Two cases of unsuspected intralabyrinthine schwannoma are reported and the literature is reviewed. The mean age of the patients was 56 years, with the most common symptoms being hearing loss, dizziness, and tinnitus. All patients demonstrated a profound sensorineural hearing loss with low discrimination scores, and recruitment was elicited in two ...

Olfactory schwannomas are very rare. For this reason they have never been diagnosed preoperatively. We report a case and describe the CT and MR imaging findings. Clinically, the young age of presentation, and radiologically the presence of bone scalloping, and the absence of both bone sclerosis and a dural tail, may help in the differential diagnosis ...

Trigeminal schwannomas are the second most common intracranial schwannoma. They may occur sporadically or in association with neurofibromatosis type 2. The vast majority are benign in nature although malignancies have been reported. They may present with a range of symptoms because of their variable locations in areas with multiple differing functional

A 58-year-old woman was admitted due to an abnormal shadow on chest X-ray, without any symptoms. Chest computed tomography showed a round mass in the anterior segment of the right upper lobe. Segmentectomy was performed and histopathological examination revealed a primary neurogenic tumor of Schwann cell origin.

Schwannomas are benign nerve-sheath tumors that arise from Schwann cells. They can present as endobronchial lesions with symptoms of obstruction and hemoptysis. We describe the first case of multiple endobronchial schwannomas at 3 different sites in a single patient. The autofluorescence ratio was

A case of retroperitoneal benign schwannoma is presented; in addition, 133 cases of retroperitoneal schwannoma reported in Japanese literature are studied. In our series 66 per cent of the cases were found to be cystic. Therefore, the cystic change may be one of the preoperative features of schwannomas, because other types of retroperitoneal tumor do ...

AbstractIntralabyrinthine schwannomas are rare tumours which present with symptomssimilar to Meniere's disease. Preoperative diagnosis is rarely possible and most are foundincidentally during labyrinthectomy for persistent vertigo. A further case of this tumouris reported together with a review of the literature.

Schwannoma is a benign tumour arising from Schwann cells of the peripheral nerve sheath; histologic predominance of degenerative findings is typical of a rare variant, the "ancient" schwannoma.(1-3) Retroperitoneal pelvic localization of these tumours is quite rare.(4,5) Even more exceptional is development in the perineal area, which we report here.(4)

Abstract Schwannoma of the penis is extremely rare. A 65‐year‐old man presented with a subcutaneous tumor of penile shaft without any other symptoms. Histopathologic examination of the excised tumor revealed benign schwannoma. No recurrence has been observed over the 6 months since the surgery.
