Severe emphysematous pyelonephritis mimicking intestinal obstruction

Tubercular empyema a sequalae of emphysematous pyelonephritis with porous diaphragm syndrome and its successful management: A case report

Introduction

Emphysematous pyelonephritis (EP) is a life-threatening renal disease requiring early and immediate therapy. EP resulting in tubercular empyema is unusual, with no reports to date.

Presentation of case

A 50-year-old female in sepsis diagnosed with diabetes mellitus on insulin presented with recurrent abdominal pain radiating to the left side of her back for one month and recurrent episodes of vomiting and fever for one week. Her contrast-enhanced computed tomography showed emphysematous pyelonephritis (EP), ruptured splenic abscess, disrupted and eventrated left diaphragmatic lining, pleuroperitoneal communication, and a left empyema. Genexpert studies for pleural pus revealed Mycobacterium tuberculosis. Her deteriorating condition required surgical intervention in the form of decortication, sterilization of the thoracic cavity, and composite mesh placement for the diaphragmatic porous syndrome.

Conclusion

This case report demonstrates the rare and aggressive presentation of EP, its sequelae, and successful management with composite mesh to prevent recurrent intrathoracic infection secondary to porous diaphragm syndrome.

•

Emphysematous pyelonephritis leading to tubercular empyema is rare

•

Pathogenesis is explained by cascades of reaction

•

Composite mesh placement prevents porous diaphragm syndromes

Point-of-care ultrasound for the early diagnosis of emphysematous pyelonephritis: A case report and literature review

BACKGROUND

Emphysematous pyelonephritis (EPN) is a rare but fatal necrotic infection of the kidney, which usually leads to septic shock. Therefore, early diagnosis and optimized therapy are of paramount importance. In the past two decades, point-of-care ultrasound (POCUS) has been widely used in clinical practice, especially in emergency and critical care settings, and helps to rapidly identify the source of infection in sepsis. We report a rare case in which a “falls” sign on POCUS played a pivotal role in the early diagnosis of EPN.

CASE SUMMARY

A 57-year-old man presented with fever and lumbago for 3 d prior to admission. He went to the emergency room, and the initial POCUS detected gas bubbles in the hepatorenal space showing a hyperechoic focus with dirty shadowing and comet-tail artifacts. This imaging feature was like a mini waterfall. His blood and urine culture demonstrated Escherichia coli bacteremia, and EPN associated with septic shock was diagnosed. The patient did not respond to broad-spectrum antibiotic treatment and a perirenal abscess developed. He subsequently underwent computed tomography-guided percutaneous catheter drainage, and fully recovered. We also review the literature on the sonographic features of POCUS in EPN.

CONCLUSION

This case indicates that a “falls” sign on POCUS facilitates the rapid diagnosis of severe EPN at the bedside.
