The authors report a case of simultaneously occurring neurofibroma and schwannoma of the sciatic nerve and discuss the complementary aspects of MR and US. The schwannoma was well-defined and showed distal enhancement on sonographic evaluation, whereas the neurofibroma was ill-defined; both tumors were hypoechoic. T1- and T2-weighted MR images revealed similar signal characteristics of the two t...

The simultaneous occurrence of an adenocarcinoma and schwannoma is extremely rare in the stomach, and only one such case has been previously reported, which presented as two separate masses. Indeed, the collision of these tumors has never been reported. We report the case of a 61-year-old male patient who was diagnosed with the synchronous development of a schwannoma and advanced mucinous adeno...

Schwannoma is a benign peripheral nerve sheath tumor that typically involves cranial nerves of the head and neck region. Intraparenchymal occurrence of this tumor is uncommon. Even rarer in this site is the microcystic/reticular pattern of schwannoma. This histologic variant, first described in 2008, has a predilection for visceral organs. Herein, we report the first case of microcystic/reticul...

Cellular schwannoma (CS) is a variety of schwannoma with a predominantly cellular growth, normally developing in middle-aged patients. In this report, we describe a 15-month-old infant with primary cutaneous CS on the knee. Because of its histologically malignant features, CS is sometimes overdiagnosed as a malignant nerve tumor. Therefore, awareness of this variant of schwannoma is important f...

abstract the intraparenchymal schwannomas are very rare tumors with only 52 reported cases . we describe a 38 years old man with eight months history of poorly controlled seizures despite of medical therapy. on brain ct scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. on brain mri the lesion was hypointense in t1 and hyperintense in t2 with homog...

Distalization of maxillary molars with intraoral appliance is a non-extraction treatment approach for correction of Class II malocclusion that has been described as an alternative to headgear. The aim of this review article is to discuss about the various criteria that should be considered while deciding to distalize molars and a comprehensive review of commonly used intraoral molar distalizati...

Schwannoma of parotid gland in a child is rare. We report a rare case of schwannoma in parotid gland in a 10-year-old child who presented with a gradually enlarging swelling in parotid region for the last I year. Color doppler study showed increased vascularity in the lesion with venous return pattern, suggestive of a hemangioma. However, fine needle aspiration cytology showed features consiste...

First described intracochlear schwannoma was in 1917 [1], by temporal bone specimens archive. Intralabyrinthine schwannomas classified according to location of schwannoma in inner ear. For example, intracochlear, intravestibular and intravestibulocochlear schwannoma [2]. Main presenting symptom is hearing loss [3]. Tinnitus, vertigo, imbalance, and aural fullness are other symptoms. We report a...

We report a rare case of schwannoma of the brachial plexus presenting as an enlarging cystic mass. A 52-year-old woman was found to have a rapidly enlarging cystic lesion in the left pectoralis minor space. Surgical exploration finally found that the lesion was schwannoma originating from the fascicles of the brachial plexus. Partial removal of the fluid enabled us to dissect the mass without d...

OBJECTIVE To investigate the clinical usefulness of intraoral sonography-assisted resection for securing adequate deep resection margins in T1-2 tongue cancers. STUDY DESIGN Prospective clinical trial. MATERIALS AND METHODS Twenty consecutive patients with clinical T1-2 tongue cancers were enrolled and their lesions were removed by intraoral sonography-assisted resection. We then retrospect...
