Summary
Aneurysmal bone cysts (ABC) are rare primary bone tumors, typically affecting young individuals. This case highlights a locally aggressive ABC in an adult patient affecting the ulna bone.
Area of Science:
- Orthopedics
- Oncology
- Pathology
Background:
- Aneurysmal bone cysts (ABC) represent 1-4% of primary bone tumors.
- These benign lesions predominantly affect individuals aged 10-20 years and are uncommon after 50.
- Despite their benign nature, ABCs can exhibit local aggressiveness and significant growth.
Observation:
- The study reports a case of an aneurysmal bone cyst (ABC).
- The patient presented with an ABC located in the ulna.
- This specific case involved a locally aggressive lesion of considerable size.
Findings:
- The aneurysmal bone cyst (ABC) in this patient demonstrated significant local aggression.
- The ulna bone was affected by the tumor.
- The benign tumor attained a large size, impacting the ulna.
Implications:
- This case underscores that aneurysmal bone cysts (ABCs), though typically benign, can present aggressively even in older age groups.
- The significant size and aggressive nature of the ulna ABC highlight the need for careful monitoring and management.
- Understanding the variable presentation of ABCs is crucial for accurate diagnosis and treatment planning in orthopedic oncology.

01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

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...

01:09Spongy Bone
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

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...
