Date: 26 November 2013

Ct scan of chest. This patient with severe ABPA, serologically and radiologically, developed a spectrum of lesions in the lung. In this cut, a cavitating infiltrate in the anterior segment of the left upper lobe was visualised together with some bronchial thickening and bronchiectasis in the left upper and lower lobe.
