Fig. 2From: Ecthyma gangrenosum due to Pseudomonas aeruginosa sepsis as initial manifestation of X-linked agammaglobulinemia: a case reportSerial CT and MRI images showing changes in the brain. a Day 19 of admission: Lateralcranial CT showing diffuse brain edema, hypodensity of the brain parenchyma, and subdural effusion in the bilateral frontal area (red arrow). b Day 25 of admission (one day before Ommaya reservoir implantation): Lateral T2-weighted MRI showing enlarged lateral ventricles and hydrops with peripheral white matter edema. c Day 27 of admission (one day after Ommaya reservoir implantation): Lateral cranial CT showing the drainage tube in the anterior horn of the left lateral ventricle. d Day 70 of admission (one day before ventriculoperitoneal shunt): Lateral T2-weighted MRI showing hydrocephalus in the ventricles was not obviously aggravated. e Day 72 of admission (one day after ventriculoperitoneal shunt): Lateral cranial CT showing the drainage tube in the lateral ventricle. e 20 months after discharge: Lateral T2-weighted MRI showing less hydrocephalus and improved interstitial cerebral edemaBack to article page
