A known case of right frontal tuberculoma, on treatment, had seizures, went into status and had to be intubated. Later, patient was found to have bradycardia and non reacting pupils. A CT scan was done.

CT showed swollen brain, loss of gray white differentiation, compression of CSF spaces. And most strikingly, sulcal and cisternal hyperdensity. Looks like SAH!. But it is not. Look at the dural sinuses, they are hyperdense as well. This is a case of ‘pseudo SAH’ appearance due to stagnant flow in the arteries and veins.
