2024年8月28日 · Nasal dermoids (or nasal dermoid sinus cysts) are the most common congenital midline nasal lesion typically presenting in early childhood.

2015年9月17日 · Although rare, these disorders are clinically important because of their potential for connection to the central nervous system. Lesions presenting as a midline nasal mass include: nasal glioma; nasal encephalocele; nasal dermoid cyst; nasal epidermoid cyst; hemangioma or lymphangioma; dacryocystocele; dacryocystitis; Treatment and prognosis

The contents are not compatible with encephalocele or nasal glioma, and the findings are most consistent with nasal dermoid cyst with a sinus tract continuing anteriorly and inferiorly through the bony nasal septum towards the cartilagenous portion of the septum.

2020年9月16日 · Nasal encephaloceles usually present at birth with symptoms of obstruction or other complications. It presents as an external swelling on the nose. The swelling is usually soft, with normal overlying skin, and increases in size on coughing/straining.

2023年2月9日 · Nasal gliomas, also known as nasal glial heterotopia, are a rare congenital lesion composed of dysplastic glial cells which have lost their intracranial connections and present as an extranasal or intranasal mass.

2024年8月12日 · A dorsal dermal sinus manifests as a small dimple or pinpoint ostium, which is often associated with an area of hyperpigmented, angiomatous skin or hypertrichosis and occurs in a midline location or more rarely in a paramedian location. Soft-tissue asymmetry and bone anomalies are common findings.

2024年9月5日 · sinus: incomplete tract. Cysts are the most common, outnumbering fistulas and sinuses ~2:1 6. Among fistulae and sinuses, the order prevalence is thought to be: external draining sinus > complete fistula > internal draining sinus 6; although some anomalies can occur in combination. The full list of branchial anomalies includes:

2024年10月27日 · intracranial dermoid: if ruptured will often have multiple droplets scattered through the subarachnoid space; usually midline. intracranial teratoma. lipomatous transformation of neoplasm: PNET, ependymoma, glioma

2024年12月7日 · Epidemiology. The estimated incidence is 0.8-4:10,000 live births 13 with a well recognized geographical variation between types; however, this has been speculated to be underestimated as many may result in elective termination, in utero demise, or stillbirth. There may be a female predilection 11.. Clinical presentation. The presentation may vary widely …

2021年1月12日 · Nasal dermoids (or nasal dermoid sinus cysts) are the most common congenital midline nasal lesion typically presenting in early childhood. Epidemiology Nasal dermoids are rare and account for only 4-12% of all dermoid cysts of the head and neck, far less common than angular dermoids 1,2.
