Narrative:

While flying the RNAV (GPS) runway 08 approach at puerto plata; dominican republic; we had just crossed kelso at 3000 ft MSL. As soon as the aircraft began to descend; we received at single aural warning 'terrain; terrain; pull up.' no terrain depiction appeared on the flight display. It may have been a spurious warning or more seriously; a map shift. Flight conditions were IMC at night; so we honored the warning and climbed to ensure terrain clearance for that sector. We flew the approach/missed approach track into VMC conditions approximately 4.5 miles from the field; intercepted the published visual approach procedure; and landed.
