“…7,8 The provisional diagnosis of orbital proptosis includes thyroid disease related proptosis, idiopathic orbital Inflammation, metastasis, orbital lymphoma, and meningoencefalocele. 9 This patient had normal thyroid function tests; therefore, thyroid eye disease can be ruled out in this case. Moreover, primary orbital lymphomas can be ruled out by the histopathological results.…”

“…Unlike meningioma, meningoencephalocele presents as a combination of fluid-filled cyst and parenchyma with no contrast enhancement and shows a continuity between brain parenchyma and herniated meningoencephalocele on MRI images. 9 The patient was diagnosed with Spheno-orbital meningioma through specific findings in the MRI images and specimen biopsy of the lesion which specifically stained positive for EMA. The patient underwent gross tumor reduction by neurosurgical and orbital intervention.…”

Spheno-orbital meningiomas are benign tumors. They arise intracranially from the sphenoid ridge arachnoid villi cap cells, extending into the orbit. Herein, the authors report a case of a 50-year-old female who presented to Ophthalmology department with a complaint of right eye proptosis. Magnetic resonance imaging and biopsy showed a right sphenoid-orbital meningioma. The tumor was excised and the patient symptomatically improved. Patient had gross tumor reduction for right sphenoidal orbital extra-axial brain tumor with hyperostosis of the lateral wall of the orbit and sphenoidal ridge.

“…[10][11][12] Although the original paper that proposed the classification system for PEM considered PIM a different entity from PEM based on the sex predilection, age distribution, and tendency for malignancy, some considered PIM as a subset of PEM based on the anatomical considerations. 3,6,8,[14][15][16][17] By definition, PIMs arise from the bone, particularly the calvaria, and the sphenoid bone and frontal bone are the most common locations, followed by the parietal bone, temporal bone, orbit, and other regions. 3,11,12 There have been a few reports in recent decades of intraosseous meningiomas arising from the vertebrae where meningiomas had metastasized to the vertebrae from their intracranial origin; therefore, these tumors cannot be categorized into "primary" intraosseous meningiomas.…”

“…The majority of PIMs are of osteoblastic origin and have the typical findings of hyperostosis; however, some have radiographic evidence of osteolytic changes. 3 , 6 , 12 , 14 , 17 The differential diagnosis of osteolytic lesions in vertebrae includes metastasis, primary bone tumors, multiple myeloma, Langerhans cell histiocytosis, or osteomyelitis. Biopsy is indicated to differentiate between the osteolytic lesions because most primary bone tumors necessitate wide excisions to achieve better clinical outcomes.…”

BACKGROUND Primary intraosseous meningiomas (PIMs) are rare, and PIMs of the vertebrae have not yet been reported. The authors report a case of primary meningioma arising from the vertebrae. OBSERVATIONS A 49-year-old man presented with lower back pain and numbness in both lower extremities. Lumbar spine magnetic resonance imaging revealed an L2 pathological fracture with epidural and paraspinal invasion. The patient had undergone a first palliative decompression and fixation surgery, and the diagnosis turned out to be a World Health Organization grade III anaplastic meningioma based on histopathology. The tumor had progressed after first operation and radiation therapy, and the patient was referred to the authors’ institute for excision. The patient had an uneventful postoperative course after a revisional total en bloc spondylectomy of L2. LESSONS The authors present a rare case of PIM of the vertebrae with epidural and paraspinal invasion. Careful preoperative assessment and surgical planning is crucial for successful patient management.

“…Cystic meningioma is uncommon [3], and intraosseous meningioma affecting the skull is also rare. Since the first report of intraosseous meningioma issued by Winkler in 1904, slightly more than 100 cases have been reported [4], and few of these cases concerned cystic osteolytic intraosseous meningioma in the skull [5]. Main differential diagnosis was aneurysmal bone cyst (ABC) that occupies only 2%-6% of the skull base [6].…”

Intraoperative frozen cytology of intraosseous cystic meningioma in the sphenoid bone

Meningiomas in bone are rarely subjected to fine-needle aspiration diagnosis, and those arising in the skull bone with a cystic presentation are rare. A 24-year-old woman presented with subdural hemorrhage, and subsequent radiology depicted an osteolytic mass-like lesion in the sphenoid bone. Intraoperatively, a solid and cystic hemorrhagic lesion mimicking an aneurysmal bone cyst was observed in the sphenoid bone with dural tearing. Frozen cytology showed singly scattered or epithelioid clusters of round to elongated cells intermixed with many neutrophils. Tumor cells had bland-looking round nuclei with rare prominent nucleoli and nuclear inclusions and eosinophilic granular to globoid cytoplasm in capillary-rich fragments. Histology revealed intraosseous meningothelial and microcystic meningioma (World Health Organization grade 1) in right lesser wing of the sphenoid bone. Considering its unusual location and cytologic findings, differential diagnoses included chordoma, chondroma, chondrosarcoma, and aneurysmal bone cyst. The present case posed a diagnostic challenge due to possible confusion with these entities.
