Characteristic of pancreatic involvement in melioidosis: Case report and literature review.

BACKGROUND

Intra-abdominal abscesses are a frequent manifestations of melioidosis whereas pancreas is barely affected by this condition. Herein, by delving into the clinical manifestations, diagnostic processes, and the ultimate clinical outcome, we report a case of an unusual presentation of pancreatic melioidosis in a Chinese patient, aiming to shed light on a diagnosis that is not commonly associated with the pancreas.

CASE PRESENTATION

The patient, a 32-year-old male farmer, suffered from persistent burning pain in his upper abdomen, accompanied by nausea, vomiting, fever and other symptoms, presented to the clinic. His body temperature spiked to 38.5 °C without apparent reason for this fever. A thorough examination, including the blood culture and the imaging examination, led to a diagnosis of pancreatic melioidosis. The patient was promptly treated with intravenous meropenem and ceftazidime. As a consequence, his symptoms eased and discharged in stable condition. The patient continued his treatment with oral trimethoprim-sulfamethoxazole (co-trimoxazole) for three months to control the infection. Following 6 months of regular follow-up, the patient fully recovered.

CONCLUSIONS

In tropical regions such as Hainan, it is crucial to consider atypical infection like in the differential diagnosis, even when they present in atypical locations such as a pancreatic pseudocyst. Detecting pancreatic involvement in melioidosis relies heavily on sensitive bacterial culture and imaging examination. This retrospective study of patients' infection diagnosis aims to shed light on the clinical treatment, and prognosis associated with pancreatic melioidosis, thereby raising awareness about the risk of pancreatic affection in melioidosis cases.
