MRI Brain with Venogram - Interpretation Report

Patient: DILESWAR NAIK | Age/Sex: 49 years / Male | DOB: 12-07-1977 Date of Study: 12-07-2026 Institution: SUM Ultimate Medicare, Bhubaneswar Sequences Reviewed: MRV (3D MIP), T1 Axial, T2 Axial, T2 Coronal, T2 Sagittal, DWI, FLAIR, SWI

FILM 1 - MR Venogram (MRV - 3D MIP Reconstructions)

Superior Sagittal Sinus (SSS): Fully visualized from its anterior origin to the posterior confluence. Bright, continuous signal throughout - no filling defects or thrombosis.
Confluence of Sinuses (Torcular Herophili): Well-formed and patent at the posterior junction of SSS, straight sinus, and transverse sinuses.
Transverse Sinuses:
  • Right transverse sinus: dominant, good caliber with bright signal - normal.
  • Left transverse sinus: patent but relatively smaller than the right - this is a common normal anatomical variant (right-sided dominance occurs in ~60-70% of the population). No abrupt cutoff or filling defect to suggest thrombosis.
Sigmoid Sinuses & Internal Jugular Veins: Smooth, continuous drainage bilaterally. No stenosis or thrombosis.
Straight Sinus: Visualized with normal signal on sagittal projections. Patent.
MRV Impression: No evidence of cerebral venous sinus thrombosis (CVST). Mild physiological asymmetry of the transverse sinuses (right dominant).

FILM 2 - T1 Axial & T2 Axial

Brain Parenchyma: Normal grey-white matter differentiation throughout the cerebral hemispheres. No focal cortical lesions.
White Matter: No T2 hyperintensities suggesting microvascular ischemic disease, demyelination, or leukoencephalopathy.
Ventricular System: Lateral ventricles, third and fourth ventricles - symmetric, normal in size and configuration. No hydrocephalus.
Basal Ganglia & Thalami: Symmetric. Normal signal bilaterally. No lacunar infarcts or mineralization.
Cerebellum & Brainstem: Normal foliation of cerebellum. Brainstem (midbrain, pons, medulla) - normal morphology and signal. No tonsillar herniation.
T1/T2 Axial Impression: Normal.

FILM 3 - T2 Coronal & T2 Sagittal

Corpus Callosum: Fully formed - rostrum, genu, body, and splenium all of normal thickness and morphology. No thinning or signal abnormality.
Ventricular System: Normal on coronal projections - no asymmetry or compression.
Posterior Fossa: Cerebellopontine angles clear. Normal cerebellar vermis and hemispheres.
Brainstem: Normal internal architecture on sagittal views.
T2 Coronal/Sagittal Impression: Normal. No mass, edema, or abnormal signal identified.

FILM 4 - DWI, FLAIR, and SWI

DWI (Diffusion Weighted Imaging): No areas of restricted diffusion (no bright focal signal) in any vascular territory - cerebrum, basal ganglia, thalami, cerebellum, or brainstem. Rules out acute ischemic infarction.
FLAIR: No periventricular or deep white matter hyperintensities. No cortical edema or gliosis. Ventricles and sulci normal for age.
SWI (Susceptibility Weighted Imaging): No blooming artifacts (signal dropout) in brain parenchyma. No microbleeds, no hemorrhage, no hemosiderin deposits. Venous structures appear normal without engorgement.
DWI/FLAIR/SWI Impression: Normal. No acute infarct, no hemorrhage, no microangiopathy.

OVERALL IMPRESSION

MRI Brain with MR Venogram - Grossly Normal Study
  1. No cerebral venous sinus thrombosis (CVST) - all major dural sinuses are patent with normal flow signal.
  2. No acute ischemic stroke - DWI is normal.
  3. No intracranial hemorrhage or microbleeds - SWI is clear.
  4. No space-occupying lesion, mass effect, or midline shift.
  5. No demyelinating disease - no MS-type plaques on FLAIR/T2.
  6. No significant white matter ischemic changes for a 49-year-old.
  7. Mild right-dominant transverse sinus asymmetry - normal variant, not pathological.
Important Note: This interpretation is based on photographic images of the MRI films. A formal radiological report requires evaluation of full-resolution DICOM data by a qualified radiologist, correlated with the patient's clinical history, symptoms, and indication for the scan. Please consult your treating physician and radiologist for the official diagnosis and management plan.
