“…Various tumors may present with a dumbbell formation (e.g. chondrosarcoma, neurilemmoma, neuroblastoma [45], [46]). The differential diagnosis of intraspinal cystic lesions includes dorsal arachnoid diverticula and meningoceles and the differential diagnosis of intradural cystic lesions includes arachnoid cysts, syringomyelia and neurocysticercosis.…”

Bone involvement in human cystic echinococcosis (CE) is rare, but affects the spine in approximately 50% of cases. Despite significant advances in diagnostic imaging techniques as well as surgical and medical treatment of spinal CE, our basic understanding of the parasite's predilection for the spine remains incomplete. To fill this gap, we systematically reviewed the published literature of the last five decades to summarize and analyze the currently existing data on epidemiological and anatomical aspects of spinal CE.

A 45-year-old woman with a pre-sacral mass lesion: diagnosis and discussion

Endometriosis presenting as a pre-sacral mass lesion causing sacral foraminal expansion and S1 radiculopathy. DiscussionThe MR examination demonstrates a 6×2.5-cm pre-sacral mass lesion that is extending into and expanding the left S1 exit foramen. This mass extends into the epidural fat, displacing and partially surrounding the S1 nerve, but it did not extend distally to affect the exiting S2 or S3 nerves. The lesion shows a heterogeneous signal pattern on T1-and T2-weighted sequences with focal areas of high signal intensity on the T1-weighted sequences indicative of small areas of haemorrhage. The lesion is predominantly hyperintense to muscle on T2 weighting and following contrast medium administration, and a relatively uniform enhancement pattern is identified. Trans-sacral biopsy by an approach lateral to the exit foramen was performed to exclude recurrent rectal carcinoma. The biopsy material demonstrated endometriosis characterised by endometrial glands surrounded by endometrial stroma with strong positivity for oestrogen and progesterone. As a result, the patient was commenced on hormonal treatment and the neurological symptoms improved.

“…The degree of spinal cord compression was marked inferiorly and there was intrinsic signal change, thought to be from either oedema or venous infarction. Dumbbell tumours are more typically caused by non-neoplastic tumours, such as tuberculous spondylitis, aneurysmal bone cysts and extradural arachnoid cysts 2. Neoplastic dumbbell lesions include tumours originating in the central nervous system such as schwannomas and neurofibromas, as well as tumours arising from within the vertebrae, such as spinal metastases and solitary bone plasmacytomas 2.…”
