ABSTRACT
We report the case of a large osteoblastoma arising in the frontal bone of a 20-year-old female. The lesion was first noted after a fall, and grew steadily in size following further head injury during pregnancy. Initial plain radiography demonstrated an area of radiolucency, with subsequent cross-sectional imaging revealing the extent of the lesion. Following successful surgical resection, histological features were suggestive of an aggressive osteoblastoma with aneurysmal bone cyst-like changes. We consider the influence of pregnancy and trauma on osteoblastoma behavior.

Osteoblastoma is a rare, solitary benign tumor that is usually situated in axial skeleton mainly in vertebra. It is rarely seen in ethmoid and frontal sinuses. A 40-year-old man who had osteoblastoma originated from frontal and ethmoidal sinuses that extends up to frontal lobe and gave rise to personality disorders by compressing the frontal lobe, and caused superior gaze palsy by compressing the superior rectus muscle. We present this rare case with clinical, radiological and histopathological findings.

Back pain in the young athlete is a common finding. There are many different problems that can cause back pain in active children. It is important for the treating physician to obtain a thorough history and physical examination to help in establishing the underlying cause for the discomfort. Appropriate imaging can be determined by these findings and further help to define the pathology. Depending upon the specific pathology, appropriate treatment may help the patient to safely return to the activities that they enjoy.

A 26-year-old man with a chronic subgaleal hematoma containing calcific elements subsequently developed an aggressive osteoblastoma within the lesion. It is presumed that the osseous elements associated with the chronic process underwent neoplastic alteration. Such a lesion should be suspected in an individual with a long-standing subgaleal hematoma who reports changes occurring with respect to either size of the lesion or the development of tenderness.
