We experienced a case of vestibular schwannoma and metachronous schwannoma in the colon. A 59-year-old female presented with a 1-month history of hematochezia. She had undergone suboccipital craniectomy resulting in radical subtotal resection, followed by gamma knife radiosurgery for a large left vestibular schwannoma 4 years prior to admission. On preoperative colonoscopy, a huge mass through ...

OBJECTIVES With rising quality of speech perception in cochlear implant users, the indication widens. Nowadays, cochlear implantation is reasonable even in vestibular schwannoma patients. Speech perception with a cochlear implant is in these patients as promising as in patients with sensorineural hearing loss. However, the impact of cochlear implantation on vertigo and tinnitus after removal of...

UNLABELLED INTRODUCTION Schwannomas are mostly benign tumors arising from Schwann cells of the nerve sheaths. Breast schwannomas are very rare and account for only 2.6% of cases. As far as we know this is the first reported case of breast schwannoma discovered in a patient with diffuse large B-cell lymphoma. The breast schwannoma was evaluated with positron emission tomography and it exhibit...

Schwannoma originating from the cervical vagus nerve is an extremely rare neoplasm. Vagal nerve schwannoma usually occurs between the third and fifth decades of life, it does not show sex predilection both sexes being equally affected and it most often presents as a painless, slow-growing, lateral neck mass. The treatment of choice is complete surgical excision with preservation of the neural p...

Primary malignant schwannoma of the small intestine is an extremely rare disease. We report a primary malignant intestinal schwannoma of the small bowel in a 66-year-old woman, who was admitted to the hospital because of fatigue and anaemia. On clinical examination there was a solid mass at the abdomen. Ultrasound scanning showed an abdominal tumour. Computed tomography showed a mass in the are...

A schwannoma is a tumor that develops on peripheral nerves or spinal roots. Although any part of the body can be affected, the breast is a quite unusual site for schwannomas. We report herein a case of schwannoma presenting as a breast tumor. In the current case, the tumor showed both clinically and mammographically as a well-defined breast mass. Of interest, sonographically, the well-defined m...

schwannoma is a benign encapsulated slow-growing tumor that originates from schwann cells of the peripheral nerve sheath. it usually occurs in the head and neck; however, it is rare in the oral cavity. the tongue is the most common site of intraoral schwannomas, followed by the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area. we report a rare case of schwannom...

Schwannoma, also known as neurilemmoma, is a slowly growing benign neurogenic tumor, originating from the Schwann cells of nerve sheath. Schwannoma can arise various nerves such cranial nerves, spinal autonomic and most common in head neck area. However, lingual very rare clinical findings are non-specific. Therefore, when it occurs submandibular space, difficult to differentiate them other tum...

Background: A pure intramuscular paraspinal schwannoma is extremely rare, with only few case reports in the literature. Due to low frequency, lack of specific clinical signs and symptoms difficult radiological assessment, pre-surgical workup leads a broad differential diagnosis. The aim work carried out was therefore search for evidence common schwannoma, useful diagnostic work-up, highlight po...

A 47-year-old woman was referred to our hospital for further examination of a lung tumor. CT of the chest revealed a round, well-defined 2.4-cm nodule in S2, adjacent to right superior lobe bronchus. Endobronchial ultrasonography showed a well-defined, hypoechoic tumor with echogenic capsule and posterior acoustic enhancement. Diagnosis of schwannoma was confirmed from the specimen obtained by ...
