Abstract We present the case of an 18-yr-old female with 4 mo of progressive vision loss in the left eye. She underwent a computed tomography (CT) and magnetic resonance imaging (MRI), which revealed a large mass in the sphenoid sinus, sella, and anterior cranial fossa. This mass was T1 isointense, with heterogenous enhancement noted on T1 with gadolinium sequences. The mass was found to have calcifications and cystic portions on T2-weighted MRI scans and CT-based imaging. She underwent an endonasal endoscopic approach for resection of the mass. The tumor was found to be bloody, with islands of bone nests within the dura mater of the anterior cranial fossa. The patient improved postoperatively. The pathological diagnosis was found to be the psammomatoid variant of juvenile active ossifying fibroma (JAOF). We present the neuroimaging, anatomic nuances,1 and operative techniques used in this case. We also review the disease background of this rare lesion of the anterior skull base.2-4  The patient gave informed consent for the procedure and verbal consent for the publication of this article.

<b><i>Introduction:</i></b> Nasal chondromesenchymal tumors (NCMT) are rare benign neoplasms that usually present in children &#x3c;1 year of age. They can display rapid growth and significant local bony remodeling that can mimic a malignant process. Of the ∼50 published cases to date, few have documented the need for neurosurgical intervention. We herein report a NCMT in an infant treated with a staged cranial and transnasal approach, as well as summarize the available literature on this pathology. <b><i>Case Report:</i></b> A newborn male with a compromised airway was noted to have a large sinonasal lesion. After stabilization, MRI demonstrated a 4-cm enhancing mass with diffuse sinus involvement and significant extension into the anterior cranial fossa, with displacement of the optic apparatus and hypothalamic pituitary axis. After an initial biopsy, the patient underwent a bifrontal craniofacial approach at 2 months of age, followed by a second-stage transnasal endoscopic approach at 15 months which resulted in a complete resection. There were no neurosurgical complications. Pathology was consistent with a NCMT. <b><i>Discussion:</i></b> Although rare, neurosurgical involvement is critical for the treatment of NCMTs with intracranial extension. Staged cranial and endonasal endoscopic approaches may be needed for complete resection of such lesions.

ABSTRACT Transarterial embolization (TAE) is a useful option for anterior cranial fossa–dural arteriovenous fistula (ACF–dAVF) as endovascular devices have progressed. Liquid agents are usually injected via a microcatheter positioned just proximal to the shunt pouch beyond the ophthalmic artery; however, high blood flow from the internal maxillary artery (IMA) often impedes penetration of embolic materials into the shunt pouch. Therefore, reducing blood flow from the IMA before embolization can increase the success rate. In the present case, to reduce blood flow from branches of the IMA, we inserted surgical gauze infiltrated with xylocaine and epinephrine into bilateral nasal cavities. Using this method, we achieved curative TAE with minimal damage to the nasal mucosa. Transnasal flow reduction is an easy, effective and minimally invasive method. This method should be considered in the endovascular treatment of ACF–dAVF, especially in patients with high blood flow from theIMA.
