Cavernoma Treatment in MVZ Gamma Knife Center Krefeld & Hanover
About the clinic
Cavernoma care at MVZ Gamma Knife Center Krefeld & Hanover in Germany includes imaging and stereotactic radiosurgery. Gamma Knife radiosurgery may cost around $4,500–$11,200 per treatment course. The center has used radiosurgery since 1998 and holds DIN EN ISO 9001:2015 certification.
Imaging and treatment planning
Imaging helps assess the lesion and plan treatment. Available tests and imaging tools include:
- Contrast-enhanced thin-slice MRI for detailed brain images.
- Digital subtraction angiography (DSA) for images of blood vessels.
- PET-CT with Gallium 68 (DOTATATE).
- Integrated CT for stereotactic linear accelerator treatment.
Gamma Knife treatment planning may use MRI, CT, and DSA. The center’s Gamma Knife Icon includes integrated cone beam CT.
Radiosurgery options for cavernoma
- Gamma Knife radiosurgery treats vascular malformations, ideally those under 2.5 cm. It can use a fixed frame in one session or a mask over 4–5 days. The stated dose is 18–25 Gy, including 20–25 Gy for vascular malformations. A session lasts 30–120 minutes and is described as painless and silent. Treatment is outpatient or involves a short hospital stay.
- Stereotactic LINAC radiotherapy uses the Axesse linear accelerator with integrated CT. Fractionated or hypofractionated treatment is an option for very large or deep vascular lesions.
The center reports a 70–80% occlusion rate for vascular malformations. Imaging typically confirms occlusion 1–3 years after treatment. This reported rate is for vascular malformations and is not a guaranteed result for an individual cavernoma.
Dr. med. Frank Sonnenschein, a neurosurgery and radiosurgery specialist, has over 25 years of experience. He has practiced radiosurgery at the center since 2017 and is a senior physician there. For inpatient neurosurgical care, the center cooperates with Helios Hospital Krefeld.
Patients can request a consultation through Bookimed to discuss imaging and treatment options.

MVZ Gamma Knife Center Krefeld & Hanover: more details about the clinic
Specialized Achievements and Quality Standards
The center has completed over 10,000 successful treatment courses since opening. This volume includes therapy for benign and malignant tumors requiring extreme precision. In March 2025, the facility received DIN EN ISO 9001:2015 re-certification after rigorous audits.
The clinic is recognized as a Great Place To Work® in Germany. It maintains close cooperation with Helios Hospital Krefeld. This partnership gives patients access to neurosurgical beds if inpatient care becomes necessary. The medical team includes 10 doctors – neurosurgeons and radiation therapy specialists.
Radiosurgery and Stereotactic Radiotherapy
The clinic specializes in non-invasive alternatives to traditional brain and body surgery. For patients with acoustic neuroma, radiosurgery treats the tumor without opening the skull. This method destroys tumor cells while sparing surrounding healthy tissue.
Specialists also treat arteriovenous malformation (AVM) – tangles of abnormal blood vessels in the brain. The center reports a 70–80% occlusion rate for these malformations. Occlusion typically appears on imaging one to three years after treatment.
The oncology department manages various conditions:
- Brain and spinal metastases
- Meningiomas (dural membrane tumors)
- Pituitary adenomas
- Liver and lung metastases
- Trigeminal neuralgia (nerve pain)
For brain metastases, the center can treat up to ten lesions in a single session. This offers a targeted alternative to whole-brain radiation therapy.
Advanced Imaging and Treatment Technology
The clinic uses Gamma Knife Icon technology for high-precision treatment in the head and neck. This system includes an integrated cone beam CT for real-time accuracy. For tumors elsewhere in the body, specialists use a stereotactic linear accelerator (LINAC).
Diagnostic imaging is built into the planning process to ensure exact dosing. The facility uses several imaging platforms:
- Contrast-enhanced thin-slice MRI
- PET-CT with Gallium 68 (DOTATATE)
- Digital subtraction angiography (DSA)
- Integrated computer tomograph for LINAC
Images transfer directly to the treatment planning software via PACS. This allows the team to map exact tumor coordinates before irradiation begins.
Support and Services for International Patients
International patients can use a dedicated online upload portal to submit radiological findings. Specialists review these images before the first consultation to determine treatment suitability. The center accepts medical documents in German, English, and French.
After treatment, the clinic provides structured follow-up care based on the condition. Cancer patients typically receive brain MRI examinations three times per year. Those treated for AVM undergo regular imaging to confirm vessel occlusion. Most radiosurgery patients return to work within 2–3 days.
