Abstract
Chordoid meningioma is an uncommon histopathological type of meningioma, frequently associated with Castleman's syndrome. Histologically, chordoid meningiomas are similar to chordomas. Because of their high proliferative index, they present aggressive biological behavior and high risk of postoperative recurrence. We report a case of choroid meningioma in adult patient without Castleman's syndrome manifestation. As its chordoid features is related with a rapid recurrence after incomplete removal, meticulous histopathological examination is crucial for the adequate postoperative treatment plan.
Highlights
Meningioma is the most common benign intracranial tumor, representing 13-36% of all primary central nervous system neoplasms
The term chordoid meningioma was initially presented by Kepes, et al [7] who defined it as having a chordoma-like histologic appearance with a clustering of tumor cells
We report a 71-years-old patient with chordoid meningioma in parasagittal region infiltrating the superior sagittal sinus and motor cortex of the left hemisphere
Summary
Meningioma is the most common benign intracranial tumor, representing 13-36% of all primary central nervous system neoplasms. Starting form 2007 all meningiomas with cortical invasion became considered as grade II [3]. This increased the rate of these meningiomas from 5% to 20-35% [3]. We report a 71-years-old patient with chordoid meningioma in parasagittal region infiltrating the superior sagittal sinus and motor cortex of the left hemisphere. Cranial magnetic resonance imaging (MRI) revealed a 3 × 4 × 4 cm mass in the left occipital region with superior sagittal sinus infiltration (Figure 1A and Figure 1B). Control magnetic resonance imaging carried out one month after surgery confirmed tumor remnants within the superior sagittal sinus cavity (Figure 1C and Figure 1D).
