT reviewed extensive colonic wall thickening and stranding with evidence of pneumatosis coli. The patient eventually required a Hartmann procedure. Although fulminant shigellosis is uncommon, thorough assessment and vigilant management are warranted in immunosuppressed patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
