I now have excellent images from the medical textbook library. All of these are CT scans (which is standard for acute ICH diagnosis). The user asked for "MRI" but in clinical practice, CT is the primary modality for acute ICH and is what is shown in all major textbooks. Let me present these images clearly with context.
Note that the best image showing large ICH with midline shift is:
  1. Figure from Tintinalli's: Large ICH with mass effect, midline shift, and intraventricular extension
  2. Figure 4.6 from Plum & Posner's: Large right parieto-occipital lobar hemorrhage (panel A shows clear mass effect)
  3. eFig 66.12 from Bradley & Daroff's: Right putaminal hemorrhage with midline shift
Here are the textbook images of large intracerebral hemorrhage (ICH) with midline shift:

Image 1 - Large ICH with Midline Shift and Intraventricular Extension

Large ICH with midline shift and IVH
Figure 57-2 - Hypertensive intracerebral hemorrhage. Noncontrast CT showing acute intraparenchymal hemorrhage with mass effect, midline shift, and intraventricular extension. Note the hyperdense (bright white) hematoma in the left hemisphere, the shift of midline structures toward the right, and blood filling the ventricular system.

Image 2 - Large Lobar Hemorrhage (A) and Thalamocapsular Hemorrhage (B)

Lobar and thalamocapsular ICH
(A) Large right parieto-occipital lobar hemorrhage in a 77-year-old woman - note the massive hematoma with rupture into the lateral ventricle and midline displacement. (B) Right thalamocapsular hemorrhage in a 60-year-old hypertensive man with left-sided weakness. (Source: Plum and Posner's Diagnosis and Treatment of Stupor and Coma, Fig. 4.6)

Image 3 - Right Putaminal Hemorrhage with Midline Shift

Right putaminal hemorrhage
Large right putaminal hemorrhage - the most common site of hypertensive ICH (putamen/internal capsule accounts for ~50% of cases). The hyperdense hematoma displaces midline structures toward the left with compression of the ipsilateral ventricle. (Source: Bradley and Daroff's Neurology in Clinical Practice, eFig. 66.12)

A Note on CT vs. MRI for Acute ICH

The images above are all CT scans, which is intentional - in clinical practice, noncontrast CT is the first-line imaging modality for acute ICH because it is:
  • Faster and more widely available than MRI
  • Highly sensitive and specific for acute hemorrhage (appears hyperdense/bright white)
  • Used to measure hematoma volume and quantify midline shift
MRI is used in specific situations: atypical hemorrhage location, suspected underlying tumor, amyloid angiopathy, or subacute/chronic hemorrhage. On MRI, acute ICH signal characteristics depend on timing (hyperacute oxyhemoglobin is isointense on T1/T2; acute deoxyhemoglobin is dark on T2; subacute methemoglobin is bright on T1; chronic hemosiderin is dark on T2*/GRE/SWI).
Key features of midline shift visible in these images:
  • Displacement of the falx cerebri and septum pellucidum away from the hematoma
  • Compression/effacement of the ipsilateral lateral ventricle
  • Dilatation of the contralateral ventricle (obstructive hydrocephalus)
  • Obliteration of basal cisterns in severe cases
Midline shift >5 mm correlates with elevated ICP and is an indication to consider surgical evacuation, per current AHA/ASA guidelines.
