Radiologist Misses Meningioma on MRI

Case Overview

This case involves the missed diagnosis of a meningioma that was approximately 2.3 x 1.5 cm. The mass was not identified by a radiologist on his initial interpretation of an MRI of the head. Two years after the initial screening, the diagnosis was made due to a major seizure episode that warranted more imaging studies of the patient’s brain. Because of the invasive state of the mass, the neurosurgeon was only able to remove 90% of the tumor, and could not use stereotactic brain surgery. There was no way for the surgeon to remove or treat the entire tumor, as it had wrapped around the optic nerve. Following the procedure, and delayed diagnosis, the patient suffered from persistent diplopia and blurry vision, among other complications.

Questions to the Neurosurgery expert and their responses

What is the survival rate for this condition if caught at an early stage?

Patients whose meningiomas are completely resected usually have an excellent prognosis.
