Ruptured Pulmonary Hydatid Cyst (CT).

PROCEDURE: Axial CT sections of the chest were obtained before and after injection of intravenous contrast in a multidetector CT scan followed by Multiplanar reconstructions.

FINDINGS:

-Evidence of diffuse opacity involving almost the whole anterior segment of the left upper lobe with evident air bronchgram inside its parenchyma with a single cavity measuring about 33 x 20 mm with collapsed irregular walls in addition to multiple small bronchiectatic changes. It causes shift of the mediastinum and heart to the same side suggesting underlying collapse of the affected lobe.
-The lingula of the left lung shows evidence of mixed density mass with diameters of about 45 x 46 mm in diameters with multiple cystic areas.
-A big hepatic cystic lesion is noted in the right lobe of the liver measuring about 9 x 9.5 cm in diameters with multiple internal locules and septation.
-Another two smaller lesions were observed in the right hepatic lobe and in the caudate lobe.
-Airway: Normal
-Lung parenchyma: The rest of the left lung and the whole right lung parenchyma is normal.
-Pleura: No pleural effusion, thickening, or pneumothorax
-Thoracic aorta and great vessels:  Normal in diameter
-Pulmonary arteries: Normal
-Heart and pericardium: Normal
-Lymph nodes: No enlarged thoracic lymph nodes
Thoracic spine: Normal
-Chest wall: Normal
-Small gall bladder (non fasting condition) with no definite calculi inside its cavity.
-Portal vein is normal.
-The spleen, pancreas and adrenals are normal.
-The kidneys are normal in size. No evidence of any focal mass lesions. No evidence of dilatation of collecting systems. No evidence of calculi.
-The urinary bladder is well distended and shows no obvious mass lesion in it.
-The bowel loops are normal in caliber, location and show normal wall thickness.
-No evidence of ascitis is seen.

IMPRESSION:

• Picture is suggestive of multiple hepatic and pulmonary hydatid cysts.
• The lesion seen in the left anterior segment of the left upper lobe could represent a ruptured hydatid cyst resulting in consolidation collapse.
• For clinical and laboratory correlation.
