We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was...

Benign schwannoma is the most common neurogenic tumor in the mediastinum. Mediastinal benign schwannomas are most often asymptomatic and rarely accompanied by bloody pleural effusion. In the clinical analysis of 7 cases of pulmonary schwannomas, pleural effusion, and blood invasion were evident in 3 patients with malignant schwannoma. Herein, we report a rare case of giant, benign schwannoma pr...

BACKGROUND AND PURPOSE Orbital SFT is a rare tumor, often misdiagnosed as orbital schwannoma preoperatively but with different prognosis and treatment. Our aim was to evaluate MR imaging features that might distinguish orbital SFT from schwannoma. MATERIALS AND METHODS MR imaging including DCE scanning was performed in 9 patients with SFT and 22 patients with schwannoma in the orbit confirmed...

STATEMENT OF PROBLEM Intraoral scanners have been reported to have limited accuracy in edentulous areas. Large amounts of mobile tissue and the lack of obvious anatomic landmarks make it difficult to acquire a precise digital impression of an edentulous area with an intraoral scanner. PURPOSE The purpose of this in vitro study was to determine the effect of an artificial landmark on a long ed...

The aim of this study was to investigate the Turkish voicing contrast with simultaneous measurements of acoustics, EPG and intraoral pressure. We further aimed to understand the mechanisms behind the maintenance or disappearance of voicing in Turkish. According to our results, intraoral pressure rises more slowly for voiced sounds than for their voiceless counterparts. Voiced fricatives have sh...

The coexistence of schwannoma and meningioma in the same cerebellopontine angle (CPA) is uncommon. Especially, the presence of a single mixed tumour composed of demarcated or intermingled components of schwannoma and meningioma tissue is extremely rare. Such a phenomenon is mainly reported in a patient with NF2 or with history of previous irradiation. We present two cases of simultaneous occurr...

BACKGROUND Schwannoma and angiosarcoma are infrequent pathologies that have been rarely reported in the kidney. Angiosarcoma is an uncommon malignant tumor presenting a recognizable vascular differentiation. It can develop in any site but the most common locations include the skin, soft tissues, breast, bone, liver, and spleen while renal localization has been very rarely reported in the litera...

Four cases of schwannoma originating from the lower cranial nerves are presented. Case 1 is a schwannoma of the vagus nerve in the parapharyngeal space. The operation was performed by the transcervical approach. Although the tumor capsule was not dissected from the vagus nerve, hoarseness and dysphagia happened transiently after the operation. Case 2 is a schwannoma in the jugular foramen. The ...

BACKGROUND AND PURPOSE Uveal schwannoma is a rare benign neoplastic proliferation of pure Schwann cells. The purpose of this study was to describe MR imaging features of uveal schwannoma. MATERIALS AND METHODS MR images in 6 female patients with uveal schwannoma confirmed by pathologic examination were retrospectively reviewed. MR imaging was performed in all 6 patients, with postcontrast T1-...
