Cyst – US
Ultrasound of a large kidney cyst.
Cystitis
Cyclophosphamide Induced Cystitis
Cyclophosphamide induced cystitis. This patient presented with gross hematuria after recent treatment with cyclophosphamide. Cyclophosphamide is excreted by the kidney. The direct contact with the bladder mucosa leads to cystitis. Approximately 10% of patients on this drug have this complication. The figure rises to 40% for those patients receiving high-dose treatment.
Wegeners Granulomatosis

Pulmonary Contusion
In this patient, note the irregular, soft, fluffy opacification at the right heart border suggestive of a medial right lower lobe pulmonary contusion.
Bronchogenic Carcinoma
Ill-defined infiltrating lesion in left hilar region.
Active Tuberculosis
Cavitation in apical regions and posterior segments of upper lobe plus or minus calcification. [courtesy of Dr. M. Hutcheon]
Tension Pneumothorax
In addition to the features of an uncomplicated pneumothorax, note the marked mediastinal shift to the left in this young patient with a right tension pneumothorax.
Pneumothorax – Pleural Disease
The patient’s left pneumothorax is more difficulty to diagnose on this supine film. This study demonstrates the “deep sulcus” sign, with the left costophrenic sulcus descending below the edge of the film. Other clues include a hyperlucent left hemithorax and slight sharpening of the left mediastinal border. This patient also has a tracheostomy, evidence of a prior sternotomy (not the multiple circular sternal wires), and a central venous catheter with its tip in the right ventricular outflow tract. The circular structures projecting over the chest, some with wires extending from them are ECG leads.
