“…On the other hand, MRI consistently identifies these lesions on both T1- and T2-weighted imaging. T1-weighted images display low signal intensity, and T2-weighted images show high intensity [5, 10, 13]. Hirano et al, also reported that MRI was especially useful for the diagnosis and peripheral hyperintense rim with central low intensity on enhanced T1 images of MRI [14].…”

Objectives. Clinical records of 27 patients with extracranial head and neck schwannoma were retrospectively reviewed. Methods. Ultrasonography (US) was performed in all cases. Seven patients underwent CT. Twenty-five patients underwent MRI. Fine needle aspiration cytology (FNAC) was performed for 12 of the 27 patients. Clinical history, surgical data, and postoperative morbidity were analyzed. Results. The images of US showed a well-defined, hypoechoic, primarily homogeneous solid mass. At CT, only one of 7 cases (14%) was able to suggest the diagnosis of schwannoma. At MRI, twenty of 25 cases (80%) suggested the diagnosis of schwannoma. Only three of 12 cases (25%) displayed a specific diagnosis of schwannoma rendered on FNAC. The distribution of 27 nerves of origin was 10 (37%) vagus nerves, 6 (22%) sympathetic trunks, 5 (19%) cervical plexuses, 3 (11%) brachial plexuses, 2 (7%) hypoglossal nerves, and 1 (4%) accessory nerve. Complete tumor resection was performed in 11 patients, and intracapsular enucleation of the tumor was performed in 16 patients. The rate of nerve palsy was 100 (11/11) and 31% (5/16). Conclusions. MRI is sensitive and specific in the diagnosis of schwannoma. Intracapsular enucleation was an effective and feasible method for preserving the neurological functions.

“…This is because the preferred treatment for the unicentric variety of this disease is surgical extirpation alone [4,7,22]. However, recognizing the true etiology of the parapharyngeal space mass was important when managing post-operative expectations, especially because of the classic relationship between cervical sympathetic schwannoma excision and Horner's syndrome [23,24].…”

Castleman disease is most commonly found in the mediastinum, while the head and neck is the second most common location. The disease exists in a unicentric and multicentric variety and is usually successfully treated with surgical resection alone. Early identification is important for treatment planning. Castleman disease has been reported to mimic other disease processes, however there has been only one report of the disease mimicking a nerve sheath tumor in the parapharyngeal space. Here we report the second case of Castleman disease mimicking a schwannoma in the parapharyngeal space.

“…The ultrasonography equipment used in the study was either an HD7 Philips Ultrasound system (Philips Healthcare, Bothell, Washington) or an HS 70A (Samsung Medison, Seoul, South Korea); each was equipped with a high-frequency linear transducer (3)(4)(5)(6)(7)(8)(9)(10)(11)(12).…”

“…2 Currently, the primary preoperative diagnostic tool for head and neck mass lesions is fine-needle aspiration cytology (FNAC), which is commonly guided by ultrasonography (US). 1,4,8 However, although imaging modalities may provide some evidence for correct diagnosis, confirmation ultimately requires pathologic examination. [2][3][4] These limitations are attributed to several reasons, including that schwannomas usually contain both dense stroma and hypocellular Antoni B areas, and frequently undergo cystic change.…”

“…For these reasons, FNAC can be used to rule out the possibility of malignancy rather than for identifying schwannomas, and preoperative diagnosis of schwannoma largely relies on imaging studies such as CT and MRI. 1,4,8 However, although imaging modalities may provide some evidence for correct diagnosis, confirmation ultimately requires pathologic examination. 9 Recently, core-needle biopsy (CNB) has emerged and gained acceptance as a complementary method for FNAC and an alternative to open surgical biopsy in many head and neck structures, including the thyroid, salivary gland, and lymph nodes.…”

Fine‐needle aspiration cytology versus core‐needle biopsy for the diagnosis of extracranial head and neck schwannoma

et al. 2018

Background We aimed to investigate the feasibility of diagnosing head and neck schwannomas using core‐needle biopsy (CNB), and to compare this technique to fine‐needle aspiration cytology (FNAC). Methods We designed a prospective case series in which 52 FNAC and 29 CNB samples from 48 patients with head and neck schwannoma were analyzed. Patient demographics, pathological results, and complications were also evaluated. Results Of the 81 total specimens, 24/52 (46.2%) of the FNAC and 0/29 (0.0%) of the CNB samples were unsatisfactory (P < .001). Specific diagnoses of schwannoma, including “suspicious schwannoma” and “consistent with schwannoma,” were obtained from 10/52 (19.2%) of the FNAC samples and 28/29 (96.6%) of the CNB samples (P < .001). Major complications such as hematoma or permanent nerve injury did not occur in patients who underwent either method. Conclusions CNB can diagnose schwannomas with a higher accuracy than FNAC without increasing the rate of complications.
