Abstract:
Traumatic pulmonary pseudocysts (TPPs) are rare but clinically relevant complications of thoracic trauma, often misdiagnosed due to their non-specific presentation and resemblance to other cavitary pulmonary lesions. We report the case of a 26-year-old male presenting with delayed symptoms following a fall, ultimately diagnosed with multiple TPPs via thoracic CT scan. The patient experienced a favourable evolution with conservative management, including aerosolized tranexamic acid for minor hemoptysis. This case highlights the importance of thorough clinical history-taking and imaging in establishing the diagnosis, avoiding unnecessary antibiotic therapy, and limiting hospitalization. TPPs generally resolve spontaneously, but complications such as infection or hemorrhage may require intervention. Early recognition and tailored management are essential to optimize outcomes.
