Fronto-orbitonasal intradiploic meningioma in a child

Abstract:
Intradiploic meningioma, which may be classified as a subgroup of intraosseous meningioma, is a rarely encountered disorder. To date, less than 10 cases have been reported. Here, we report a case of fronto-orbitonasal intradiploic meningioma. A 12-year-old female with exophthalmos and diplopia was operated on for a cranial intradiploic mass lesion. Histopathological evaluation of the specimen confirmed the diagnosis of intradiploic psammomatous meningioma. Her exophthalmos did not change, but the diplopia disappeared. This case is unique in that it is an extensive case of intradiploic meningioma of the orbital roof and frontal base in a child. Intradiploic meningiomas generally are of psammomatous type. Especially tumors adjacent to the orbita cause exophthalmos; cases located on the other side of the calvarium may not cause any symptom or sign other than headache or sometimes a mass on the scalp. Treatment, as with meningiomas located in the intracranial cavity, is total resection of the lesion.
Insights
This report details a rare fronto-orbitonasal intradiploic meningioma in a child. Surgical resection resolved diplopia, highlighting treatment for this uncommon cranial tumor.
Area of Science:
- Neurosurgery
- Pediatric Oncology
- Pathology
Background:
- Intradiploic meningiomas are rare intraosseous tumors, often psammomatous, with fewer than 10 reported cases.
- These tumors can present with varied symptoms depending on location, including exophthalmos and headache.
Observation:
- A 12-year-old female presented with exophthalmos and diplopia due to a cranial intradiploic mass.
- The lesion was located in the fronto-orbitonasal region, affecting the orbital roof and frontal base.
Findings:
- Histopathological evaluation confirmed the diagnosis of intradiploic psammomatous meningioma.
- Surgical resection led to the disappearance of diplopia, although exophthalmos persisted.
Implications:
- This case represents an extensive intradiploic meningioma in a pediatric patient, offering insights into its presentation and management.
- Total resection is the recommended treatment for intradiploic meningiomas, similar to intracranial meningiomas.

01:27Cranial Bones: Lateral View
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...

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