Chordomas are primary low grade malignant tumors of bone that usually arise within both ends of axial skeleton. The Notochord is a midline, ectoderm-derived structure that defines the phylum of chordates. Chordomas may pose difficult diagnostic challenges when encountered in secondary locations, such as lungs or other parenchymatous organs. We report the cytologic findings of a metastatic chordoma sampled through CT-scan guided fine needle aspiration (FNA) of lower lobe lung nodule in a 54-year-old man diagnosed with recurrent chordoma involving the lumber spine and paraspinal region.

“…The extraspinal component of the dumbbell-shaped tumor included paraspinal soft tissue in 11 (78.6%) cases, including 1 case involving the soft tissue of the carotid triangle. 15 Other cases involved the pulmonary apex, 17 and the patient in our case had a large mass in the retropharyngeal space.…”

Retropharyngeal chordoma extending to the spinal cord, mimicking a neurogenic tumor: a case report and literature review

Chordomas are rare, locally aggressive bone malignancies with poor prognoses. However, those with minimal or no bone involvement are more easily resectable because of their well-delineated margins and thus have better prognoses. Such extraosseous chordomas of the spine are localized both intradurally and extradurally. Only a few case reports have focused on extraosseous, extradural spinal chordomas. Radiologically, this type of chordoma has a dumbbell shape; however, dumbbell-shaped spinal tumors are traditionally thought to be neurogenic tumors (i.e., schwannomas or neurofibromas). We herein report a unique case involving a woman with a dumbbell-shaped extraosseous chordoma protruding predominantly into the retropharyngeal space. A 44-year-old woman presented for evaluation of a left submandibular mass. A T2-hyperintense, gadolinium-enhancing mass was found in her cervical spinal canal, protruding through the C2/3 neural foramen into the retropharyngeal space with minimal vertebral involvement. The initial diagnosis was a neurogenic tumor, most likely a schwannoma. After subtotal removal, the pathologic diagnosis was a chordoma. Because chordomas and schwannomas have significantly different prognoses, caution is warranted when a dumbbell-shaped tumor is identified in the spine with minimal or no vertebral deterioration on radiology. This report also provides the first thorough review of extraosseous dumbbell-shaped intraspinal–extraspinal chordomas.

“…Spinal chordomas typically occur in the cervical (71.4%), followed by thoracic (14.3%), lumbar (7.1%), and sacral (7.1%) levels. [ 1 , 3 ] A review of 14 dumbbell-shaped spinal chordomas revealed that only two were located in the thoracic spine as in the case we presented [ Table 1 ]. Typically on MR scans, spinal chordomas appear isointense on T1 weighted images, hyperintense on T2 studies ( i.e .…”

Background: Epidural dumbbell-shaped chordomas are localized slow growing, and malignant/aggressive neoplasms. Here, we present a 62-year-old male with a T3-T4 dumbbell-shaped chordoma and reviewed the appropriate literature. Case Description: A 62-year-old male presented with a three-month history of thoracic pain. When the thoracolumbar magnetic resonance (MR) showed a T3-T4 dumbbell-shaped intracanalicular/extradural tumor, he underwent tumor removal. After the histological examination proved the lesion was a spinal chordoma, he underwent a secondary radical transthoracic tumor resection. Postoperatively, the patient was able to walk without assistance, and at 6-month follow-up, was neurologically intact with only residual paresthesias. Conclusion: Malignant spinal chordomas may mimic benign neurinomas on MR scans. Here, biopsy of the lesion to confirm the diagnosis of chordoma was critical and directed subsequent definitive transthoracic tumor resection.
