case_images: Magnetic resonance imaging (MRI) revealed a well-circumscribed - 9 x 9 mm2 in size - solid mass keeping intensive contrast in the left frontobasal, subgaleal area (Figure 1(a) and (b)).
case_images: After tumour was removed completely, supraorbital nerve is seen (arrow).

case_images: Additionally, because the inferomedial part of the mass abutted on the supraorbital neurovascular bundle, it was excised together with it and caused bleeding (Figure 2).
case_images: Haematoxylin and eosin staining revealed that bundle of uniform, spindle-shaped cells were arranged in whorls.
