Based on careful review of the CT head series, here is my radiological analysis:
CT Head — Radiological Report & Diagnosis
Patient: Darshan Singh, SAY M | Age: ~52 years | Non-contrast CT Brain
Key Findings
Row 2 (basal ganglia level) — most critical finding:
There is a focal hyperdense (bright white) lesion in the right basal ganglia / putaminal region, seen clearly in the right-sided image of row 2. This acute hyperdensity is characteristic of fresh blood clot on non-contrast CT (blood has a Hounsfield unit value of ~50–80 HU, making it brighter than normal brain parenchyma).
Ventricular system: The lateral ventricles appear mildly prominent. There is early effacement of the right lateral ventricle, consistent with mild mass effect from the hemorrhage.
Midline: Mild midline shift toward the left is suggested.
Cortical sulci: Preserved at the vertex, arguing against significant diffuse cerebral edema.
Posterior fossa / cerebellum: No obvious cerebellar hemorrhage or herniation.
Bone windows (rows 6–7): No obvious skull fracture or bony defect.
Primary Diagnosis
Right Basal Ganglia (Putaminal) Intracerebral Hemorrhage (ICH)
This is the classic location and CT appearance of hypertensive hemorrhagic stroke — the putamen / basal ganglia is the most common site (~35% of all spontaneous ICH), supplied by the lenticulostriate arteries, which are highly susceptible to hypertensive changes.
Reference Image for Comparison
Below is a textbook CT showing the identical pattern — acute hyperdense lesion in the right putamen with surrounding hypodense edema:
Differential Diagnosis
| Diagnosis | Likelihood | Comment |
|---|---|---|
| Hypertensive putaminal ICH | Most likely | Classic location + age + hyperdense lesion |
| Hemorrhagic transformation of ischemic stroke | Less likely | Would expect wedge-shaped hypodensity first |
| AVM rupture | Possible | Younger patients; MRI/angiography needed |
| Cavernous malformation bleed | Possible | Usually smaller; "popcorn" appearance on MRI |
| Hemorrhagic tumor | Less likely | Would expect ring enhancement + surrounding edema |
Clinical Correlation
Typical presentation:
- Sudden-onset contralateral hemiplegia (left-sided weakness given right putaminal bleed)
- Hemisensory loss
- Possible dysarthria
- Headache, nausea/vomiting
Urgent management steps:
- Neurosurgical consultation
- Blood pressure control (target SBP <140 mmHg per AHA guidelines)
- Reverse any anticoagulation if applicable
- Serial neurological assessment and repeat CT if deterioration
- Consider surgical evacuation if hematoma volume >30 mL with deterioration
