Summary
A rare Masson's tumor, a benign vascular neoplasm, caused an ulnar artery aneurysm in a 30-year-old woman. Surgical resection and vascular reconstruction successfully treated the condition, resolving her symptoms.
Area of Science:
- Vascular Surgery
- Pathology
- Medical Imaging
Background:
- Intravascular papillary endothelial hyperplasia (Masson's tumor) is a rare benign vascular neoplasm.
- Arterial aneurysms can present with mass effect and neurological symptoms.
- Ulnar artery aneurysms are uncommon, particularly in healthy young individuals.
Observation:
- A 30-year-old woman presented with a pulsatile forearm mass and digital numbness.
- Duplex scan identified an ulnar artery aneurysm with an intramural thrombus.
Findings:
- Histopathology confirmed Masson's tumor as the cause of the ulnar artery aneurysm.
- This is the first reported case of Masson's tumor in the ulnar artery.
Implications:
- Local resection and vascular reconstruction offer a curative treatment for ulnar artery aneurysms caused by Masson's tumor.
- Prompt diagnosis and surgical intervention can resolve associated neurologic deficits.

Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
Bones 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...
Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

Bones 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...

Bones 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...
