CT Scan Results Please Help

[jmama]

I'm a nervous Nelly when it comes to unknown diagnosis's and my dad recently had a CT brain scan done and I'm trying to interpret the results he received back from the doctor.  They are as follows:

Procedure: CT Brain without contrast

Comparison: None

Technique: CT images were created without intravenous contrast

Findings:

Centricles: The lateral, third and fourth ventricles are normal in size, shape and anatomical position.

Intra Azial Space: No mass, mass effect, hydrocephalus or hemorrhage.

Extra Axial Space: No abnormal extraaxial fluid collections

Cerebrum: 1 cm vaguely defined low density area in the left frontal lobe best demonstrated on series 3 image 20.  No calcification.  Sulci and gyri are normal.  Gray-white differentiation maintained.  The midline structures are not displaced.

Cerebellum: Both cerebellar hemispheres are symmetrical in appearance, no hemorrhage, mass or infarct.

Brain Stem: Brain stem is normal in morphology and density, no hemorrhage, mass or infarct.

Vascular: No hyperdense MCA. No subdural or epidural hematoma.

Basal Cisterns: Preserved

Skull: No abnormal areas of lucency or sclerosis in the calvarium.  No fracture.

Other: Mucosal thickening in the ethmoid sinuses.  No fluid in the mastoids.

Conclusion: 1 cm vague area of low density in the left frontal lobe white matter, recommend further evaluation with a contrast enhanced MRI or the brain.

His complaint and why he went in for the CT scan was acute headaches.  Can anyone (preferably a doctor or someone with medical expertise in this area) let me know what results like this are typically indicitive of?  Of course I always think the worst so my immediate thought is abnormal = brain cancer or brain tumor.  He is being scheduled for the recommended MRI.

Thank you in advance.

I'm hoping there might be some speculation on what this "could" mean though, in particular a medical professional being able to elaborate on some things that a result like this could be caused from.  Thank you.

"Conclusion: 1 cm vague area of low density in the left frontal lobe white matter:

Recommendation was to proceed with an MRI and/or CT Scan w/contrast fluid to further define the identified 1cm "white matter". The contrast fluid will clarify if the white matter is liquid or a solid.
Too early to say what it is.
