A 14-year-old boy presented with upper backache and a painful swelling in the right paraspinal region for 7 days. He had no history of trauma. MRI showed a non-specific ill-defined heterogeneous lesion, which showed intense postcontrast enhancement. Ultrasonogram showed a peripheral sheet of calcification around the lesion. A CT scan showed a faint rim of calcification, which increased in thickness over weeks, confirming the diagnosis as myositis ossificans. We present our approach to the case and also review the imaging features of different stages of the disease process and their differentials.

Poland's syndrome is a rare congenital anomaly characterised by partial or complete absence of sternocostal head of pectoralis major muscle and anomalies of ipsilateral hand and digits. Other associated anomalies involving anterior thoracic wall, breast, diaphragm and vertebrae have also been reported in various cases. We report a case of a 10-year-old girl, with features of left-sided Poland's syndrome associated with spina bifida, dextroposition of the heart and left-sided diaphragmatic hernia. These are rare associations of Poland's syndrome. She was investigated with chest X-ray, contrast-enhanced CT of the thorax, ultrasonography of abdomen and echocardiography which helped in arriving at an accurate diagnosis and assessing all the associated abnormalities.

SUMMARYA 27-year-old man road traffic accident victim, in his initial CT, showed fractures in left lower ribs, pleural effusion and splenic and pancreatic lacerations. The left pleural effusion, drained with an intercostal tube, did not show any significant reduction in size and pleural fluid amylase was abnormally high. A diaphragmatic tear was suspected. Contrast was injected through the intercostal tube and a CT was performed, which revealed a small diaphragmatic tear and communication of the pleural space with peritoneum and the pancreatic laceration site.
