“…Standard EUS aids in determining the exact location and origin of lesions in different esophageal layers, and the accuracy ranges from 30% to 66%[ 27 , 28 ]. Rong et al [ 29 ] reported that the diagnostic accuracy of EUS-guided fine needle aspiration for submucosal tumors is 85.2%; however, it may be misdiagnosed or missed due to insufficient sampling[ 30 ]. Therefore, the final diagnosis often requires immunohistochemical examination after surgical removal of the lesion.…”

BACKGROUND Esophageal schwannomas originating from Schwann cells are extremely rare esophageal tumors. They commonly occur in the upper and middle esophagus but less frequently in the lower esophagus. Herein, we report a rare case of a large lower esophageal schwannoma misdiagnosed as a leiomyoma. We also present a brief literature review on lower esophageal schwannomas. CASE SUMMARY A 62-year-old man presented with severe dysphagia lasting 6 mo. A barium esophagogram showed that the lower esophagus was compressed within approximately 5.5 cm. Endoscopy revealed the presence of a large submucosal protuberant lesion in the esophagus at a distance of 32-38 cm from the incisors. Endoscopic ultrasound findings demonstrated a 4.5 cm × 5.0 cm hypoechoic lesion. Chest computed tomography revealed a mass of size approximately 53 mm × 39 mm × 50 mm. Initial tests revealed features indicative of leiomyoma. After multidisciplinary discussions, the patient underwent a video-assisted thoracoscopic partial esophagectomy. Further investigation involving immunohistochemical examination confirming palisading spindle cells as positive for S100 and Sox10 led to the final diagnosis of a lower esophageal schwannoma. There was no tumor recurrence or metastasis during follow-up. CONCLUSION The final diagnosis of esophageal schwannoma requires histopathological and immunohistochemical examination. The early appropriate surgery favors a remarkable prognosis.

“…The resected tumor surface is gray-white and translucent. The histopathological features include that the tumor cells are arranged as fusiform to a fence-like structure or in a network to form a loose structure[ 30 ]. The immunohistochemical staining is currently the only reliable method for diagnosis.…”

“…Esophageal schwannoma is rare [ 34 ]. Although esophageal schwannoma has both benign and malignant features; “schwannoma” usually refers to benign tumors [ 35 ]. The rate of misdiagnosis and mistreatment is high because of the lack of awareness of the esophageal schwannoma and the need for pathological diagnosis [ 36 ].…”

“…The esophageal wall is soft, and the mucosa remains intact. The reported tumor diameter is 35–110 mm and an average of 64.8 ± 24.4 mm, in 18 cases [ 35 ]. Tumors usually display low or equal attenuation to the esophageal wall, uniform texture, occasional presence of calcified areas, and different degrees of enhancement on contrast-enhanced CT images (Fig.…”

MRI offers new opportunities for detailed visualization of the different layers of the esophageal wall, as well as early detection and accurate characterization of esophageal lesions. Staging of esophageal tumors including extramural extent of disease, and status of the adjacent organ can also be performed by MRI with higher accuracy compared to other imaging modalities including CT and esophageal endoscopy. Although MDCT appears to be the primary imaging modality that is indicated for preoperative staging of esophageal cancer to assess tumor resectability, MDCT is considered less accurate in T staging. This review aims to update radiologists about emerging imaging techniques and the imaging features of various esophageal masses, emphasizing the imaging features that differentiate between esophageal masses, demonstrating the critical role of MRI in esophageal masses. Critical relevance statement MRI features may help differentiate mucosal high-grade neoplasia from early invasive squamous cell cancer of the esophagus, also esophageal GISTs from leiomyomas, and esophageal malignant melanoma has typical MR features. Key Points MRI can accurately visualize different layers of the esophagus potentially has a role in T staging. MR may accurately delineate esophageal fistulae, especially small mediastinal fistulae. MRI features of various esophageal masses are helpful in the differentiation. Graphical Abstract
