Abstract:
Chondroblastoma is a rare benign tumor that typically arises in the epiphyses or apophyses of long bones in patients with immature skeletal structures. Occasionally, it presents in atypical sites such as the bones of the foot and craniofacial region. This report details the case of an 18-year-old female who experienced neck pain and was found to have a lesion in the left jugular foramen. Imaging revealed typical lytic and expansive bone destruction with invasion into the adjacent internal jugular vein. Initially misdiagnosed as a glomus jugulare tumor, definitive diagnosis of chondroblastoma was established postoperatively via histopathology. This case underscores the diagnostic challenges posed by chondroblastomas at atypical sites. Through detailed imaging, histopathological analysis, and literature review, this study aims to enhance the awareness of clinicians and radiologists regarding chondroblastoma and provides insights and references for the diagnosis and management of similar cases in the future.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

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...
