OBJECTIVE AND IMPORTANCE: Massive @entity548 due to @entity1756 is associated with a dismal prognosis. An intraventricular clot causing fourth @entity384 can cause compression to the brainstem similar to other posterior fossa masses such as @entity548 or @entity1188 . The presence of fourth @entity384 carries a very high risk of @entity204 within 48 hours. Neither ventricular drainage nor fibrinolytic infusion has been successful in eliminating clots of the fourth ventricle. Posterior fossa decompression and direct evacuation of the clot could have good results in relieving @entity2850 caused by the clot. CLINICAL PRESENTATION: A 45-year-old @entity1 was admitted to our intensive care unit after experiencing an @entity510 . The neurological examination at admission revealed that she was in Grade V according to the World Federation of Neurological Surgeons grading system, but brainstem reflexes were present. Computed tomographic scanning revealed a massive @entity548 , with fourth @entity384 caused by an intraventricular clot. Bilateral external ventricular drains were placed to relieve @entity428 . Cerebral angiography revealed a 1-cm basilar tip @entity439 , which was embolized with Guglielmi detachable coils (Boston Scientific, Boston, MA) during the same procedure. INTERVENTION: Given the @entity1 's poor @entity16 , it was decided that @entity2850 should be relieved. A posterior fossa decompressive craniectomy was performed immediately after coil therapy, with direct evacuation of the intraventricular clot. The @entity1 experienced a clear improvement in the level of consciousness and has achieved a good neurological result at early follow-up. CONCLUSION: Dilation of the fourth ventricle by an intraventricular clot is a sign of @entity2850 that can be relieved by posterior fossa decompression and direct clot evacuation.
