Diagnosis and treatment of mediastinal cyst using transparietal needle aspiration

The authors present a case report on a 60-year-old female patient suffering from benign mediastinal cyst, arterial hypertension and porphyria. CT-guided transparietal fine-needle punction was done simultaneously as a diagnostic and a therapeutic procedure. Partial regression of the cyst was still apparent at the check CT investigation after six months. The examination of the level of immunoglobulins in the fluid obtained during transparietal punction confirms the diagnosis of bronchogenic cyst.
