Abstract
BACKGROUND

Meningiomas represent the most common primary intracranial tumor in adults. The majority of meningiomas are indolent, benign, and sporadic in nature. The incidence of meningiomas is directly proportional to the age, peaking around 65 years. The presenting symptomatology of intracranial meningiomas is mainly dependent on their anatomical location, as with the majority of brain tumors. Surgical resection and radiation therapy remain the treatment modality for meningiomas of all grades.

CASE SUMMARY

We present a case describing a 78-year-old female who came in following a ground level fall. The primary assessment was notable for a history of similar recurrent falls and subtle left-sided peripheral visual field loss. Further neurological examination was otherwise largely unremarkable. A computed tomography scan of the head revealed a large extra-axial mass located along the posterior aspect of the falx. Follow-up magnetic resonance imaging confirmed a lesion measuring around 6.6 cm × 4.2 cm × 5.5 cm. A partial surgical resection of the right-sided portion of the lesion was performed. Complete resection was limited by insufficient visualization and challenges with hemostatic control of the left parafalcine region. Further histopathological analysis confirmed a fibrous meningioma with focal necrosis, consistent with World Health Organization Grade 2 classification. She was subsequently scheduled for outpatient follow-up to assess the residual tumor management.

CONCLUSION

This case highlights the importance of maintaining a high index of suspicion for intracranial pathology in elderly patients with nonspecific presentation.

Core Tip: This case report presents an unusual clinical scenario describing a 78-year-old female who was admitted after a ground-level fall. Neuroimaging unexpectedly revealed a large intracranial mass, measuring over 6 cm at its greatest and situated in the posterior falx. It was associated with extensive vasogenic edema and mass effect. This imaging finding was remarkable given the minimal symptomology of the patient's presentation with no significant neurological deficits. Only a subtotal resection was feasible in our case. Histopathological analysis confirmed the diagnosis of fibrous meningioma with areas of focal necrosis. Other info: (1) Informed consent was obtained; (2) Does not apply to case reports; (3) Manuscript has been reviewed multiple times; and (4) Fibrinous meningioma represents a rare and under-characterized histological variant ofmeningioma, with distinct pathological features such as extensive fibrin deposition and reduced tumor cellularity. This case does not exemplify a new treatment or new mechanism research. The case has an educational value regarding rare occurrence of subtype of meningiomas.
