“…25 Because chordomas arise from the extradural space and invade intraspinal regions, they also present as dumbbell-shaped tumors. [8][9][10][11][12][13][14][15][16][17][18] We reviewed previously reported spinal extraosseous dumbbellshaped chordomas in intraspinal and extraspinal locations that were classified as having an "extraosseous extradural" pattern, as in our case (Table 1).…”

“…7 Only 11 case series have documented the special radiologic pattern of extraosseous chordomas, which have a dumbbell appearance. [8][9][10][11][12][13][14][15][16][17][18] The representative dumbbellshaped tumors of the spine are benign neurogenic tumors, usually schwannomas. 16 Dumbbell-shaped lesions responsible for neural foramina widening include meningiomas, plasmacytomas, chordomas, infectious lesions, and cysts associated with the surrounding bone and spinal cord.…”

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.

We present an unusual case of a chordoma presenting as an extradural spinal tumour with extension through an expanded intervertebral foramen to form a large paraspinal mass. The magnetic resonance imaging appearances closely mimicked a neurofibroma; however, pre-operative biopsy confirmed the diagnosis of chordoma. This is, to our knowledge, the tenth reported case of chordoma presenting as a mass expanding the intervertebral foramen. Thus, while it is a rare form of chordoma, it can lead to a recognised radiological pitfall. Making the distinction from neurofibroma before surgery is essential, as radical dissection of chordoma is required to reduce the risk of local recurrence.
