11-months-old male showed signs of tumefaction in the left frontotemporal region. An ultrasound showed a solid noncalcified neoformation, and a brain CAT scan showed a small solid lesion resulting in erosion of the cranial theca both in the external and internal table. Based on clinical status and tomodensitometric appearance, the diagnosis of suspected eosinophilic granuloma or hystiocytosis X was made, and a surgical curettage of the craniolacunia was recommended in order to comfirm the diagnosis.

1.5-year-old male suffered from eye swelling. His MRI revealed expansive lesion of left lateral orbital wall origin, with compression on the lateral rectus muscle. Later he was hospitalized due to fever and vomiting in left orbital lesion, suspecting a metastatic neuroblastoma. His eye examination revealed exophthalmus of the eye with exophoria and light dysfunction of the lateral rectus. His biopsies were indicative of stroma-poor neuroblastoma.
