The T2-weighted magnetic resonance imaging of the pelvis shows several bone metastases. The metastases are visible as hypointense lesions within the pelvis bilaterally and the sacrum

At age 63 and 11 years following craniotomy, a magnetic resonance imaging (MRI) of the pelvis showed a multitude of small skeletal lesions suggestive of metastases [Figure 1].
The contrast-enhanced computed tomography scan of the abdomen shows several metastases in the liver 17 years following craniotomy. The metastases are visible as contrast enhancing and hypodense lesions mostly within the right lobe

At the time of the second radiosurgery treatment, liver metastases of the meningioma were suspected in a computed tomography (CT) scan and was confirmed bioptically [Figure 2].
The sagittal bone window computed tomography scan of the thoracic spine shows several metastases in the vertebrae 17 years following craniotomy. The metastases are visible as hypodense lesions within the vertebrae

In addition, a multitude of vertebral metastases were diagnosed by CT scan at that time [Figures 3 and 4].
The sagittal bone window computed tomography scan of the lumbar spine shows several metastases in the vertebrae 17 years following craniotomy. The metastases are visible as hypodense lesions within the vertebrae

In addition, a multitude of vertebral metastases were diagnosed by CT scan at that time [Figures 3 and 4].
The T1-weighted sagittal magnetic resonance imaging of the lumbar spine shows a multitude of bone metastases within the vertebra and the sacrum 18 years following craniotomy. The metastases are visible as contrast enhancing and hypointense lesions within the vertebrae

At the time of the last follow-up 18 years after craniotomy and at 70 years of age, bone metastases of the lumbar spine were monitored by an MRI [Figure 5].
The T1-weighted contrast-enhanced axial magnetic resonance imaging of the head shows a stable tumor rest attached to the right tentorium 18 years following craniotomy. The residual tumor is the small contrast enhancing nodule adjacent to the tentorium and the right tentorial sinus

The tumor remnants of the posterior fossa were stable at the current follow-up 18 years after craniotomy or 6 and 1 years following the two radiosurgery treatments [Figure 6].
