A thorough knowledge of the normal range of variation of anatomy and topography of the cochlea is necessary for optimal reproduction of this structure and correct interpretation of the radiographs. Radiographic identification of incomplete cochlear coils is essential in the diagnosis of congenital malformations such as Modini's deformity. Furthermore, a diagnosis of otosclerosis/otospongiosis has to be based on recognition of changes in the otic capsule. The size and shape of the human cochlea and the normal ranges of variation of its dimensions were evaluated in 95 plastic casts, prepared from temporal bone specimens. The normal range of variation is fairly small, and is not age-dependent. Obvious digression from this range, associated with pertinent clinical symptoms, indicates an abnormality.

The case of a 4-year-old patient with a diaphragmatic haemangioma is reported. There were no symptoms and the only clinical finding was prominent subcutaneous vessels on the abdominal wall. The lesion was revealed by imaging and was excised. The findings and the differential diagnosis are discussed.

The case of a 3-month-old boy with a hepatic infantile hemangioendothelioma is reported. There was no previous history of disease and no symptoms, only an incidentally found abdominal mass. The case is presented as an example of establishing the diagnosis, deciding upon the treatment, and performing the follow-up using only non-invasive imaging techniques.

Pulmonary vein varix is a rare benign abnormality, either congenital or acquired, usually presented without symptoms. It is most frequently discovered by chance on a chest radiograph, whereas computed tomography defines the special characteristics of the lesion. Angiography is considered the method of choice for final diagnosis. The authors present the first case of a patient with pulmonary vein varix accompanied by interatrial communication.
