Abstract:
The coexistence of pituitary adenoma (PA) and meningioma in the same patient is rare, after excluding radiotherapy-induced meningiomas. Most of the literature on their coexistence describes meningiomas located in the close vicinity to PA, that is, in the sellar/parasellar region. We describe a case of a 65-year-old lady with a nonfunctioning PA and an associated frontal convexity meningioma with frontal sinus invasion. The imaging was nonspecific for the meningioma, and its association with concomitant PA has not been reported before.
Insights
A rare case of pituitary adenoma (PA) coexisting with a frontal convexity meningioma is presented. This unusual association, with atypical meningioma location and frontal sinus invasion, has not been previously reported in medical literature.
Area of Science:
- Neuro-oncology
- Endocrinology
- Neurosurgery
Background:
- Pituitary adenomas (PA) and meningiomas are common intracranial tumors.
- Coexistence of PA and meningioma is rare, typically occurring in the sellar/parasellar region.
- Radiotherapy-induced meningiomas are excluded in this context.
Observation:
- A 65-year-old female presented with a nonfunctioning pituitary adenoma.
- She also had an associated frontal convexity meningioma with frontal sinus invasion.
- Initial imaging findings for the meningioma were nonspecific.
Findings:
- This case represents the first reported instance of a nonfunctioning pituitary adenoma coexisting with a frontal convexity meningioma.
- The meningioma's location and invasion pattern were atypical.
- The association between these two distinct tumor types in this specific configuration is novel.
Implications:
- Highlights the importance of considering rare tumor associations in clinical diagnosis.
- May prompt further research into potential shared etiologies or risk factors for pituitary adenoma and meningioma.
- Challenges current understanding of tumor localization patterns for coexisting pituitary adenomas and meningiomas.

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,...

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...
