Acute hematogenous osteomyelitis of the odontoid process in a child with torticollis.

Acute vertebral osteomyelitis is rare in the pediatric population. Its presentation may be subtle and without constitutional manifestations. We present a case of osteomyelitis of the odontoid process.

Unusual manifestations of astroblastoma: a radiologic-pathologic analysis.

Astroblastoma is a very rare primary glial tumor occurring in children and young adults that is almost exclusively supratentorial in location. We report an extremely unusual presentation of a densely calcified posterior fossa astroblastoma with disseminated spinal and supratentorial metastasis. The mass exhibited neoplastic bone formation, which has not been reported, although calcifications are commonly seen in astroblastomas.

Intradural capillary hemangioma of the cauda equina.

Hemangiomas, which are usually found in the skin, are extremely rare in an intradural location. An unusual case of capillary hemangioma intimate to the cauda equina is discussed. This entity has not previously been reported in the pediatric or adolescent population to the best of our knowledge, although it has been reported in adults.
