Abstract:
Juvenile psammomatoid ossifying fibroma (JPOF) is an uncommon benign fibro-osseous lesion predominantly arising in the paranasal sinuses and orbits of children and young adults. We report a case of JPOF involving the paranasal sinuses and orbit in a 15-year-old boy that presented due to progressive proptosis and downward displacement of the left eye. The lesion, first described as fibrous dysplasia (FD), was totally removed surgically, and then proved to be a JPOF, by histopathology. We discuss its differential diagnosis with other fibro-osseous lesions, histopathological features, and treatment options.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
