Insights

An ossified meningioma, a rare intracranial tumor, was identified in a young woman presenting with chronic headaches. Surgical removal confirmed the diagnosis, with no recurrence after two years.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Meningiomas are common primary intracranial tumors, but ossified variants are exceptionally rare.
  • Differentiating ossified meningiomas from other calcified intracranial lesions can be challenging based on imaging alone.

Observation:

  • A 28-year-old female presented with a four-year history of headaches.
  • Neuroimaging revealed an extra-axial calcified mass in the left parieto-occipital region.
  • Differential diagnoses included osteoblastoma, calcifying pseudotumor, hyperostosis, and ossifying fibroma.

Findings:

  • Surgical excision of the calcified lesion was performed.
  • Histopathological examination confirmed the diagnosis of ossified meningioma.
  • The patient remained asymptomatic with no signs of tumor recurrence at the 2-year follow-up.

Implications:

  • This case highlights the importance of considering ossified meningioma in the differential diagnosis of calcified intracranial masses.
  • Complete surgical excision appears to be an effective treatment, leading to favorable long-term outcomes.
  • Further research into the specific characteristics and behavior of ossified meningiomas is warranted.

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

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,...

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

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...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

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...

Sutures of the Skull01:22

Sutures of the Skull

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...

Overview of the Skull01:08

Overview of the Skull

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...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...
