High-grade spheno-orbital meningioma in patients with systemic lupus erythematosus: Two case reports and literature review.

Background Spheno-orbital meningiomas (SOMs) are often benign. The association of meningioma and systemic lupus erythematosus (SLE) is rarely discussed in the literature. Here, we report two patients with high-grade, SOMs with a prolonged history of SLE and review the literature. Case description The first case is a 52-year-old female patient with a 15-year history of SLE diagnosis who was referred to our center with a 1-year history of proptosis and excessive tearing of the left eye. This patient was operated for the left SOM with histopathological diagnosis of the World Health Organization (WHO) Grade III rhabdoid meningioma. The second case is a 36-year-old female patient with a 12-year history of SLE diagnosis who presented to our clinic with a 5-year-history of progressive right eye proptosis and occasional headaches. She was operated for the right SOM with histopathological diagnosis of the WHO Grade II chordoid meningioma. Conclusion Rhabdoid and chordoid SOMs are uncommon and no previous report discussed their occurrence in patients with SLE. The association of high-grade meningiomas and SLE deserves further exploration.
