ABSTRACT
We report the unusual ultrasound appearance of coalescent otomastoiditis with subperiosteal abscess in a 3-month-old boy with a 1-week history of an enlarging lump behind the left ear. Ultrasound examination of the lump revealed subcutaneous oedema with an abscess extending from a defect in the cranial vault as a result of extension of the inflammatory process. We believe that this sonographic appearance has not been previously described in the published literature.

Cystic dysplasia of the rete testis (the network of straight seminiferous tubules within the mediastinum testis leading to the efferent ductules) is a rare congenital anomaly. There are only 15 cases reported in the literature to date and only one report of the US findings [1-5]. This report highlights the characteristic appearance of the lesion on ultrasound examination and its association with renal abnormalities in two patients.
