Summary
A sellar spine, an unusual bony spur in the pituitary fossa, was incidentally found. This rare anatomical variant can cause headaches or hormonal issues.
Area of Science:
- Neurosurgery
- Radiology
- Endocrinology
Background:
- A sellar spine is a rare midline osseous spur arising from the dorsum sellae and projecting into the pituitary fossa.
- It is often an incidental finding on imaging studies.
- Potential clinical manifestations include optic chiasm compression and hormonal disturbances.
Purpose of the Study:
- To report a case of incidentally detected sellar spine.
- To highlight the clinical presentation of sudden onset headaches associated with this anatomical variant.
Main Methods:
- Case report presentation.
- Review of relevant medical literature.
Main Results:
- Incidental detection of a sellar spine during imaging for headaches.
- No immediate complications or symptoms directly attributed to the sellar spine were noted at the time of presentation.
Conclusions:
- Sellar spines are rare anatomical variations that can be incidentally discovered.
- While often asymptomatic, their potential to cause neurological or endocrine symptoms warrants consideration in the differential diagnosis.

01:22Sutures of the Skull
6.4K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:16Vertebral Column: Regions and Curvature
3.5K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

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...

01:09Overview of the Axial Skeleton
5.1K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

01:09Spongy Bone
4.2K
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...

01:27Compact Bone
11.3K
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...
