The kinetic energy operator with position-dependent-mass in cylindricalcoordinates is obtained. The separability of the corresponding Schr\"odingerequation is discussed within radial cylindrical mass settings. Azimuthalsymmetry is assumed and spectral signatures of various z-dependent interactionpotentials (Hermitian and non-Hermitian PT-symmetric) are reported.

Position-dependent-mass; Cylindrical coordinates, separability, exact solvability, and PT-symmetry
