acoustic neuromas (an) are schwann cell-derived tumors that commonly arise from the vestibular portion of the eighth cranial nerve also known as vestibular schwannoma(vs) causes unilateral hearing loss, tinnitus, vertigo and unsteadiness. in many cases, the tumor size may remain unchanged for many years following diagnosis, which is typically made by mri. in the majority of cases the tumor is s...

OBJECTIVE To evaluate the contribution of ultrasonography in the diagnosis of neurilemmoma and to establish if a round or round-like shape adds useful information for ultrasonographic diagnosis. METHODS Archives of ultrasound findings in 203 patients (127 males and 76 females, aged 14 -72 years old, mean 32.1 +/- 25.8) with limb mass were reviewed. The maximal and minimal diameter of the lesi...

Neurilemmomas are relatively uncommon, slowly growing tumors which originate from Schwann cells. Intrathoracic neurilemmomas often occur in the chest wall and posterior mediastinum, but endobronchial neurilemmomas are exceedingly rare. These tumors in trachea or bronchus are usually detected by radiologic examinations, mostly computed tomography scan of chest. An 88-year-old man was admitted fo...

Neurilemmomas are benign tumors which originate from Schwann cells. They rarely occur in the trachea or bronchus. We encountered two cases of endobronchial neurilemmoma and in this context, reviewed 48 cases previously reported in Japan. Neurilemmomas can occur in all regions of the bronchial tree and they often progress into both intraluminal and extraluminal spaces. Incomplete resection resul...

the vestibular system is important for the development of normal movement reactions, motion tolerance, and motor control for postural alignment, balance, and vision. a vestibular system that is damaged by disease or injury in childhood can have a major impact on a child's development. in addition, the emergence of vestibular lesions may also lead to cognitive deficits, including attention defic...

Neurilemmomas are well-encapsulated, benign, slow-growing tumors originating from Schwann cells of the nerve sheath surrounding cranial, peripheral, or autonomic nerves. Intraoral neurilemmomas are relatively rare and have a wide variety of morphologic and radiologic features. This makes differential diagnosis difficult, and only histopathological features can lead to a definitive neurilemmoma ...

Most nerve tumors (benign and malignant) do not arise from the nerves per se, but from the supporting cells; tumors arising from the cells of Schwann are termed schwannoma or neurilemmoma-benign or malignant. Surgical extirpation is the most effective treatment for these tumors. Radiation therapy can offer significant palliation and prolongation of life, but no cures have been observed. Benign ...
