Insights
Ceftriaxone, an antibiotic, can cause biliary pseudolithiasis (false gallstones) in children, leading to abdominal pain. Early recognition and cessation of the drug are crucial for symptom resolution.
Area of Science:
- Pediatric Gastroenterology
- Pharmacology
- Medical Imaging
Background:
- Ceftriaxone is a commonly used antibiotic in pediatric patients.
- Biliary pseudolithiasis is a rare adverse effect associated with certain medications.
- Pediatric abdominal pain can have various etiologies, requiring careful diagnostic evaluation.
Purpose of the Study:
- To report a case of ceftriaxone-associated biliary pseudolithiasis in a pediatric patient.
- To highlight the importance of recognizing this adverse drug reaction in children.
- To emphasize the role of ultrasonography in diagnosing biliary pseudolithiasis.
Main Methods:
- A case report of a 5-year-old boy treated with high-dose intravenous ceftriaxone for pneumonia.
- Clinical presentation of abdominal pain following antibiotic administration.
- Diagnostic imaging using abdominal sonography (ultrasound) to evaluate the gallbladder and biliary tree.
- Conservative management of symptoms and monitoring of gallbladder findings.
Main Results:
- The patient developed abdominal pain and was diagnosed with ceftriaxone-associated biliary pseudolithiasis.
- Abdominal sonograms revealed characteristic findings of biliary pseudolithiasis, including hyperechoic bands and sludge.
- Cessation of ceftriaxone therapy led to symptom resolution.
- Biliary findings normalized over time with conservative management.
Conclusions:
- Ceftriaxone, particularly at high doses in children, can induce biliary pseudolithiasis.
- Sonographers should be aware of this potential adverse effect when evaluating pediatric patients on ceftriaxone.
- Prompt recognition and drug discontinuation are key to managing ceftriaxone-induced biliary pseudolithiasis.
Abstract:
A 5-year-old boy who had pneumonia was treated in a neighboring hospital. Ceftriaxone was administrated 2 g/day divided into two equal intravenous doses. After 1 week of ceftriaxone therapy, the patient developed abdominal pain. In our hospital, an abdominal sonogram showed a hyperechoic band with postacoustic shadow within the collapsed gallbladder. He was diagnosed with ceftriaxone-associated biliary pseudolithiasis, and ceftriaxone therapy was ceased. On the 8th our hospital day, he again complained of right abdominal pain after supper. A sonogram revealed high-amplitude echoes within the gallbladder neck and common bile duct. Furthermore, bile duct dilatation was observed. He was managed conservatively, after which the symptoms were resolved. On the 11th day, a sonogram showed only sludge within the gallbladder, and on the 13th day, he was discharged from our hospital. It is important for sonographers to recognize the possible occurrence of biliary pseudolithiasis in ceftriaxone-treated patients, especially when a high dose is used in children.
