Summary
This review details the anatomy of the supraspinous fossa and its common pathologies. Understanding imaging findings of supraspinous fossa lesions aids radiologists in accurate diagnosis.
Area of Science:
- Radiology
- Anatomy
- Pathology
Background:
- The supraspinous fossa is a key periscapular region containing the supraspinatus muscle and suprascapular nerve.
- Pathologies can affect the fossa's contents, osseous boundaries, or superficial soft tissues.
Purpose of the Study:
- To provide a comprehensive pictorial review of the supraspinous fossa's detailed anatomy.
- To illustrate a wide spectrum of pathologies affecting the supraspinous fossa.
- To enhance radiologists' awareness of imaging findings for accurate diagnosis.
Main Methods:
- Detailed anatomical description of the supraspinous fossa.
- Compilation of imaging findings for various supraspinous fossa pathologies.
- Pictorial review format.
Main Results:
- Detailed anatomical depiction of the supraspinous fossa.
- Imaging characteristics of diverse lesions including paralabral cysts, muscle edema/atrophy, malignancies, myositis ossificans, fibromatosis, and nerve sheath tumors are presented.
Conclusions:
- Familiarity with the anatomical structures and imaging features of supraspinous fossa pathologies is crucial for radiologists.
- This knowledge aids in avoiding misinterpretation and facilitates timely and accurate diagnosis of supraspinous fossa conditions.

01:27Muscles of the Vertebral Column
1.1K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

01:30General Structure of a Vertebra
2.6K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

01:14Cranial Bones: Superior and Posterior View
1.9K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:31Muscles that Move the Arm
1.6K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:23Muscles of the Shoulder
3.6K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:16Bones of the Lower Limb: Femur and Patella
2.2K
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...
