I now have comprehensive data to provide a thorough clinical management plan. Let me compile the full answer based on all the reports reviewed.
Case Summary
Patient: Mr. Rajendra Anjankar, 59 years, Male
Referring physician: Dr. N. Jaiswal, Suretech Hospital, Nagpur

MRI Brain (20 July 2026 - Follow-up study)
Impression - Post-op case of right cerebellar bleed:
| Finding | Detail |
|---|
| Post-operative status | Suboccipital craniectomy |
| Acute infarct | Small to medium, right peritrigonal region (DWI restriction, low ADC) |
| Lacunar infarcts | Few acute to subacute, bilateral fronto-parietal white matter |
| Cerebellar hemorrhage | Significant evacuation seen; residual hemorrhage 28×32 mm in operative bed |
| Intraventricular extension | Mild resolution (improving) |
| Ventricular system | Mild dilatation; VP shunt in situ |
| Ischemic foci | Multiple lacunar, bilateral ganglio-capsular + fronto-parietal white matter |
| White matter changes | Mild to moderate periventricular ischemic changes |
| Comparison to 16-Jul-2026 | No significant interval change |
CSF Reports (Dhruv Pathology Lab) - Three separate samples
Sample 1 - Collected 11/07/2026:
- Blood culture (aerobic + anaerobic): No growth after 5 days - Final report negative
Sample 2 - Collected 16/07/2026 (CSF - Reddish, Turbid):
- Gram stain: Few RBCs, few lymphocytes, few polymorphs; no organism seen
- AFB stain: Acid fast bacilli not seen
- Culture & Sensitivity (preliminary, 17/07/2026): No growth after overnight incubation - awaiting final
Sample 3 - Collected 21/07/2026 (CSF - Colourless, Clear):
- Gram stain: Pus cells not seen, organism not seen
- AFB stain: Acid fast bacilli not seen
- Culture & Sensitivity (preliminary, 22/07/2026): No growth after overnight incubation - awaiting final
Clinical Interpretation
This is a complex post-operative neurosurgical case with several concurrent issues:
1. Residual Cerebellar Hemorrhage (28×32 mm)
- The hematoma has been significantly evacuated surgically, but a sizeable residual remains in the operative bed
- No interval change from 16-Jul to 20-Jul suggests stabilization - this residual clot is likely organizing/resolving naturally
- Management: Conservative - serial MRI monitoring every 2-4 weeks. Re-evacuation is not indicated unless neurological deterioration occurs. Avoid anticoagulants and antiplatelet agents for now.
2. New Acute Infarct - Right Peritrigonal Region
- DWI restriction with low ADC confirms true acute ischemic infarct (not T2 shine-through)
- Mechanism likely: post-operative hypoperfusion, vasospasm near operative site, or micro-emboli
- The timing (post suboccipital craniectomy) puts this in the posterior circulation territory
- Management:
- Aspirin 75-100 mg/day (once hemorrhage stabilizes - after discussion with neurosurgeon, typically safe 2-4 weeks post-op when residual hematoma is stable)
- Strict blood pressure control - aim for systolic 130-140 mmHg (avoid hypotension which worsens ischemia, avoid hypertension which risks re-bleed)
- Statin therapy: Atorvastatin 40 mg nightly (pleiotropic + lipid-lowering benefit post-stroke)
- Rule out atrial fibrillation with ECG/Holter monitoring
- Evaluate for underlying vasculopathy (lipid profile, HbA1c, fasting glucose)
3. Multiple Lacunar Infarcts (bilateral ganglio-capsular, fronto-parietal)
- Pattern suggests small vessel disease (lacunar vasculopathy)
- Contributing factors at 59 years: hypertension, diabetes, smoking - all need aggressive secondary prevention
- Management:
- Control vascular risk factors aggressively (target BP <130/80 mmHg, HbA1c <7%, LDL <70 mg/dL)
- Aspirin + statin (as above)
- Long-term rehabilitation (physiotherapy, speech therapy if affected)
4. VP Shunt In Situ - Mild Ventricular Dilatation
- Shunt is functioning (mild dilatation only, down from the presumed worse state earlier given the intraventricular hemorrhage)
- Mild resolution of intraventricular extension is reassuring
- Management:
- Monitor for shunt malfunction: symptoms include worsening headache, drowsiness, vomiting, deteriorating GCS
- Serial CT head at intervals to monitor ventricular size
- Shunt revision if ventricular size increases or symptomatic hydrocephalus develops
- Keep CSF culture surveillance (as already being done)
5. CSF - Trend Toward Sterility
The CSF has notably cleared between the two lumbar puncture samples:
- 16-Jul: Reddish, turbid - RBCs + lymphocytes + polymorphs (inflammatory/hemorrhagic)
- 21-Jul: Colourless, clear - no pus cells, no organisms
This is a very encouraging trend. The turbid/hemorrhagic 16-Jul CSF was likely a combination of:
- Blood from the intraventricular extension of the cerebellar hemorrhage (traumatic/hemorrhagic vs. infective)
- Reactive pleocytosis post-surgery
The 21-Jul sample being clear and sterile, with AFB negative on both occasions and no bacterial growth, substantially reduces the probability of ventriculitis or meningitis.
- Management:
- Culture finals for 21-Jul CSF are still pending (preliminary at 22/07/2026) - await these before discontinuing any empirical antibiotics if currently on them
- If currently on empirical antibiotics (e.g., for post-neurosurgical meningitis prophylaxis), consider de-escalation/discontinuation pending culture finals
- Continue CSF monitoring if VP shunt is accessed again
- TB meningitis: Low probability given AFB negative ×2, CSF cleared, clinical picture - no empirical ATT indicated unless CSF biochemistry (protein, glucose, cell count) was abnormal (not reported here - if available, review)
- Fungal meningitis: Consider India ink stain/cryptococcal antigen if immune status is compromised
Immediate Priority Action List
| Priority | Action |
|---|
| Urgent | Await CSF culture final report (21-Jul sample, due ~5 days from collection) |
| Urgent | ECG + Holter to exclude AF as embolic source for new infarct |
| Urgent | Fasting lipid profile, HbA1c, fasting glucose, renal function |
| Neurosurgery review | Assessment of residual 28×32 mm hematoma - surgical vs. conservative |
| Within 48h | Strict BP monitoring and control (target 130-140 systolic in acute phase) |
| Medication | Aspirin timing decision (discuss with neurosurgeon re: residual bleed) |
| Medication | Start/continue statin therapy |
| Rehabilitation | Physiotherapy, occupational therapy - early mobilization |
| Follow-up MRI | Repeat in 2-4 weeks to assess residual hematoma resolution and infarct evolution |
Key Concerns to Watch For
- Shunt malfunction - any worsening of consciousness level, headache, vomiting
- Re-bleeding - sudden neurological deterioration, new focal deficits
- Infarct expansion - worsening of the right peritrigonal infarct into middle cerebral territory
- Post-neurosurgical meningitis - fever, meningismus, CSF pleocytosis on culture (less likely now given clear 21-Jul CSF, but finals still pending)
- Vasospasm - particularly if subarachnoid blood was present (check for this clinically)
Note: The CSF culture finals from 21-Jul 2026 are still preliminary as of today (22-Jul). Do not finalize antibiotic decisions until these results are available. The overall trajectory - clearing CSF, no organisms on any stain, stable MRI - is reassuring, but this remains a high-risk post-neurosurgical patient requiring close multi-disciplinary monitoring (neurosurgery, neurology, infectious disease if needed).
