General Pulmonary Symptoms

      • Usually have bizarre, irregular, or dimpled shape
      • May be multi-loculated
      • Location: lower lobe predilection (R>L side)
      • Calcification: may occur around periphery or within cyst (calcification does not occur in pyogenic abscess, aiding in differentiation from this entity)
      • Cavitation: common
    • Fine Needle Aspirate: diagnostic

Treatment

Anti-Parasitic Agents

Aspiration of Cyst with Infusion of Hypertonic Saline, 95% Alcohol, or 10% Peroxide

Surgical Resection

  • May be used with albendazole
