The objective of this article is to present a case of Ceftriaxoneinduced biliary pseudolithiasis in a pediatric patient with a diagnostic approach that takes into consideration the combination of clinical-imaging methods. Case presentation: We present a clinical case of a healthy 9-year-old school boy who experienced non-specific abdominal pain for 11 days and was evaluated at Batista de Sousa Hospital. São Vicente Island, Cape Verde. The mother refers that she has presented unquantified febrile sensation. The clinical-imaging findings suggest appendicular plastron, for which an antibiotic plan with Ceftriaxone is decided. On the 14th day of the administration of Ceftriaxone she added constant pain in the right hypochondrium, so a diagnosis of Ceftriaxone-induced biliary pseudolithiasis was made. Conclusion: The combination of the clinical-imaging methods pave the way for an accurate diagnosis of Ceftriaxone-induced biliary lithiasis disease in children under the premise that this drug should be used with caution.
