Summary
A rare solid variant of aneurysmal bone cyst (ABC) was found in a woman's rib. Surgical resection confirmed the diagnosis of this unusual bone lesion.
Area of Science:
- Orthopedic Oncology
- Thoracic Surgery
- Pathology
Background:
- Aneurysmal bone cysts (ABC) are rare, benign bone tumors typically affecting long bones and the spine.
- Solid variants of ABC are exceptionally uncommon, presenting diagnostic challenges.
Observation:
- A 29-year-old female presented with an abnormal chest X-ray finding.
- Imaging revealed a lesion on the right 4th rib, confirmed by CT and bone scintigraphy.
- The lesion showed increased uptake on bone scintigram, indicating high metabolic activity.
Findings:
- Surgical resection of the right 4th rib, including surrounding tissues, was performed.
- Pathological examination post-surgery definitively diagnosed a solid variant of aneurysmal bone cyst.
- This case highlights the occurrence of solid variant ABC in the thoracic skeleton.
Implications:
- This case expands the known anatomical locations for solid variant ABC.
- Accurate diagnosis and surgical management are crucial for rare bone tumors like solid variant ABC.
- Further research into the pathogenesis and optimal treatment of solid variant ABC is warranted.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:17Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
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 adults, it...
