A 43-year-old woman presented with headache of sudden onset. The CT scan revealed left parietal-occipital hemorrhage over an underlying lesion with partial herniation. The Glasgow coma score (GCS) was 15 until day four, when she presented right anisocoria and GCS 3. Osmotherapy was started, with sedation, mechanical ventilation, hyperventilation and the placement of a right subclavian catheter, followed by resolution of the anisocoria, with a bispectral index (BIS) of 40 (CT discarded repeat bleeding). A few minutes later an intracranial pressure (ICP) sensor was placed (65mmHg), the BIS dropped to 0 and transcranial Doppler ultrasound showed systolic flow with no diastolic wave (Fig. 1). Reversion was not achieved with first level measures. After discarding other causes of elevated ICP, a chest X-ray for catheter control (still pending) was obtained, revealing an iatrogenic right-side tension pneumothorax (PT). After evacuating the PT, the pupils normalized, as did middle cerebral arterial flow (Fig. 2), BIS and ICP.
