Summary
A rare aneurysmal bone cyst (ABC) in the pubic ramus was successfully treated with surgical excision in a young male. This case highlights the importance of histopathology for diagnosing this rare bone lesion.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Aneurysmal bone cysts (ABC) are expansile, lytic, fluid-filled bone lesions.
- ABC typically occur in the metaphysis of long bones.
- ABC of the pubic ramus is an exceptionally rare presentation.
Observation:
- A 21-year-old male presented with a progressive right inguinal swelling.
- Radiological imaging revealed a lytic, expansile lesion of the superior pubic ramus.
- Contrast-enhanced CT demonstrated multiloculated cystic cavities.
Findings:
- Histopathology confirmed the diagnosis of aneurysmal bone cyst (ABC).
- The patient underwent surgical excision of the pubic ramus lesion via an anterior approach.
- No recurrence was observed two years post-surgery.
Implications:
- Surgical excision is a viable treatment for large or strategically located pubic ramus ABCs.
- Differential diagnoses must be considered for pubic ramus lesions.
- Histopathological confirmation is crucial for accurate diagnosis and treatment planning.

01:09Bones of the Upper Limb: Radius
10.8K
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.

01:19Bones of the Upper Limb: Humerus
13.4K
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...

01:16Bones of the Lower Limb: Femur and Patella
9.1K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

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...

01:26Bone Markings
8.7K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:09Spongy Bone
10.1K
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...
