Je Yeon Byeon, Hwan Jun Choi
Orbital cellulitis and abscess have been described in the literature as complication that usually occur secondary to infection in the maxillary, ethmoidal, and frontal sinuses. If left untreated, it can lead to blindness, cavernous sinus thrombosis, meningitis, or cerebral abscess. Orbital fractures are a common sequela of blunt orbital trauma, but are only rarely associated with orbital cellulitis. So, the authors present rare orbital cellulitis after orbital blow-out fracture. A 55-year-old Asian complains of severe orbital swelling and pain on the left side...

Cerebral abscess is a potentially fatal neurosurgical condition, despite improvements in technology, new antimicrobial agents and modern neurosurgical instruments and techniques. I report the case of a 64-year-old woman, affected by a right frontobasal brain abscess, compressing the homolateral frontal horn of lateral ventricle, with a second mass partially occupying the right orbital cavity. She presented also with inflammatory sinusopathy involving the right maxillary, ethmoid and frontal sinuses. After 14 d of clinical observation and antimicrobial therapy, the patient received a computed tomography scan, which showed growth of the cerebral mass, with a ring of peripheral contrast enhancement and surrounding edema...

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome often associated with fibroblast growth factor 23 (FGF23)-producing tumors such as phosphaturic mesenchymal tumor, mixed connective tissue variant (PMTMCT) affecting the bone and soft tissue. We experienced a patient with progressive bone and muscle pain due to FGF23-related TIO. Venous sampling had strongly suggested the anterior skull base as a source of FGF23, which led to the discovery of a small tumor in the ethmoid sinus extending intracranially...

INTRODUCTION: Osteomas of the paranasal sinuses are benign bone tumours that produce clinical signs depending on their size and location. In most reported cases large tumours are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumours is a huge challenge for the operator. OBJECTIVE: Determine the optimal surgical approach by analysing giant osteomas of the frontal and ethmoidal sinuses in the literature...

Paranasal sinus mucoceles are mucus-containing cystic structures with an epithelial lining that completely fills in the paranasal sinuses. Although they are benign in nature, they may result in the destruction of the surrounding bony structures over time. Clinical findings such as exophthalmia, visual impairment, and diplopia occur due to pressure of the fronto-ethmoidal mucocele on the orbita. Currently, the endoscopic intranasal approach is preferred in the treatment of paranasal sinus mucoceles due to its minimal morbidity and low recurrence rates...

BACKGROUND: Olfactory dysfunction is 1 of the hallmark symptoms of chronic rhinosinusitis (CRS). Eosinophilic inflammation has been implicated as a potential causative factor. However, prior studies have been limited by retrospective study designs, concomitant use of systemic corticosteroids, and other confounding factors. METHODS: CRS and healthy non-CRS control subjects undergoing endoscopic sinus or skull-base surgery were prospectively enrolled and completed olfactory testing utilizing the 40-item Smell Identification Test (SIT) immediately prior to surgery...

Orbital subperiosteal abscess (OSPA) secondary to paranasal sinus mucocele (PSM) is rare, and it may be misdiagnosed as PSM with orbital invasion or even as a malignant neoplasm. The present study explored the computed tomography (CT) and magnetic resonance imaging (MRI) features of OSPA. The cases of 13 patients with OSPA secondary to PSM were retrospectively reviewed. CT had been performed in 12, MRI in 7, and postcontrast MRI in 4. OSPA was revealed as a well-demarcated, spindle-shaped mass that was broad-based and located beneath the superior orbital wall (orbital roof) in 11 and at the medial wall in 2...

Common variable immunodeficiency (CVID) is a primary immunodeficiency manifesting as a reduction in the level of total immunoglobulin (Ig) G, a reduction in the level of either IgA or IgM, poor response to polysaccharide vaccine, and usually frequent infections. The association of CVID with an increased risk of malignancy, specifically lymphoma, is well known. A 63-year-old female with a past medical history significant for CVID presented with a 1-month history of dull, left eye pain with proptosis, hypoglobus, and left upper lid fullness without a discrete palpable mass...

BACKGROUND: Isolated polypoid changes of the middle turbinate were recently reported as having a high association with inhalant allergy. A more advanced manifestation of this association may present as polypoid changes of the entire central sinonasal compartment (i.e., the middle and superior turbinates, and the posterosuperior nasal septum), while the lateral sinus mucosa remains relatively normal. OBJECTIVE: To introduce and describe this newly recognized variant of chronic rhinosinusitis (CRS), termed central compartment atopic disease (CCAD)...

The complications of sinusitis are essentially secondary to ethmoidal and frontal sinusitis, occurring in patients weakened, particularly in case of immunodeficiency or anatomical defects. The gravity is due to the risk of spreading infection in intracranial tissues and orbital cavity. The diagnosis is always to discuss any symptomatology resistant to treatment and the appearance of orbital or neurological signs. The scanner and MRI contribute greatly to the orientation and diagnostic evaluation of the extent of the lesions...

Squamous Cell Carcinoma (SCC) of the cervix is a highly prevalent malignancy. Its spread and metastasis is mostly loco-regional. The occurrence of distant extra-pelvic metastases is exceedingly rare, particularly with the involvement of paranasal sinus. This case report documents an unusual presentation of a 45-year-old female diagnosed and treated for squamous cell carcinoma of cervix with metastatic deposits in the ethmoidal sinus without deposits in any intervening foci.

The nasal cavity and paranasal sinuses are covered with ciliated respiratory mucosa of ectodermal origin, known as Schneiderian epithelium, which can give rise to different types of sinonasal carcinomas. A 42-year-old woman with a history of nasal polypectomy 3 years previously presented with nasal obstruction and rhinorrhea. She was found to have a papillary mass involving the left nasal cavity, and the left maxillary and ethmoidal sinuses by radiologic examination. She underwent endonasal resection under the diagnosis of oncocytic papilloma...
