A 22 year old female presented to us with cough and fever. Frontal chest X-Ray revealed multiple round radiopacities in left apex. An ultrasound and contrast enhanced CT were also done.
What is your diagnosis ?
Ultrasound study reveals cystic space occupying lesions.
PULMONARY HYDATID CYSTS
Ultrasound study reveals cystic space occupying lesions. These lesions show posterior acoustic enhancement and were multiple. On contrast enhanced CT, multiple round hypodense (near water density) space occupying lesions are seen in left apex. The lesions are smoothly outlined and show mild peripheral contrast enhancement. ELISA was positive and surgical exploration proved them to be hydatids.
Hydatid cysts are caused by the larval stage of either Echinococcus Granulosus or E. Alveolaris. Balikian et al in 1974 extensively studied the characteristic of hydatids in lung. They found cysts to be multiple in 30% and bilateral in 20% cases. Lower lobe involvement was seen in 60% and a predilection for right lobe and posterior segments was also seen. Calcifications in lung hydatid is rare. Perizel et al in 1984 emphasised that visualization of daughter cysts is characteristic. Hoff et al in 1987 noted that walls of cysts may demonstrate marked contrast enhancement on CT (H.U. of cyst fluid is 3-30 H.U.) .
