It is a self-limiting inflammatory process and resolves spontaneously. In addition to clinical features, ultrasonography is the primary diagnostic modality. We aimed to evaluate the clinico-radiological characteristics of mesenteric adenitis in patients presenting with abdominal pain. Materials and Methods: A total of 108 patients attending paediatric out-patient and paediatric surgery clinic in Saveetha Medical College and Hospital, Chennai, between January 2018 and December 2020 with abdominal pain for several aetiologies were included in this study. The clinical presentation, laboratory parameters and the ultrasonographic findings were noted. Data summarized as numbers, percentages and Mean ± Standard Deviation (SD). Results: Peak prevalence was found to be at around 8 [range 6-10] years. Clinically, 58.3% had fever, 40.7% had dysuria and 36.1% had diarrhoea. Laboratory parameters were non-specific for Original Research Article
