Hepatogastric fistula: a complication of pyogenic liver abscess in a patient with the Brugarda syndrome - A rare case report.

UNLABELLED

Hepatogastric fistula following pyogenic liver abscess (PLA) is a rare and fatal complication, and only a handful of cases have been reported without co-existing comorbidities of Brugarda syndrome.

CASE PRESENTATION

A 22-year-old male presented to the emergency room with a known case of Brugarda pattern ECG with chief complaints of on-and-off abdominal pain and fever for 2 weeks and shortness of breath for one day. On evaluation, echocardiography showed a clot in the inferior vena cava (IVC) and right atrium (RA), and on computed tomography scan of the abdomen revealed a liver abscess with transmural gastric perforation. During, an exploratory laparotomy where a fistula joining the left lobe of the liver and stomach was detected, and an emergency excision was done. The patient was shifted to the ICU and later developed septic shock, which was managed medically.

CLINICAL DISCUSSION

Usually, thrombosis of the portal vein and the hepatic vein is a very common complication of a PLA but vascular complications like IVC, RA thrombosis, and hepatogastric fistula have been reported rarely. Our case is peculiar hepatogastric fistulization along with IVC/RA clots in a patient with Brugarda pattern ECG. The typical clinical manifestation of a patient with hepatogenic fistula is absent in our patient and presented with an on-off type of fever, epigastric pain, and shortness of breath and was managed surgically.

CONCLUSION

Hepatogasric fistula, thrombosis of the IVC, and RA are a rare complications of PLA. The patient with Brugarda syndrome is at high risk as its clinical manifestation gets exaggerated during sepsis.
