“…CT scan and MRI findings are nonspecific [11, 12]. Unlike in the present lesion, contrast enhancement is often marked [12]. On MRI, a minority of cases of EG may show a peripheral rim of decreased intensity similar to that seen in the lesion described here [11].…”

We describe the case of a 2-year-old male patient with an aneurysmal bone cyst (ABC) of the occiput secondary to unifocal eosinophilic granuloma (EG). The lesion presented as a painless mass of the scalp which had grown rapidly over the 2 weeks prior to admission. Radiologically, the lesion was osteolytic and multicystic with fluid-fluid levels. On histology, the cyst wall contained hemosiderin-laden histiocytes, spindle cells, multinucleated giant cells, Langerhans’ cells and eosinophils. Surgical treatment consisted of en bloc resection. Fourteen months after surgery, the patient was well with no local recurrence. Association between EG and ABC is rare. To our knowledge, this is the first case involving the skull.

The chapter begins with the discussion of spondylolysis and spondylolisthesis, including a section describing various methods for imaging these conditions. Intervertebral disc disease follows, with discussion of intervertebral calcifi cation and disc prolapse. Spinal trauma is addressed, along with infl ammatory and neoplastic destructive vertebral lesions. The last section of the chapter covers salient features of tumors that occur in the spine, including osteoid osteoma, osteoblastoma, aneurysmal bone cyst, Langerhans cell histiocytosis, and osteochondroma.The pediatric spine is affected by a variety of processes that are unique to children or that manifest in children in unusual ways. Spondylolysis represents a response to chronic stress injury and may lead to spondylolisthesis, wherein one vertebra slips forward on the subjacent vertebra. Spine fractures in young children differ greatly from those in adults and are especially common in the upper cervical spine. Discitis, an uncommon idiopathic infl ammatory process, is essentially limited to children, whereas disc herniation and spine infection in children resemble these processes in adults. Several bone tumors, such as osteoid osteoma/osteoblastoma, Langerhans cell histiocytosis, and osteochondroma have unique appearances in the spine. (Infl ammatory,

This chapter fi rst discusses general principles of tumor imaging, including both characteristics of benign and malignant tumors and utility of different imaging modalities. It then enters an in-depth discussion of benign tumors and tumor-like lesions, addressing cystic, cartilaginous, osseous, fi bro-osseous, and vascular lesions, along with Langerhans cell histiocytosis. It concludes with a review of osteosarcoma and Ewing sarcoma, the more common malignant tumors, as well as chondrosarcoma, lymphoma, malignant fi brous histiocytoma, and metastatic disease.
