We describe a rare example of infratentorial primitive neuroectodermal tumor categorized as embryonal tumor with multilayered rosettes diagnosed on intra-operative squash smear and frozen section and discuss its key diagnostic features, pitfalls and differentials. Correct interpretation at the time of frozen section is crucial as it helps in deciding the further course of surgery. To the best of our knowledge, this is the first such report in the literature.
