Neuroectodermal tumour has a wide range of biological activity that ranges from an indolent course to local recurrence and rapid widespread metastasis. We describe, herewith, 2 patients with Esthesioneuroblastomas (ENB) who had varied atypical clinical presentation. The first case presented with Intracranial Pressure (ICP) headache and acute visual deterioration with radiology revealing an extra axial lesion with extension into the nasal cavity while the second case presented with nasal congestion and progressive headache of long duration. We review the unusual characteristics that may uncommonly occur in ENBs and elaborate regarding which of these must be considered when evaluating patients with this malignancy.
