[Nephrobronchial fistula].

Area of Science:

• Nephrology
• Pulmonology
• Radiology

Background:

• Nephrobronchial fistula is an uncommon complication arising from renal inflammatory conditions.
• The condition involves an abnormal connection between the kidney and the bronchial tree.

Observation:

• Clinical presentation is variable, with pulmonary symptoms frequently overshadowing renal signs.
• Cough, hemoptysis, and calculus expectoration are rare presenting symptoms.
• The case highlights subcutaneous tissue infection as a prominent sign due to concurrent fistulization.

Findings:

• Diagnostic tools include chest and abdominal X-rays, fistulography, retrograde pyelography, and computed tomography (CT) scans.
• CT scans are particularly valuable for evaluating pararenal abscesses.

Implications:

• Early recognition and accurate diagnosis are crucial for managing this rare pathology.
• Understanding the diverse clinical presentations, especially pulmonary manifestations, is key for timely intervention.
• Advanced imaging techniques like CT play a vital role in comprehensive assessment and treatment planning.
