Summary
Giant pericranial sinus, a rare cause of extensive cranial vault defects, presents diagnostic challenges. Surgical intervention and follow-up confirmed a favorable outcome for this rare condition.
Area of Science:
- Neurosurgery
- Radiology
- Pathology
Background:
- Giant non-traumatic cranial vault defects are rare and poorly understood.
- Literature review revealed only 4 documented cases of giant pericranial sinus with extensive cranial defects.
Purpose of the Study:
- To present a rare case of a large cranial vault defect with non-traumatic and non-iatrogenic bone loss.
- To propose a treatment strategy for this rare pathology.
Main Methods:
- Comprehensive patient examination including CT angiography.
- Surgical intervention involving bone resection, biopsy, and titanium plate reconstruction.
- Postoperative imaging (CT, angiography, sinusography) and follow-up exceeding 10 months.
Main Results:
- Diagnosis of giant dominant-type true pericranial sinus established.
- Uneventful postoperative period with a favorable outcome after 10 months of follow-up.
Conclusions:
- Giant pericranial sinus is a rare but treatable cause of extensive cranial vault defects.
- Multimodal diagnostic and surgical approaches are crucial for successful management.

01:14Cranial Bones: Superior and Posterior View
2.0K
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,...

01:27Cranial Bones: Lateral View
2.0K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:08Overview of the Skull
4.3K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:19Cranial and Spinal Meninges
1.2K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:18Anatomy of the Brain: Ventricles
3.0K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

01:22Sutures of the Skull
6.2K
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...
