“…Ward et al also observed the signs of PX on the PA chest radiograph, in a series of 72 patients. Similar to our study, they also assessed the straight left heart border, increased opacification of the right medial lower zone, indistinct right heart border and rib alignment changes.…”

Introduction Pectus excavatum (PX) denotes a concavity of the sternum and is the most common chest wall deformity. Many characteristic signs have been described on frontal chest radiographs including increased density of the inferomedial right lung, blurring of the right heart border, steeply angled anterior ribs, horizontal posterior ribs, straight or convex left heart border and loss of silhouette of the descending thoracic aorta. These signs are often subtle and rarely all present in any individual. We describe a further sign in women with PX, the medial breast margin sign. This sign consists of more sharply defined and more vertically oriented medial breast borders on frontal chest radiographs than in those of women with normal chest wall morphology. This study aims to document the sensitivity, specificity and inter‐observer reliability of the new sign, and compare with that of the previously described signs in patients with varying degrees of PX. Methods The frontal chest radiographs of 185 women with PX and 50 women with normal chest wall morphology were assessed by two reviewers for the presence of the new sign and previously described signs. All the signs had their sensitivity, specificity and inter‐observer reliability calculated. Results The new sign had a sensitivity of 0.48, a specificity of 0.96 and inter‐observer reliability of κ = 0.79, ranking third, second and first among all other signs, respectively. Conclusion The medial breast margin sign is useful in diagnosing PX and is comparable to the previously described classic signs.

“…The condition is uncommon in African Americans and Latinos . The male‐to‐female ratio is said to be as high as 5:1, although Ward et al found a female predominance with 53 out of 72 patients being women. Our anecdotal experience in adults also suggests a higher incidence of PX in women than men in our population.…”

“…A SLHB may also indicate a previous left lower lobectomy [24]. Pectus excavatum is also a cause of a straight left heart border, caused by a shift in the heart to the left, with a further feature being an indistinct right heart border [25, 26]. A SLHB has not been previously described to be associated with the presence of a hemopericardium.…”
