Could the following MRI report explain recurrent "right hemisphere headaches?"

MRI BRAIN WITHOUT CONTRAST

INDICATION: Malaise and fatigue, CLL, cognitive impairment

TECHNIQUE: MRI of the brain performed without contrast.

FINDINGS: There is no diffusion restriction to suggest acute or
recent ischemia. The ventricles and sulci are normal in caliber and
contour. The midline structures including the corpus callosum
pituitary gland, optic chiasm, pineal gland, and cerebellar tonsils
appear normal. There is no intracranial hemorrhage or mass effect. A
linear focus of diminished signal intensity on T1 and T2-weighted
images is seen traversing the right parietal lobe. Minimal adjacent
FLAIR hyperintensity can be seen here. This likely represents a
developmental venous anomaly. Aside from this focal area of elevated
FLAIR signal there is normal signal intensity seen within the gray
and white matter. The flow-voids of major arteries at the skull base
are preserved. The flow-voids of major dural venous sinuses are
present on T2-weighted imaging. Paranasal sinuses are aerated. Globes
and orbits are unremarkable.

IMPRESSION: NO ACUTE ABNORMALITY. SUSPECTED RIGHT PARIETAL
DEVELOPMENTAL VENOUS ANOMALY.
