Treatment of olfactory neuroblastoma: a new approach (original) (raw)
2014, Acta Neurologica Belgica
A 24-year-old male presented with a 6-month history of progressive left nasal obstruction, hypoanosmia, and discrete enophthalmos. As well, hypertension is present for years and peeling hands of palmar side 2-3 times a year during the winter months. Computed tomography and magnetic resonance imaging of the head showed an expansive mass in the left maxillary sinus of maximum oblique diameter 47 mm, extending into the nasal cavity ). There was a partial dehiscence of the medial wall of the left maxillary sinus. Magnetic resonance angiography indicated a slightly higher caliber of maxillary artery on the left side and cervical artery angiography identified visible signs of pathological vascularization of the tumor mass, which comes from branches of the left maxillary artery and ophthalmic artery ). According to MRI examination, structure of tumor mass was nonhomogeneous, with numerous flow-voids that indicate the good vascularization. Intrusion of the mass through expanded sinus antrum was present in middle meatus. After application of contrast, intensive and easily nonhomogeneous staining was displayed.
