5 year old female with subdural fluid collection. Postoperative exam. Right-sided shunt ventriculostomy catheter is unchanged in position. Right frontal catheter terminating in subdural collection unchanged. There is a new right parietal catheter terminating in subdural collection. The left frontal catheter terminating in subdural collection unchanged in position.There is new air in the right subdural collection. The right subdural collection is not significantly changed in size, measuring approximately 3.9 cm and greatest thickness, previously measured 4.1 cm (series 80498, image 43).The left subdural collection with internal air is not significantly changed, measuring 1.7 cm in greatest thickness, previously measured 1.8 cm (series 80498 on image 29). No evidence of acute hemorrhage.The common lateral ventricular chamber is unchanged in morphology or size, measuring approximately 8.0 cm in maximal transverse dimension, previously measured 8.2 cm (series 8 stroke 498, image 30).There is stable displacement of cerebellar tonsils below foramen magnum by 9 mm, previously this measured 9 mm.There is persistent abnormal morphology of the brain parenchyma and sulci, consistent with severe periventricular leukomalacia and areas of porencephaly in superior frontal and right occipital lobes, as described on recent MRI and unchanged. Abnormal morphology of calvarium, with bilateral burr holes unchanged.The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1.Stable ventricular size.2.Stable size of bilateral subdural collections, with new air and new catheter in right subdural collection.3.Abnormal brain parenchyma, calvarium, and ventricular configuration; findings are unchanged and most consistent with severe periventricular leukomalacia and porencephaly, as described on recent MRI. 4.Stable inferior displacement of cerebellar tonsils, consistent with Chiari I malformation.
