Imaging features and differentials in surfer's myelopathy: a case report.

Surfer's myelopathy is a rare non-traumatic cause of myelopathy found in novice surfers. We present a case of a 23-year-old female who developed acute and rapidly progressive bilateral lower extremity paraplegia, paresthesia, and anesthesia, accompanied by lower back discomfort and bowel and bladder dysfunction after surfing for the first time. She had a past history of auto-resolved lower extremity weakness that could be related to anatomy variation of spinal cord vascular supply. This individual variation could have increased the risk for ischemic myelopathy after prolonged prone position with back hyperextension on the surf board. We discuss radiological findings of acute spinal cord infarct and longitudinal extensive transverse myelitis (LETM) as possible differentials in this case. The diagnosis of surfer's myelopathy relies on a first time surfing history since the clinical and radiological presentations can be similar to other entities in some cases. Thus, we highlight the importance of a full clinical report and efficient communication between referring clinicians and radiologists for a precise and early diagnosis.

Tuberculous meningitis initially manifesting as acute areflexic paraparesis: A case report.

Key Clinical Message: TBM has a very high rate of adverse sequelae if not treated immediately. Diagnosing can be challenging due to overlapping symptoms with other disease processes, and diagnostic tests are often inconclusive. Abstract: A 20-year-old man experienced progressive paraplegia and urinary retention. After extensive laboratory and imaging evaluation for tuberculous meningitis and alternative diagnoses, spinal MRI showed features suggestive of arachnoiditis. He was treated empirically with anti-tuberculosis drugs and corticosteroids. This led to significant improvement and eventual recovery.

Flank Pain as a First Symptom of a Diffuse Midline Glioma.

Diffuse midline gliomas are a new entity in the WHO Classification of Tumors of the Central Nervous System, corresponding to grade 4 gliomas. The diagnostic pathognomonic feature is the presence of a H3K27M mutation. Although mainly seen in children, cases in adults have also been reported. The symptoms are highly variable and usually dependent on the location and extent of spinal cord compression.

A New Subform? Fast-Progressing, Severe Neurological Deterioration Caused by Spinal Epidural Lipomatosis.

Spinal epidural lipomatosis (SEL) is a rare condition caused by hypertrophic growth of epidural fat. The prevalence of SEL in the Western world is approximately 1 in 40 patients and is likely to increase due to current medical and socio-economic developments. Rarely, SEL can lead to rapid severe neurological deterioration. The pathophysiology, optimal treatment, and outcome of these patients remain unclear. This study aims to widen current knowledge about this "SEL subform" and to improve its clinical management. A systematic literature review according to the PRISMA guidelines using PubMed, Scopus, Web of Science, and Cochrane Library was used to identify publications before 7 November 2021 reporting on acute/rapidly progressing, severe SEL. The final analysis comprised 12 patients with acute, severe SEL. The majority of the patients were male (9/12) and multimorbid (10/12). SEL mainly affected the thoracic part of the spinal cord (11/12), extending a median number of 7 spinal levels (range: 4-19). Surgery was the only chosen therapy (11/12), except for one critically ill patient. Regarding the outcome, half of the patients regained independence (6/11; = modified McCormick Scale ≤ II). Acute, severe SEL is a rare condition, mainly affecting multimorbid patients. The prognosis is poor in nearly 50% of the patients, even with maximum therapy. Further research is needed to stratify patients for conservative or surgical treatment.

Acute idiopathic spinal subdural hematoma: What to do in an emergency?

Acute spinal cord compression usually results from trauma, infection, or cancer. Spinal subdural hematoma is an uncommon cause of spinal cord compression that occurs after spine trauma or spinal invasive procedure, especially in context of coagulopathy. In the following reported case, an 82-year-old woman with a history of rapidly progressive paraparesis after a sudden middle back pain, with no previous trauma or coagulopathy, due to an acute spontaneous spinal subdural hematoma. In fact, the main difficulty was to determine, in an emergency situation, the right strategy to identify both the lesion and its cause to adapt therapeutics. This case not only provides an illustrative unusual condition in an emergency department but also a challenging discussion to choose the right treatment for a sudden neurological impairment. According to a literature review of the idiopathic cases of spinal subdural hematomas without coagulopathy, the clinical outcome depends on severity of neurological impairment. MRI is the main examination to perform in an emergency. Thus surgical evacuation should be performed in emergency in patients presenting with severe neurological impairment.

Surfer's myelopathy: A rare presentation in a teenage gymnast and review of the literature.

This article describes a novel setting for a rare nontraumatic spinal cord injury referred to as Surfer's myelopathy. The patient is a 16 year-old female cheerleader who presented following a gymnastics practice where she was repeatedly performing back handsprings. She demonstrated progressively worsening midthoracic back pain and evolving paraplegia and hypesthesia of the lower extremities. Magnetic resonance imaging findings were consistent with T5-T7 spinal cord ischemia at 8 h and 16 h after symptom onset. The clinical and radiologic findings for this patient are consistent with previous case reports of Surfer's myelopathy. The authors also provide a summary of the current literature describing Surfer's myelopathy, which to date includes 64 reported cases. The diagnosis of nontraumatic spinal cord injury, referred to as Surfer's myelopathy, in a gymnast highlights the importance of greater physician and patient awareness of this rare condition.

Acute paraparesis as presentation of an occult follicular thyroid carcinoma: A case report.

INTRODUCTION: Follicular thyroid carcinoma is the second most frequent type of well differentiated thyroid tumours. It is usually confined to the thyroid gland, however it can metastasize in a later stage of the disease. Signs and symptoms associated with bone metastasis are rare as first clinical manifestations. CASE REPORT: An 84-year-old female complained with acute paraparesis. Magnetic resonance imaging revealed an extensive intraosseous infiltrating lesion compatible with a bone metastasis from an occult tumour. Biopsy samples were compatible with bone metastasis from a follicular thyroid carcinoma. The patient was submitted to total thyroidectomy followed by iodine ablative therapy. DISCUSSION: Follicular thyroid carcinoma presentation with symptoms related to bone metastasis is rare. Patients with bone lesions, such as pathological fractures or compressive symptoms should be studied since they may have clinically unapparent lesions from an unknown tumour. Patients with FTC should be submitted to total thyroidectomy. Bone lesions may be addressed to improve quality of life however this decision depends on disease extent. CONCLUSION: Acute paraparesis is a rare form of presentation of thyroid carcinoma. These neoplasms must be taken into account when investigating metastasis to the bone from unknown neoplasms.

Delayed onset paraparesis complicating epidural steroid injection with underlying spinal dural arteriovenous fistula.

We report a case of a 48-year-old man with chronic back pain attributed to discogenic lumbar radiculopathy who underwent a fluoroscopy-guided L2-3 interlaminar epidural steroid injection. 4 h later, he developed acute paraparesis, sensory loss below T10 level and urinary retention. MRI of the thoracic spine revealed diffuse abnormal T2/FLAIR signal and extensive vascular flow voids. A spinal dural arteriovenous fistula was confirmed on spinal angiography. Embolization of the spinal dural arteriovenous fistula resulted in significant improvement of symptoms. We review previously reported cases and current understanding of the pathophysiology of this complication. All cases had symptom onset several hours after the procedure. There seems to be a trend toward better outcomes with earlier treatment.

Spinal intramedullary arachnoid cyst: case report and literature review.

BACKGROUND CONTEXT: Intramedullary arachnoid cysts are extremely rare; only 14 cases have been reported in the literature so far. PURPOSE: We report on the case of a 31-year-old woman who presented with back pain and progressive paraparesis secondary to a dorsal intramedullary arachnoid cyst detected on magnetic resonance imaging (MRI): the surgical planning and clinico-radiological outcome are discussed along with a review of the relevant literature. STUDY DESIGN: Case report and literature review. PATIENT SAMPLE: One patient affected by intramedullary arachnoid cyst. OUTCOME MEASURES: Magnetic resonance imaging and pathological findings from operative specimens were used to confirm the diagnosis. METHODS: A 31-year-old woman presented with a 7-year history of back pain that had worsened 3 months before admission to our department; for this reason, the patient had undergone a spinal MRI revealing the presence of a 1-cm cystic intramedullary lesion at the level T11-T12, with no contrast enhancement. After 2 months, the patient presented with a worsening of clinical symptoms complaining of severe back pain radiating to the lower extremities associated with a progressive paraparesis, urinary incontinence, and abdominal pain. Referred to our department, at the time of admission the patient was bedridden because of the impossibility of maintaining a standing position. The patient underwent a T11-T12 laminectomy with fenestration of the cyst. RESULTS: She experienced an immediate relief of pain symptoms, and by the seventh postoperative day she was able to stand without help and walk a few meters with assistance. By the sixth postoperative month, the patient had significantly improved, having gained the ability to walk alone without assistance with complete resolution of the bladder dysfunctions, with no cyst recurrence after approximately 2 years of follow-up. CONCLUSIONS: Intramedullary arachnoid cysts should be considered in the differential diagnosis for intramedullary cystic lesions. A particular consideration deserves their occurrence in asymptomatic patients, who should be adequately informed on the possible natural evolution: when symptomatic, surgical therapy should be promptly offered, considering that a postoperative complete recovery is usually observed, regardless of the surgical technique.
