a, b Preoperative MRI (1.5 T field strength): axial post-gadolinium T1 (a) and axial T2 (b). c-f Postoperative MRI (3 T field strength). c Axial post-gadolinium MPRAGE. d Axial T2. e Coronal post-gadolinium T1. f Coronal T2. The postoperative images reveal loss of the left frontoinsular cortex, along with a portion of the white matter, claustrum, and striatum underlying this anterior-inferior subregion of the insula.

Brain MRI revealed a 3.5 x 4 cm extra-axial mass along the anterior clinoid process of the left sphenoid wing, with uniform gadolinium enhancement, plus vasogenic edema in the adjacent brain (shown in Fig. 1).
a Change in body weight (kg) over time. b Change in body mass index (BMI) relative to the local distribution. Blue bars in this histogram represent the BMI distribution of n = 362,794 adult female patients (18-80 years) in the University of Iowa Hospitals and Clinics (UIHC) electronic medical record. Red bars represent the histogram bins containing our patient's initial postoperative BMI (38.6 kg/m2, 85th percentile) and most recent BMI (24.9 kg/m2, 25th percentile).

This 35% weight loss (-36.2 kg; -87 lbs; -13.7 kg/m2) represented a fall from the 85th to the 25th percentile among adult women in our electronic medical record (Fig. 2) and among US women her age ("Anthropometric Reference Data for Children and Adults: United States, 2015-2018," Table 4; available at cdc.gov).
