“…The radiological features are similar to those of the extracranial counterpart (i.e. sharp margins, a uni- or multicystic appearance with fluid-fluid levels, hemorrhagic changes and contrast enhancement limited to the solid component) [6, 7, 8]. Erosion of cortical bone, a feature of the present lesion, is less common [9].…”

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.

“…ABCs also occur secondary to other bone tumors such as chondroblastomas, giant cell tumor, chondromyxoid fibroma, non-ossifying fibromas, or fibrous dysplasia [6,7]. These secondary ABCs account for nearly 30 % of all ABCs, and they are not considered a neoplasm because no known translocation or genetic aberrancy is present [7].…”

Aneurysmal bone cysts (ABCs) are benign bone lesions arising predominantly in the pediatric population that can cause local pain, swelling, and pathologic fracture. Primary lesions, which constitute roughly two thirds of all ABCs, are thought to be neoplastic in nature, with one third of ABCs arising secondary to other tumors. Diagnosis is made with various imaging modalities, which exhibit characteristic features such as Bfluid-fluid levels,^although biopsy is critical, as telangiectatic osteosarcoma cannot be excluded based on imaging alone. Currently, the standard of care and most widely employed treatment is intralesional curettage. However, tumor recurrence with curettage alone is common and has driven some to propose a multitude of adjuvants with varying efficacy and risk profiles. Historically, therapies such as en bloc resection or radiation therapy were utilized as an alternative to decrease the recurrence rate, but these therapies imposed high morbidity. As a result, modern techniques now seek to simultaneously reduce morbidity and recurrence, the pursuit of which has produced preliminary study into minimally invasive percutaneous treatments and medical management.

“…ABC may present as a primary osteolytic lesion (65%), including the solid variant, 50 or as secondary changes in another lesion (35%). 51,52 No case of malignant transformation of a primary ABC has ever been reported. 52 Management includes surgical curettage with or without bone grafting, cementing of the cavity, reconstructive surgery, embolization and, more recently, sclerotherapy.…”

Interventional radiology technique is now well established and widely used in the adult population. Through minimally invasive procedures, it increasingly replaces surgical interventions that involve higher percentages of invasiveness and, consequently, of morbidity and mortality. For these advantageous reasons, interventional radiology in recent years has spread to the paediatric age as well. The aim of this study was to review the literature on the development, use and perspectives of these procedures in the paediatric musculoskeletal field. Several topics are covered: osteomuscle neoplastic malignant and benign pathologies treated with invasive diagnostic and/or therapeutic procedures such as radiofrequency ablation in the osteoid osteoma; invasive and non-invasive procedures in vascular malformations; treatment of aneurysmal bone cysts; and role of interventional radiology in paediatric inflammatory and rheumatic inflammations. The positive results that have been generated with interventional radiology procedures in the paediatric field highly encourage both the development of new ad hoc materials, obviously adapted to young patients, as well as the improvement of such techniques, in consideration of the fact that childrens' pathologies do not always correspond to those of adults. In conclusion, as these interventional procedures have proven to be less invasive, with lower morbidity and mortality rates as well, they are becoming a viable and valid alternative to surgery in the paediatric population. MUSCULOSKELETAL MALIGNANT TUMOURSOsteosarcoma, Ewing sarcoma and rhabdomyosarcoma are the most common musculoskeletal tumours of childhood and adolescence.
