The characteristic radiologi...

This study assesses function after limb sparing bone tumour resections of the proximal humerus. Twenty-seven patients had an intraarticular resection with reconstruction using an anatomic prosthesis-bone graft composite with average clinical follow-up of 63 years (range: 13-15.8 years). Pain relief was achieved for 22 shoulders (81%); 19 of 25 patients responding (76%) were satisfied. Active el...

NF2 gene – Chr 22 VHL (Von Hippel Lindau) disease – Chr 3p Ionizing radiation Criteria for radiation induced temporal bone tumours by LUSTIG is as follows : 1. • The second neoplasm must develop in the irradiated field. 2. • A latent period of at least several years must elapse between radiation exposure and the development of a second primary. 3. • The previous condition must show histological...

Chondroblastoma is a mostly benign bone neoplasm that typically affects the second decade of life and exhibits a lytic lesion in the epiphysis of long bones. We report an extreme case of massive, destructive chondroblastoma of the proximal humerus in a 9-year-old girl. It was difficult to differentiate using imaging information the lesion from malignant bone tumors such as osteosarcoma. Histopa...

Osteomas are the slow growing benign tumours of the lamellar bones. They are the most common benign neoplasm of nose and paranasal sinuses.

Approximately 2% of GCTs occur in the craniofacial skeleton with a predilection for the ethmoid, sphenoid, and temporal bones. The skull base location is unique and not commonly describe...
