Multiple sclerosis and oligodendroglioma: an exceptional association

Area of Science:

• Neuroscience
• Oncology
• Neuropathology

Background:

• Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
• Oligodendroglioma is a type of primary brain tumor arising from oligodendrocytes.
• The simultaneous occurrence of MS and oligodendroglioma is exceptionally rare in clinical practice.

Purpose of the Study:

• To report a rare case of oligodendroglioma in a patient with a long-standing diagnosis of multiple sclerosis.
• To highlight the diagnostic challenges posed by the co-occurrence of these two conditions.
• To emphasize the importance of considering brain tumors in MS patients presenting with atypical neurological symptoms.

Main Methods:

• Case presentation of a 43-year-old male with a 14-year history of MS.
• Review of cerebral MRI findings showing an extensive lesion initially misdiagnosed as tumefactive demyelinating lesion.
• Histopathological examination of a cerebral biopsy confirming oligodendroglioma.

Main Results:

• The patient, diagnosed with MS for 14 years, developed seizures and right hemiparesis.
• Cerebral MRI revealed a lesion previously misdiagnosed as tumefactive demyelinating lesion.
• Cerebral biopsy confirmed oligodendroglioma, which was successfully treated with radiotherapy.

Conclusions:

• Diagnosing a brain tumor in a patient with multiple sclerosis is complex.
• Atypical clinical presentations and radiological features are critical for accurate diagnosis.
• The possibility of a brain tumor must be considered even in rare associations with MS.
