Abstract: An inner case (59) for a gas turbine engine includes a case body (100; 200; 300) defining a centerline axis. The case body includes a turbine seal support (102), and an I-rod support (106) downstream of the turbine seal support. A mid-turbine frame for a gas turbine engine includes an inner case (59) having an integral case body (100; 200; 300). A method for manufacturing an inner case (59) for a turbomachine with an integral high pressure turbine seal support (102) includes fabricating a case body (100; 200; 300).
