TL;DR
This paper reports the first case of a rare condition where two uncommon pleural effusions occurred together in a patient with multiple myeloma.
Contribution
The paper presents the first documented case of concurrent urinothorax and myelomatous pleural effusion.
Findings
An 81-year-old man with multiple myeloma had both urinothorax and myelomatous pleural effusion.
A pelvic extramedullary plasmacytoma caused obstructive uropathy and pleural involvement.
The case highlights the need for multidisciplinary evaluation in complex pleural effusions.
Abstract
Myelomatous pleural effusion (MPE) is a rare complication of multiple myeloma, occurring in < 1% of cases and associated with poor prognosis. Urinothorax, another rare cause of pleural effusion, results from urine leakage into the pleural cavity, typically due to obstructive uropathy or trauma. Although both conditions are individually uncommon, their concurrent occurrence has not been previously reported. An 81‐year‐old man with relapsed multiple myeloma presented with dyspnea, hematuria, and acute renal failure. Imaging revealed bilateral hydronephrosis, obstructive uropathy from a pelvic mass, and bilateral pleural effusions. Thoracentesis showed an exudative, hemorrhagic effusion with a pleural fluid‐to‐serum creatinine ratio > 1, initially suggesting urinothorax. Despite bilateral nephrostomy, the effusion recurred. Cytology and immunohistochemistry confirmed MPE. Biopsy of the…
