Tumefactive demyelinating lesions (TDLs), are a rare demyelinating pathological
disease in the central neurological system, which have been proven to be a
diagnostic dilemma to neurosurgeons. The clinical presentation and radiographic
appearance of these lesions often results in their misdiagnosis as intracranial
tumors, such as gliomas, which leads to unnecessary surgical resection and
adjunct radiation. In the present study, the clinical and radiographic features
of 14 patients with cerebral TDLs who underwent surgical treatment between
January 2004 and January 2009 were reviewed and analyzed. The surgical methods
used included biopsy and resection, while steroid therapy was indicated when TDLs
were confirmed by histopathological analysis. The patients were followed-up and
the outcomes were evaluated using the Karnofsky performance scale (KPS). The main
clinical presentations included: Hemiplegia (8 cases), increased intracranial
pressure (4 cases) and seizures (general in 1 case; partial in 3 cases). On
magnetic resonance imaging scans, 12/14 TDL cases demonstrated an isolated local
subcortical mass and 6/14 cases (42.9%) demonstrated enhancing veins coursing
undistorted through the lesion. The postoperative complications included:
Hemiplegia (2 cases) and mortality (1 case). A total of 9 cases underwent
microsurgical total resection, and 5 cases received stereotactic biopsy that was
followed with high-dose methylprednisolone therapy. The follow-up study
demonstrated that 2 cases presented recurrence with multiple sclerosis and the
KPS scores for 13/14 patients (92.9%) were ?80. In conclusion, the clinical and
radiographic features of TDLs may help to establish the correct diagnosis prior
to surgery, in order to avoid unnecessary resection or adjunctive therapy. Using
steroid therapy, the majority of patients with TDLs appeared to achieve
satisfactory prognosis.
