Hemiatrophy and glioblastoma.

Area of Science:

• Neurology
• Oncology
• Pathology

Background:

• Brain tumors rarely present with ipsilateral secondary brain atrophy.
• Existing literature documents only 10 such cases, all from Japan.

Observation:

• This report describes a novel case of primary cerebral hemiatrophy.
• The hemiatrophy was associated with an ipsilateral glioblastoma.

Findings:

• The co-occurrence of primary cerebral hemiatrophy and ipsilateral glioblastoma is unprecedented in medical literature.
• This finding challenges existing understandings of tumor-induced brain changes.

Implications:

• Highlights the need for broader case reporting in neuro-oncology.
• May prompt further research into the mechanisms underlying tumor-associated brain atrophy.
• Contributes to the differential diagnosis of rare neurological conditions.
