Background: Air-pouch balloon-assisted probes have proven to be both simple and reliable tools for intracranial pressure (ICP) monitoring. However, we experienced reproducible falsely high ICP measurement when the probe was inserted in intracerebral hematoma cavity. Thus, aim of experimental translational study analyze influence placement with regard measured values. 
 Methods: Two Spiegelberg 3PN-sensors were simultaneously into a closed drain system connected two separate monitors thereby allowing simultaneous measurements. This also engineered allow gradually increased controlled fashion. Once verified using identical probes, one coated blood an effort replicate within intraparenchymal hematoma. Pressures recorded control then compared across range 0-60 mmHg. In further relevance our results patient that presented large basal ganglia hemorrhage met criteria One other brain parenchyma; values from compared.
 Results: The set-up demonstrated correlation between probes. Interestingly, covered clot displayed significantly higher average value 0mmHg 50mmHg (p<0.001); at 60mmHg there no significant difference noted. Critically, this trend discordance even more pronounced clinical setting placed cavity having reported as parenchyma.
 Conclusion: Our pilot highlight potential pitfall may result secondary Such aberrant lead inappropriate interventions addresses elevated ICPs.
