Atlanto-Axial Dislocation with Odontoid Process Fracture Associated with "Cruciate Paralysis"

Cruciate paralysis, an unusual clinical entity, is "frequently undiagnosed or misunderstood", and can simulate the acute cervical central-cord injury syndrome. This rare injury pattern is characterized by weakness of upper extremities with little or no compromise of lower limb function following trauma to the superior cervical cord. The pattern of injury and clinical findings support selective damage to the corticospinal tract or upper motor neurons subserving upper limb function with the pyramidal decussation. Authors experience a case of curciate paralysis due to type 2 odontoid fracture and atlas dislocation.

Primary Chondroid chordoma Arising from the Base of the Petrous Temporal Bone: Case Report

The authors report an unusual case of a primary chondroid chordoma arising from the base of the petrous temporal bone. A 43-year-old female presented with left sided facial weakness and left sided jugular foramen syndrome. The CT findings of a tumor arising from the base of left petrous temporal bone and it involved left cerebello-pontine angle, and extended through left jugular foramen to parapharyngeal space. The clinical and histopathologic differences between classical(typical) chordoma and its variant are highlighted. The rarity of primary chordomas at this site is stressed.
