Imaging of the absent cervical pedicle.

The absent cervical pedicle is an interesting congenital anomaly which has been described in several previous case reports. Of primary importance is its recognition to avoid confusion with more clinically significant abnormalities such as fracture or an enlarged neural foramen. Although many cases can be diagnosed from the plain radiographic findings alone, it is occasionally necessary to employ another imaging modality for more definitive evaluation. We describe two cases of absent cervical pedicle imaged with computed tomography and magnetic resonance imaging.

The calcaneus: normal and abnormal.

The calcaneus is the largest tarsal bone. Many congenital and acquired disorders affect the bone. Primary disorders arise in the calcaneus itself, whereas secondary disorders arising in the neighboring soft tissues extend into and affect the calcaneus indirectly. Among the primary lesions, congenital, traumatic, infectious, hematologic, neoplastic, and other miscellaneous disorders constitute the majority, whereas various arthritides and soft-tissue neoplasms that arise adjacent to the bone constitute the important secondary calcaneal disorders. Radiographic features of many disorders of the calcaneus are disease-specific and thus diagnostic. This article describes a wide spectrum of calcaneal disorders and illustrates their salient radiographic features. This knowledge should facilitate radiographic diagnosis of various calcaneal disorders encountered in clinical practice.
