Diagnosis
Recurrent oligodendroglioma of the left temporal lobe, WHO Grade II. Status post-radiotherapy and primary surgical resection.
Patient:
Female, 34 years old, Kazakhstan
Physician:
Prof. Dr. med. Martin Scholz, Head of Neurosurgery Department, Sana Hospital Duisburg
Expert Opinion by Prof. Martin Scholz (Initial Consultation upon Tumor Discovery):
I have carefully evaluated the provided brain MRI scans. The space-occupying lesion, or more accurately, the tumor, currently demonstrates clear anatomical boundaries in its left temporodorsal region. In this specific area, the tumor is very amenable to resection, and I would recommend debulking the majority of the mass here.
However, imaging shows a subtle area of contrast enhancement surrounding the tumor margin, suggesting that the lesion may unfortunately be undergoing malignant transformation. During surgery, we will naturally employ real-time intraoperative ultrasound, 3D neuronavigation, and continuous neurophysiological monitoring.
Initial Treatment Rendered:
The patient underwent a microsurgical resection of the left temporal lobe glioma guided by 3D neuronavigation and intraoperative neurophysiological monitoring. The surgery and postoperative recovery were uneventful and free of complications. Definitive histopathological analysis confirmed a WHO Grade II oligodendroglioma. On the tenth postoperative day, the patient was discharged in good clinical condition under the care of her local medical team. A follow-up MRI scan in 3 months was recommended to guide further management.
Expert Opinion by Prof. Martin Scholz (Follow-up MRI Review):
The patient reports ongoing headaches, reduced concentration, and memory impairment. Follow-up MRI scans obtained four months postoperatively demonstrate contrast enhancement surrounding the resection cavity, which, unfortunately, strongly suggests recurrent tumor growth. Distinguishing true tumor recurrence from radiation effects can be challenging, as the patient previously underwent extensive radiation therapy, which can induce radiation necrosis with a similar radiologic appearance.
In my clinical judgment, however, this progression may represent a high-grade transformation, such as a glioblastoma. I advise a repeat surgical resection extending into the temporal lobe region, as the imaging demonstrates suspicious contrast-enhancing tissue slightly beyond the primary resection cavity.
Preliminary Cost Estimate: €25,000
Subsequent Treatment Rendered:
A repeat microsurgical tumor resection was performed via a left parietal osteoplastic craniotomy. To precisely visualize tumor margins and distinguish neoplastic tissue from healthy brain parenchyma, 5-ALA fluorescence-guided visualization was utilized alongside intraoperative ultrasound control. The procedure and postoperative recovery proceeded without complications. On the tenth postoperative day, the patient was discharged from the hospital in good clinical condition for ongoing outpatient care.
Actual Cost of Treatment: €24,221
