“…Neurogenic tumors can be mistaken for solitary pleural fibrous tumors, chest wall tumors or other mediastinal masses (27,28). CT-guided biopsy is useful in obtaining a preoperative diagnosis however, due to the low cell count in benign tumors, malignant or benign traits are not always obvious (29,30).…”

Background/Aim: Thoracic neurogenic tumors are most frequently located in the posterior part of the mediastinum or on the chest wall, along the intercostal nerves. Schwannomas are very well tolerated for a long period, until the tumor reaches a large size and compression of the neighbouring mediastinal organs, chest wall or spine appears. The purpose of this article was to present a case of a giant right forth intercostal nerve Schwannoma, completely resected by a right antero-lateral thoracotomy. In addition, intrathoracic giant neurogenic tumors are a rarity. Case Report: The patient presented with only diminished tolerance to physical activity with no other obvious symptoms. Standard chest radiography revealed a well-defined opacity of subcostal intensity, occupying two thirds of the right hemithorax, forming a common body with the mediastinal shadow. Thoracic computed tomography (CT) identified a 21/11 cm solid mass that compresses the right lung and the right main bronchus with both a solid component and a central liquid area. Open surgery was performed in order to remove the tumor, which was 20.5/12.5/9 cm in size and weighed 1,830 g, well defined, with no invasion of the adjacent organs, having a solidfibromatous aspect as well as a central necrotic area. The origin of the tumor was confirmed from the posterolateral part of the forth intercostal nerve. Pathology examination and immunohistochemistry confirmed the diagnosis of a benign Schwannoma. Conclusion: Benign intrathoracic Schwannomas are asymptomatic for long periods and the main therapeutic option is complete surgical resection. The surgical approach, either open or video-assisted is dictated by the localisation of the tumor, local extension and most importantly the size of the neurogenic mass.

“…A giant type IV schwannoma is an intraspinal-extraspinal dumbbell-like tumor with the extraspinal component more than 2.5 cm in diameter [2]. Spinal schwannomas are mostly benign and extramedullary and rarely grow beyond 6 -8 cm in diameter without giving significant symptoms [2][3][4][5][6]. They may, however, manifest themselves in different ways.…”

“…Kara et al, 2002, reported a 45-year-old woman who presented with cough and mild sputum production and was found to have a 16 cm ancient schwannoma in her left hemithorax [8]. On the other hand, Kumar et al, 2006, reported an incidental finding of a 14 × 15 × 19 cm schwannoma in the right hemithorax of a 59-year-old woman [4]. Schwannomas, thus, can be insidious tumors that give subtle symptoms for many years before the patient decides to seek medical help [9] or discovering them by chance [10].…”

“…The vascular pedicles for the tumor blood supply were identified and carefully ligated. Histopathological examination of the operative specimens confirmed a diagnosis of schwannoma characterized by spindle cell proliferation [1–3]. The cells were S‐100 (+), and smooth muscle actin (−) (Figure 3).…”

Schwannomas, which are benign, are one of the most common intraspinal tumors, accounting for 29% of primary spinal tumors. Schwannomas have several other names, including neurinoma, neurilemmoma, and neuroma. They originate from Schwann cells, which were first described by Theodor Schwann, a German physiologist, biologist, and histologist. Here, we present a patient with a giant, thoracic, dumbbell‐shaped schwannoma. This benign tumor protruded into the subcutaneous fascial layer, compressing the pleura and the left side of the thoracic spinal cord. Additionally, some of the spinous processes and laminae of the thoracic vertebrae were missing. Most patients with this type of tumor are asymptomatic; however, up to 11.7% of patients have symptoms that depend on the size and location of the tumor. Magnetic resonance imaging can accurately determine the extent of the tumor and any intraspinal component and is thus helpful in selecting the optimal surgical procedure.
