Complicated giant diverticulum of the transverse colon accompanied by right inguinal hernia of the greater omentum.

Giant colonic diverticulum is a very rare entity in colonic diverticular disease and is characterized by a high rate of complications such as perforation, abscess formation and even carcinoma. We report a case of a complicated giant diverticulum of the transverse colon accompanied by a right inguinal hernia of the greater omentum in a 52-year-old man, as demonstrated on CT.

Carcinoma originating from aberrant breast tissue of the right upper anterior chest wall : a case report.

Aberrant breast tissue is usually found in proximity to the normal breast, that is, in the axillary, sternal or clavicular regions. Carcinoma occurs more frequently in the aberrant tissue of the axilla than the extra-axillary site though the overall incidence of tumors of aberrant breast tissue is low. To our knowledge, studies regarding the carcinoma of aberrant breast tissue of the extra-axillary site have been reported rarely. Here we report a recent case of carcinoma originating from the extra-axillary aberrant breast tissue, presenting as a subcutaneous nodule on the right upper anterior chest wall. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be suspected for breast carcinoma as a differential diagnosis and treated properly.

Tibial plateau erosions associated with lateral meniscal cysts.

Although meniscal cysts are common, erosions of bone caused by these cysts are quite rare. We report MR imaging findings of two cases in which lateral meniscal cysts resulted in erosion of the lateral tibial plateau.
