Justo E. Roque, Jr., appeals the district court’s dismissal of his complaint for lack of subject matter jurisdiction. “The district court must dismiss [an] action if it finds that it lacks subject matter jurisdiction.” Randall D. Wolcott, M.D., P.A. v. Sebelius, 635 F.3d 757, 762 (5th Cir. 2011) (citing Fed.R.Civ.P. 12(h)(3)). A district court’s dismissal for lack of subject matter jurisdiction is reviewed de novo. Wolcott, 635 F,3d at 762.

Although this court liberally construes pro se briefs, “even pro se litigants must brief arguments in order to preserve them.” Mapes v. Bishop, 541 F.3d 582, 584 (5th Cir. 2008) (citing Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993)); Fed. RApp. P. 28(a)(8). Roque has failed to make a coherent argument challenging the district court’s determination that it lacked subject matter jurisdiction over the action. When an appellant fails to identify any error in the district court’s analysis, it is *252 the same as if the appellant had not appealed that issue. Brinkmann v. Dallas Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Roque has abandoned any challenge to the district court’s dismissal of his complaint for lack of subject matter jurisdiction. See id. Because Ro-que’s appeal presents no legal points arguable on their merits, the appeal is DISMISSED AS FRIVOLOUS. See Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983); 5TH CIR. R. 42.2.
