Remote Assessment: The Right Diagnosis First
Before a cross-border journey, you can request an online preliminary assessment by digitally sharing your brain MRI including sequences sensitive to cavernoma (especially SWI/GRE) and any prior imaging via WhatsApp. At this stage the aim is to evaluate whether the lesion really is a cavernoma, its location, number and whether it carries signs of previous bleeding, and to discuss honestly whether observation or surgery comes into consideration. Comparison with older MRIs is very valuable in showing whether the lesion has changed over time.
Not Every Cavernoma Requires Surgery
A significant proportion of cavernomas cause no symptoms and are found incidentally; in this case the right approach is most often observation (wait-and-watch) with serial MRI. Surgery comes to the fore when the cavernoma has bled, causes drug-resistant seizures, produces progressive neurological symptoms, or lies in a superficial and safely accessible location. In brainstem or deep-seated cavernomas the decision is made far more carefully, because surgery carries a higher risk in these regions and the benefit-risk balance is weighed separately for each case. For this reason, before planning a long journey we determine together the right step for your cavernoma.
Surgery: Aim and Method
When surgery is found appropriate, the aim is to remove the cavernoma that is the source of bleeding or seizures completely, with the least damage to the surrounding brain tissue; incomplete removal may leave a continued risk of re-bleeding. In locations near critical areas such as speech, movement or vision, functions are protected with methods such as neuronavigation, intraoperative monitoring and, when needed, awake surgery. Unlike in vascular malformations, Gamma Knife radiosurgery plays a limited and debated role in cavernoma; for this reason it is not appropriate in every case and is selected carefully.
How the Process Works in Turkey
If the remote assessment suggests an intervention is possible, the additional tests needed and the estimated length of stay are planned before your arrival. On arriving in Turkey, an in-person neurological examination, mapping of critical pathways with functional MRI and DTI tractography when needed, and a multidisciplinary evaluation are carried out. Surgery is usually performed under general anaesthesia and requires a few days of hospital stay; in patients presenting with seizures, antiepileptic treatment is planned. At discharge a written summary is prepared for the follow-up MRI plan, seizure/neurology follow-up and the observation to be continued in your home country.
Honest Expectations and Multilingual Communication
A cavernoma is a benign vascular structure, but the aim of treatment is to reduce the risk of new bleeding or seizures, and no outcome can be guaranteed. The risks of surgery depend on the cavernoma's location (the risk of a neurological deficit is higher especially in brainstem and deep locations) and are discussed openly; in some situations it is honestly said that observation is safer than surgery. For a patient coming from across a border, the most critical point is that this benefit-risk balance is clearly understood in their own language; the decision is made together with you after all your data have been seen.
