Differential Diagnosis for 37-year-old Male with Seizure and Headache

Single Most Likely Diagnosis

  • Glioblastoma: Given the patient's presentation with a seizure, frequent headaches, and a single mass lesion in the right hemisphere with surrounding vasogenic edema on imaging, glioblastoma is a highly likely diagnosis. It is a common primary CNS tumor in adults, known for its aggressive nature and potential to cause seizures and focal neurological deficits.

Other Likely Diagnoses

  • Meningioma: Although typically benign, meningiomas can cause seizures, headaches, and focal neurological deficits due to their location and potential to compress adjacent brain tissue. Their presence in the right hemisphere could explain the patient's symptoms.
  • Metastatic Brain Tumor: Given the patient's age and occupation, while there's no mention of a primary cancer, metastatic brain tumors are a possibility, especially if the patient has an undiagnosed primary malignancy. They can present with seizures, headaches, and focal deficits.
  • Oligodendroglioma: A type of glioma that can present with seizures and is often found in the cerebral hemispheres. It might not be as aggressive as glioblastoma but can still cause significant symptoms.

Do Not Miss Diagnoses

  • Cerebral Abscess: Although less likely given the description of the mass lesion, a cerebral abscess could present with similar symptoms, including seizures and focal neurological deficits. It's a medical emergency requiring prompt treatment.
  • Hemorrhagic Stroke: The initial presentation could mimic a hemorrhagic stroke, especially if the mass lesion has bled. This would be a critical diagnosis not to miss due to the need for urgent intervention.
  • Infectious Causes (e.g., Neurocysticercosis, Toxoplasmosis): Infections can cause mass lesions and seizures. While less likely in this immunocompetent patient, they are crucial not to miss due to their treatability.

Rare Diagnoses

  • Primary CNS Lymphoma: A rare tumor that can present with neurological symptoms, including seizures. It's more common in immunocompromised patients but can occur in anyone.
  • Hemangioblastoma: Typically associated with von Hippel-Lindau disease, these tumors are rare and can present with seizures and mass effect.
  • Ganglioglioma: A rare, usually benign tumor that can cause seizures. It's often found in younger patients and can be associated with a good prognosis if completely resected.
