Introduction: Inverted papilloma is a locally-aggressive benign neoplasm of the paranasal sinuses with a high potential for recurrence and malignancy. Intracranial extension is infrequent, and dural penetration even more so, typically associated with recurrence of the disease or its degeneration into squamous cell carcinoma. Clinical Case: A 32-year-old female patient consulted us for an exophytic lesion in her right nostril and exophthalmos, associated with headache, anosmia and dysgeusia...

Hemangiopericytomas (HPCs) are uncommon vascular tumors originating from extracapillary cells called pericytes, and rarely occur in the nose or paranasal sinuses. We treated a 57-year-old man with nasal HPC who presented with nasal obstruction and hemorrhage. Nasal endoscopy showed a readily bleeding mass between the right nasal septum and inferior turbinate. Enhanced CT revealed a heterogeneous mass lesion with an enhancement effect that filled the right nasal cavity. A biopsy specimen was proved to exhibit a HPC histopathology...

A schwannoma is a benign tumor arising from Schwann cells present in the nerve sheath of myelinated nerves.It is rarely seen in the nose and paranasal sinuses, and it very rarely originates from the nasal septum. A 40-year-old female presented to our outpatient department with a gradual onset, progressive, left nasal obstruction since the last 4 years. On performing a local examination, a soft tissue mass occupying the left nasal cavity was seen. Surgery via the external approach was performed; the mass was found to arise from the nasal septum and was totally excised...

Background: Osteosarcomas of head and neck region have unique biology and exhibit a clinical behavior and natural history that is distinct from osteosarcomas of the trunk and extremities. Our understanding of this malignant bone tumor is largely based on data from single institutions or compiled from registries, and hence the clinical practice guidelines seem confusing and conflicting. Aims and Objectives: To analyze the demographic profile, disease characteristics and survival outcomes of osteosarcoma of head and neck region...

Even if gossypibomas are extremely rare in the Oro-Maxillofacial region, they should be evoked in bizarre tumors when repeated histology tests are not contributive, especially in patients with a history of dento-sinusal surgery. As it is recommended in general surgery, gauzes should be carefully counted when used in dentistry.

BACKGROUND: Ossifying fibroma is a rare benign fibro-osseous lesion seen in the bones of the head and neck area. It is mostly found in the mandible followed by the maxilla and rarely in the paranasal sinuses along with the orbit and skull bones. CASE PRESENTATION: A 30-year-old male patient presented with headache and incidental finding of a right ethmoidal sinus ossifying fibroma by paranasal-sinuses CT scan and MRI of the face. A flexible fiber-optic nasal endoscopy examination revealed a right side fullness...

OBJECT: Skull base meningiomas carry a non-negligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (WHO grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

Glomangiopericytoma, also referred to as a hemangiopericytoma-like tumor or sinonasal type hemangiopericytoma, is a rare tumor of the nasal cavity and paranasal sinus that has never been reported in the spinal cord. Here, we report a case of a 47-year-old man who developed glomangiopericytoma in the thoracic spine. This lesion showed a heterogeneous high signal intensity compared to the spinal cord on a T2-weighted image and an easily enhanced isointense signal on a T1-weighted image.

Osteomas are slow-growing, benign bony tumors. Most are asymptomatic. Paranasal sinus osteoma in the pediatric population is rare; hence, there are few reports of symptomatic osteomas. The authors report the case of a giant ethmoid sinus osteoma in an 11-year-old girl who presented with diplopia and proptosis. Total excision and reconstruction of the medial orbital wall were performed via a coronal approach. The postoperative period was uneventful, the child's vision improved, and a good cosmetic result was obtained...

Solitary fibrous tumors (SFTs) are well recognized in the head and neck region, but rarely arise in the sinonasal tract (SNT). Six primary SNT SFTs were identified in the files of Southern California Permanente Medical Group between 2006 and 2017. The patients included five males and one female ranging in age from 33 to 72 years (mean 52 years), most of whom presented clinically with nasal obstruction. Three tumors involved the nasal cavity alone, one involved the paranasal sinuses, and two involved both the nasal cavity and paranasal sinuses...

BACKGROUND AND PURPOSE: CNS Aspergillosis is very rare and difficult to diagnose clinically and on imaging. Our objective was to elucidate distinct neuroimaging pattern of CNS aspergillosis in the immunocompetent population that helps to differentiate from other differential diagnosis. METHODS: Retrospective analysis of brain imaging findings was performed in eight proven cases of central nervous system aspergillosis in immunocompetent patients. Immunocompetent status was screened with clinical and radiological information...

Aneurysmal bone cysts (ABCs) mostly occur in the metaphysis of long bones. Primary paranasal ABCs are extremely rare and most reported cases reveal typical histopathological features including cystic space with fibrous septa and hemorrhage. Solid variant ABCs or solid ABCs lacking cyst formation may be histologically indistinguishable from giant cell reparative granulomas (GCRGs), giant cell tumor of bone (GCTB), and brown tumor. Here we report the case of a 24-year-old female with a paranasal mass diagnosed as USP6-rearranged solid ABC, mimicking GCRG, GCTB and brown tumor...

Hemangiomas are benign tumors originating from the skin, mucosa, muscle, gland, and vascular tissue in the bone. Although it is common in the head and neck region, it is rarely seen in the nasal cavity and paranasal sinuses. Histologically capillary, cavernous, and mixed types are present, the most common is cavernous-type hemangioma. Cavernous hemangiomas in the nasal cavity, generally originated from the lateral nasal wall, cause symptoms as nasal obstruction and epistaxis. In the author's patient, cavernous hemangioma was originated from the nasal septum, where rarely seen...

Malignancies of the nasal cavity and paranasal sinuses account for 1% of all malignancies and 3% of malignancies of the upper aerodigestive tract. In the sinonasal tract, nearly half of all malignancies arise in the nasal cavity, whereas most of the remaining malignancies arise in the maxillary or ethmoid sinus. Squamous cell carcinoma is the most common histological subtype of malignant tumors occurring in this area, followed by other epithelial carcinomas, lymphomas, and malignant soft tissue tumors. Although many of these tumors present with nonspecific symptoms, each tumor exhibits characteristic imaging features...

Ming-Jie Wang, Julia E Noel
Objective: Sinonasal inverted papilloma (IP) is a benign and uncommon tumor of the nasal cavity and paranasal sinuses with a tendency for recurrence and even malignant transformation. Though the morphology and clinical behavior of this lesion has been well described, its etiology remains controversial. Methods: Computerized searches were performed in PubMed, Scopus, and Google scholar through May 2015. In this review, etiologic factors including human papilloma virus (HPV), Epstein-Barr virus (EBV), cell cycle related proteins and angiogenic factors, occupational and environmental exposures, and chronic inflammation, will be discussed...
