Summary of cases from the literature review

Reference	Study type	Sample size	Age	Gender	Symptoms	Imaging	Surgical technique	Outcomes
Das8	Case report	1	45	F	Quadriparesis with diffuse hyperreflexia.	MRI: Craniocervical meningioma with cord compression.	Midline suboccipital craniectomy	Simpson grade I tumour resection with C1-2 laminectomy. Significant improvement in symptoms at 2-month follow-up
Abolfotoh et al9	Case report	1	37	F	5 years of progressive right upper extremity numbness and weakness, right facial numbness, and occipital pain.	MRI: Large calcified mass at the right posterior-lateral margin of the craniocervical junction, encasing the right vertebral artery and right PICA loop	Resection of the tumour was done using the transcondylar approach	Successful resection with no recurrence at 14 months postoperatively.
Lilla et al10	Case Series	4	Mean: 65	F (4)	Head and neck pain (1). Paresthesia (1). Gait ataxia (1). Recurrent syncope (1).	Tumours were located from the clivus to C2.	Resection of anteriorly located upper cervical and lower clivus meningiomas without laminotomy or craniotomy using a minimally invasive posterior approach	Simpson grade II tumour resection. No tumour reccurence or spinal instability at the 7–28 months follow-up period.
Dührsen et al11	Retrospective cohort	18	Mean:52	F (14) M (4)	Pain (3). Sensory/motor disability (11). Lower CN palsy (3). Incidental (1).	Tumours were located between C0 and C2 in ten patients, at the level of the foramen magnum in three patients, and at the level of clivus, extending caudally in five patients.	Retrosigmoidal (1), suboccipital midline (11), suboccipital midline with lateral extension (6), with additional laminectomy of C1.	Simpson grade II (16), Simpson grade III (2). At follow-up one patient had two reccurences at one and 3 years postoperatively.
