Bilateral absence of the pectoralis major muscle with accompanying abnormalities of shoulder muscles has been reported in patients without Poland anomaly (PA). However, symmetric absence of pectoralis major muscles, hypoplasia of breasts and nipples with symmetric chest wall deformity and bilateral hand anomaly has not previously been reported. A 6-year-old girl with bilateral absence of pectoralis major muscles and hand involvement and symmetric chest wall deformity is, to our knowledge, the first known case of bilateral Poland anomaly.

The greatest difficulty in the CT diagnosis of perforated pulmonary hydatid cyst (PPHC) is the increase in the attenuation numbers following infection. Because of the solid density of infected hydatid cysts, the differentiation from an abscess or neoplasm is usually impossible. The aim of this study was to evaluate the value of "air bubble" as a new CT sign in the diagnosis of PPHC. Sixty-five patients (28 men and 37 women) with PPHC were included in the study. As a control group, 55 patients who had malignant (n = 36) or non-malignant (n = 19) pulmonary diseases were also examined. Radiological diagnosis with classical CT findings was made in only 38 of 65 patients (58.5 %) with PPHC. Air bubble sign was positive in 54 of the patients with PPHC (sensitivity 83.1 %) but only 3 of 55 patients in control group (specificity 94.5 %). When we analyzed the CT scans with classical CT findings including air bubble, the diagnosis of PPHC was made in 61 of patients (93.8 %). It is concluded that "air bubble sign" is a valuable CT finding in the diagnosis of PPHC.

A rare case of acromesomelic dysplasia is reported. The radiological findings were consistent with shortness of all tubular bones, especially those of the forearms. There was also evidence of mild lumbar spine stenosis.

The association of Wilms tumor (WT) and vertebral disorders, such as hemivertebrae or fusion anomalies, have been described in literature. Here, we report a rare association of butterfly T3, T8 vertebrae and a T2, T7 hemivertebrae in a patient with WT, determined during initial examinations of tumoral extension. In patients with WT, investigation of vertebral malformations should be a part of diagnostic work-up.
