ICF Impairments — Mr. Pawar Suresh Gangaram (77M, Left MCA Territory Infarct)
Imaging Summary:
- MRI (30/03/2026): Hyperacute–acute non-hemorrhagic left MCA territory infarct (fronto-parieto-temporal cortex + subcortical WM + capsulo-ganglionic region + insular cortex); chronic lacunar infarct left centrum semiovale; bilateral small vessel ischemic changes (Fazekas Grade I); suspected left transverse & sigmoid sinus thrombosis; generalized cerebral & cerebellar atrophy
- MRA: Left ICA and left MCA — loss of flow (occlusion); left vertebral artery — proximal occlusion; left ACA filling via ACoA collateral
- CT (04/04/2026): Subacute infarct progression in same territory with perilesional edema; diffuse osteopenia; right eye — suspected phthisis bulbi
A. BODY STRUCTURE IMPAIRMENTS (ICF Chapter s1 — Structures of the Nervous System)
| # | ICF Code | Structural Impairment | Imaging Evidence | Clinical Reasoning |
|---|---|---|---|---|
| 1 | s110 | Left fronto-parieto-temporal cortical infarct (large territory) | MRI: DWI restriction + FLAIR hyperintensity in left fronto-parieto-temporal cortex and subcortical WM | Left ICA + MCA occlusion → abrupt loss of blood supply → ischemic necrosis of neurons in the cortex within 6 hours; no reperfusion → established infarct |
| 2 | s110 | Left capsulo-ganglionic region infarct | MRI: DWI restriction in left internal capsule / ganglionic region | The lenticulostriate arteries (perforators of MCA) were cut off by left MCA occlusion → infarction of posterior limb of internal capsule and basal ganglia region |
| 3 | s110 | Left insular cortex infarction | MRI: insular cortex involvement noted | Insular cortex is deep MCA territory; occlusion of proximal MCA → ischemia of insula (involved in autonomic regulation, swallowing, speech) |
| 4 | s110 | Chronic lacunar infarct — left centrum semiovale | MRI + CT: chronic lacunar infarct, centrum semiovale | Long-standing hypertension / small vessel disease → lipohyalinosis of small perforators → lacunar infarction of corona radiata fibers |
| 5 | s110 | Chronic small vessel ischemic changes bilateral (Fazekas Grade I) | MRI: bilateral centrum semiovale, corona radiata, periventricular T2/FLAIR hyperintensities | Chronic hypertension and atherosclerosis → diffuse white matter microangiopathy → demyelination and axonal loss in deep WM |
| 6 | s110 | Left transverse & sigmoid sinus thrombosis (suspected) | MRI: FLAIR increased signal in left transverse and sigmoid sinus | Hypercoagulable state, dehydration, or extension of thrombus from ICA → venous outflow obstruction → increased venous pressure, cytotoxic/vasogenic edema |
| 7 | s110 | Generalized cerebral and cerebellar atrophy | CT + MRI: prominent sulcal spaces, fissures, basal cistern, cerebellar folia | Age-related neurodegeneration (77 years) + chronic cerebrovascular disease → progressive cortical and cerebellar volume loss |
| 8 | s750 | Diffuse osteopenia | CT: diffuse osteopenia noted throughout skull | Age-related bone mineral density loss (senile osteopenia) + likely immobility, nutritional deficiency, and possible low testosterone in elderly male |
| 9 | s220 | Right eye — suspected phthisis bulbi (lens calcification, retinal detachment, globe calcification) | CT: lens calcification, retinal detachment, peripheral globe calcification right eye | End-stage ocular disease (chronic hypotony/ischemia/trauma/inflammation) → globe shrinkage, calcification of intraocular structures → loss of eye structure integrity |
B. BODY FUNCTION IMPAIRMENTS (ICF Chapter b1–b7)
| # | ICF Code | Functional Impairment | Neuroanatomical Basis | Clinical Reasoning |
|---|---|---|---|---|
| 1 | b730 | Right-sided hemiplegia / severe hemiparesis (upper + lower limb) | Left posterior limb of internal capsule + left primary motor cortex (M1) infarct | Corticospinal tract passes through posterior limb of internal capsule → MCA territory infarct destroys upper motor neurons → contralateral (right) spastic hemiplegia |
| 2 | b735 | Increased muscle tone / spasticity (right side) | Upper motor neuron lesion — loss of descending inhibition | UMN lesion removes inhibitory input on spinal interneurons → velocity-dependent hypertonicity (spasticity), hyperreflexia, Babinski sign on right |
| 3 | b710 | Reduced joint mobility / ROM (right upper and lower limbs) | Consequence of hemiplegia + spasticity | Immobility + spasticity → periarticular fibrosis, muscle shortening → restricted passive and active ROM |
| 4 | b760 | Impaired control of voluntary movement (right side) | Destruction of left motor cortex and corticospinal projections | Loss of fine motor control, coordination, and voluntary activation of right limbs — inability to perform skilled or goal-directed movements |
| 5 | b280 | Contralateral hemisensory loss (right side — touch, proprioception, pain) | Left parietal cortex (somatosensory cortex, S1, S2) infarction | Primary and secondary somatosensory cortices lie in the parietal lobe (MCA territory) → loss of discriminative touch, proprioception, and pain on right body |
| 6 | b167 / b320 | Aphasia (expressive / global) | Left fronto-temporal cortex — Broca's area (IFG) + Wernicke's area (STG) | Dominant (left) hemisphere infarct involving Broca's area (BA44/45) and likely Wernicke's area → global or Broca's aphasia; impaired speech production and/or comprehension |
| 7 | b330 | Dysarthria | Involvement of left motor cortex and insular cortex | Insular cortex + motor cortex supply articulation muscles; infarction → imprecise, slurred, slow speech (supranuclear dysarthria) |
| 8 | b510 | Dysphagia | Left insular cortex + opercular cortex infarction | Swallowing cortex lies in the insular and frontal opercular regions — bilateral representation, but unilateral large infarct → aspiration risk, pharyngeal phase impairment |
| 9 | b114 / b144 | Cognitive impairment (attention, memory, executive function) | Large left frontal + parietal infarct + generalized atrophy + chronic WM disease | Prefrontal cortex and parietal association cortex destruction + diffuse WM disconnection → impaired working memory, attention, executive planning, and orientation |
| 10 | b156 | Perceptual dysfunction / spatial neglect | Right parietal involvement is less likely here, BUT insular + parietal left involvement may cause body schema disturbance | Left parieto-insular infarct can cause left-sided awareness deficits; right-sided inattention less prominent with left lesion, but body image disturbance possible |
| 11 | b410 / b420 | Autonomic dysregulation (heart rate, blood pressure instability) | Left insular cortex infarction — central autonomic network | The insular cortex is the primary cortical autonomic integration center → left insular infarct disrupts cardiac autonomic modulation → risk of arrhythmia, BP lability, and cardiac events |
| 12 | b620 | Bladder dysfunction (neurogenic bladder — urinary incontinence or retention) | Left frontal and insular cortex + internal capsule | Frontal micturition center and corticospinal projections to sacral detrusor centers are disrupted → loss of voluntary bladder inhibition → urge incontinence or retention |
| 13 | b730 / b235 | Vestibular/balance impairment + postural instability | Cerebellar atrophy + possible left vertebral artery involvement | Generalized cerebellar atrophy and left VA proximal occlusion → impaired cerebellar regulation of tone and balance → truncal ataxia and postural sway |
| 14 | b210 | Severe visual impairment right eye | Right eye phthisis bulbi | End-stage atrophy of right globe → loss of light perception or no useful vision in right eye; combined with possible left homonymous hemianopia (right occipital sparing usual in MCA stroke but parietal visual pathway affected) |
| 15 | b710 | Bone fragility / fracture risk | Diffuse osteopenia | Reduced bone mineral density in 77-year-old with immobility → high risk of fragility fractures (especially hip, vertebral) during physiotherapy and transfers |
C. SUMMARY — KEY ICF IMPAIRMENT CLUSTERS
| Cluster | Primary Lesion Responsible | Functional Impact |
|---|---|---|
| Motor (b730, b735, b760) | Left M1 + posterior limb internal capsule (MCA perforators) | Right hemiplegia + spasticity |
| Sensory (b280) | Left S1/S2 parietal cortex | Right hemisensory loss |
| Communication (b167, b320, b330) | Left Broca's/Wernicke's (fronto-temporal) | Aphasia + dysarthria |
| Swallowing (b510) | Left insular + opercular cortex | Dysphagia (NG tube in situ confirms this) |
| Cognition (b114, b144, b156) | Left frontal + parietal + diffuse WM | Attention, memory, executive dysfunction |
| Autonomic/Bladder (b410, b620) | Left insular + frontal cortex | Cardiac instability, neurogenic bladder |
| Balance/Posture (b235, b755) | Cerebellar atrophy + left VA occlusion | Postural instability |
| Vision (b210) | Right phthisis bulbi | Monocular blindness right eye |
| Bone (b710) | Diffuse osteopenia (systemic) | Fracture risk during mobilization |
Clinical Note: The presence of an NG tube in situ on CT confirms clinically significant dysphagia/aspiration risk. The left ICA + MCA complete occlusion explains the large, severe infarct pattern. The coexisting chronic small vessel disease and prior lacunar infarct suggest pre-existing cerebrovascular disease, which likely exacerbates the current functional deficits beyond what the acute infarct alone would produce.
