Formation of an aneurysm in the sinus of Valsalva of the aortic root is usually due to an area of congenital weakness in its wall. This aneurysm may progressively dilate and rupture into any of the cardiac chambers or into the pericardial cavity. Though this is conventionally treated by surgery, interventional therapy using various closure devices is becoming more common. Embolization of these closure devices may occur. We report a case of embolization of such a device into the left pulmonary artery which during surgical retrieval, unmasked the hidden ventricular septal defect (VSD). Therefore one has to be cautious while making a diagnosis of rupture of the sinus of Valsalva of right coronary sinus without VSD.

Echinococcosis is a ubiquitous zoonosis. The causal organism is a flat tapeworm whose larval form causes infestations in human beings, who are its accidental hosts. It is known to occur in all parts of the body with the highest incidence in the liver, followed by the lung. Hydatid cysts in the neck are rare by themselves. We report a case of hydatidosis of the lung and central compartment of the neck, in a man who presented with pulmonary symptoms only. Computerized tomogram of the chest had revealed a hydatid cyst in the left lung and another incidental hydatid cyst in the neck. He underwent successful excision of both the cysts in one sitting.
