[Crowned Dens syndrome: calcification of the transverse ligament of the atlas].
Axial skeleton affection due to chondrocalcinosis has been associated to calcium deposits in the intervertebral disc, the yellow ligament, the fact joints and even the sacroiliac joints. Calcification of the transverse ligament of the atlas (Figs. 1–3) is an infrequent manifestation and has been denominated the Crown Dens syndrome. It mostly constitutes an asymptomatic clinical picture but may ...
متن کاملA nodular calcification of the alar ligament simulating a fracture in the craniovertebral junction.
We report a case of an incidental nodular calcification of the alar ligament simulating a fracture in the craniovertebral junction of a previously healthy 24-year-old man. Three-dimensional CT and MR imaging revealed a 7.2 x 7.6 x 4.0 mm nodular calcification in the right alar ligament with normal adjacent bony structures. Serial cervical dynamic radiographs and open-mouth views showed that the...

متن کاملMorphology of the transverse ligament of the atlas and the alar ligaments in the silver fox (Vulpes vulpes var)
BACKGROUND Recent new anatomical and histological features of craniocervical junction in dogs and cats were described providing evidence of differences between the carnivore species. No information on these structures in foxes exists. RESULTS Two parts of the alar ligaments were found. A longer one aroused from dens of axis to the internal (medial) surface of the occipital condyles and was ca...
متن کاملCalcification of the transverse ligament of the atlas in chondrocalcinosis: computed tomography study.
OBJECTIVE To seek an association between articular chondrocalcinosis (AC) and calcification of the transverse ligament of the atlas (TLA), and to evaluate the frequency and the main computed tomography appearances of such calcification. METHODS Axial computed tomography slices of the cervico-occipital hinge were performed routinely in 21 patients with AC (three men, 18 women; mean age 79 year...
