Abstract
Abstract
Background
Amyloidoma is a rare clinical entity characterized by the focal aggregation of amyloid protein within the body, void of systemic involvement. To our knowledge, there have only been 26 reports of cervical amyloidoma to date. Amyloid light chain and beta-2-microglobulin are the most common types, with only three previous reports of transthyretin (ATTR) Amyloidoma.
Case presentation
We report a case of a 71-year-old male who presented with worsening strength and coordination of his upper extremities, right upper-leg pain, unsteady gait, and a reduced range of motion of his neck in all planes. Magnetic resonance imaging revealed a solitary mass compressing the spinal cord at C1-C2. Treatment consisted of cervical decompression and stabilization. Pathological examination confirmed solitary amyloid deposition of ATTR. Postoperative neurological assessment revealed improved balance, gait, hand function, and grip strength. Investigational imaging was ordered 8 months postoperatively revealing no evidence of systemic involvement, confirming the diagnosis of cervical ATTR amyloidoma. A discussion is provided surrounding the published literature of ATTR amyloidoma with description of the typical presentation, management, and outcomes of this rare pathology.
Conclusion
Previous cases and studies indicate clinical signs such as ligamentum of flavum hypertrophy and carpal tunnel syndrome may precede focal ATTR spinal disposition. Outcomes for amyloidoma are generally favourable, as tumour resection prevents irreversible deficits. Patients have a low rate of recurrence with an overall excellent prognosis following resection and stabilization.

Abstract
BACKGROUND Solitary spinal amyloidoma (SSA) is a rare and poorly characterized disease. There are few cases described, and the knowledge of this neoplasm is limited. A more accurate description of demographics, clinical findings, and outcomes may be useful for a better understanding of this pathology, as well as therapeutic intervention, adding value to the research of localized amyloidosis. METHODS A systematic search was carried out from when registries began until February 2020. We also include a case diagnosed and treated in our department. Descriptive statistics were used to evaluate data, demographics, clinical findings, diagnostic modalities, therapeutics, and finally neurologic outcomes. The Kaplan-Meier method was used to assess overall survival and progression-free survival. RESULTS The final cohort comprises 35 patients. The mean age at diagnosis was 61.97 years, and 68.60% of the patients were male. SSA developed more frequently in the thoracic spine (48.60%), followed by the cervical spine (17.10%). Intradural lesions were rare, and the average neoplastic score for spinal instability was 9.5 points. The most common symptoms were impaired motor function (74.29%) and axial back pain (65.70%). After surgery, neurologic recovery was reported in 82.90% of cases. Mean progression-free survival and mean overall survival were 47.26 and 156.66 months. CONCLUSIONS SSA is a rare subgroup of localized amyloidosis, usually being diagnosed in male patients between the sixth and eighth decades. The gold standard treatment seems to be surgical resection. SSA patients have excellent long-term survival and a low rate of local recurrence.

Abstract
Of the myriad of variants of amyloidoses where abnormally folded proteins damage native tissue, primary cervical spine amyloidoma represents one of the rarest forms. Since clinical presentations and imaging findings appear similar to other pathologies, including abscesses, metastatic lesions, and inflammatory lesions, a definitive diagnosis requires a biopsy with specific immunohistochemical stains. We present the first known case of primary cervical amyloid light-chain (AL)-κ subtype amyloidoma and compare the clinical presentations, imaging findings, treatment options, and immunohistochemical subtypes of primary, hemodialysis, and multiple myeloma cervical amyloidomas. Our case is of a 58-year-old man who developed neck pain radiating to the left arm with bilateral upper extremity weakness over several months. Magnetic resonance imaging revealed a circumferential C1-C2 mass extending into the neural foramina inducing severe mass effect. The patient underwent C2 laminectomy and resection of the lesion which was discovered during surgery to be completely epidural. Postoperatively, his pain and weakness improved. A complete work-up was negative for systemic amyloidosis or inflammatory conditions. In the setting of a long clinical history of hemodialysis, this patient required specific staining and laboratory testing to correctly diagnose his primary cervical AL-κ subtype amyloidoma. Cervical amyloidomas comprise a very small minority of amyloid pathology with an exceptional prognosis following successful surgical resection and stabilization. It is recommended these patients undergo surgical resection with appropriate characterization and a complete work-up to rule out systemic disease.

Abstract
BACKGROUND Retro-odontoid pseudotumor (RP) can be caused by several diseases, especially rheumatoid arthritis, and is usually associated with the presence of atlantoaxial instability. On the other hand, a different group of patients have been identified in whom RP is observed without radiologic findings of atlantoaxial instability. The pathophysiology, clinical characteristics, and prognosis of this latter group of patients are not well described in the literature. METHODS A PubMed and Scopus search adhering to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed to include studies reporting patients with RP without radiologic instability (RPWRI). The data gathered from this review were analyzed to characterize RPWRI. RESULTS The search yielded 36 articles with a total of 62 patients. All studies were case reports and small case series. Different characteristics of RPWRI are described, including causes, pathophysiology, and treatment. CONCLUSIONS The results of this review show that RPWRI has different causes such as hypermobility, deposition of substances, and perhaps disc herniation. Depending on the cause of RPWRI, the pathophysiologic mechanism is different. Treatment should be tailored based on the primary cause of RP and the degree of compression of the cervicomedullary junction. Different degrees of improvement are usually observed after surgical treatment in these patients regardless of the treatment used, but a higher rate of mass regression was observed in those patients in whom the atlantoaxial joint was stabilized.

Retroodontoid Pseudotumor Related to Development of Myelopathy Secondary to Atlantoaxial Instability on Os Odontoideum. Case Rep Radiol 2018; 2018:1658129.

Abstract
Retroodontoid pseudotumor (ROP) is a nonneoplasic lesion of unknown etiology, commonly associated with inflammatory conditions, and the term of pannus is usually used. Less frequently, ROP formation can develop with other noninflammatory entities, with atlantoaxial instability as most accepted pathophysiological mechanism for posttraumatic or degenerative ROP. As it can clinically and radiologically mimic a malignant tumor, it is paramount for the radiologist to know this entity. Magnetic resonance imaging is the modality of choice to reveal the possible severe complication of ROP in the form of a compressive myelopathy of the upper cervical cord. The purpose of the surgical treatment is the regression or complete disappearance of ROP, with posterior decompression by laminectomy and posterior C1-C2 or occipitocervical fixation. We present the case of an elderly patient with retroodontoid soft tissue mass secondary to a chronic atlantoaxial instability on os odontoideum, an extremely rare cause of ROP. The patient developed a posttraumatic cervical myelopathy related to the decompensation of this C1-C2 instability responsible for the formation of a compressive ROP. We will overview the retroodontoid pseudotumor and its differential diagnosis.

Abstract
BACKGROUND Amyloidosis encompasses a group of disorders sharing the common feature of intercellular deposition of amyloid protein by several different pathogenetic mechanisms. Primary solitary amyloidosis, or amyloidoma, is a rare subset of amyloidosis in which amyloid deposition is focal and not secondary to a systemic process or plasma cell dyscrasia. CASE DESCRIPTION This 84-year-old female presented with history of multiple syncopal episodes, dysphagia, and ataxia. Motor strength was 3+/5 in the right upper extremity. Rheumatoid factor, cyclic citrullinated peptide (CCP), and anti-nuclear antibody (ANA) were normal. Serum and urine immune-electrophoresis detected no abnormal bands. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a non-enhancing soft-tissue mass extending from the retro-clivus to C2 posteriorly, eccentric to the right with severe mass effect on the upper cervical medullary junction. Endoscopic trans-nasal debulking of the retro-clival mass was performed with occiput to C5 posterior instrumentation for spinal stabilization. CONCLUSIONS Primary solitary amyloidosis, unlike other forms of amyloidosis, has an excellent prognosis with local resection. Diagnosis requires special stains and a degree of suspicion for the disease. This is the first report to document an endoscopic trans-nasal approach for removal of a primary solitary amyloidosis of the retro-clivus. Management of vertebral amyloidoma involves aggressive local resection of the tumor when feasible and spine stabilization as the degree of tumor involvement mandates. Complete evaluation for the diagnosis of systemic amyloidosis is essential for the management and prognostication. Surgeons encountering such lesions must maintain high suspicion for this rare disease and advise pathologists accordingly to establish the correct diagnosis.

Abstract
STUDY DESIGN A retrospective study. PURPOSE To investigate the surgical outcome for hemodialysis-related upper cervical lesions. OVERVIEW OF LITERATURE Surgical outcome of lower cervical lesions in patients undergoing hemodialysis has been reported. However, surgical outcome for upper cervical lesions in hemodialysis patients is unclear. METHODS Upper cervical lesions in nine patients undergoing hemodialysis were surgically treated. Mean age at surgery was 61.6 years (range, 52-68 years), and the mean follow-up period was 45.4 months (range, 2-98 months). Patients had undergone hemodialysis for an average of 25.3 years (range, 16-40 years) at surgery. Seven patients with destructive spondyloarthropathy (DSA) of the upper cervical spine were treated with atlantoaxial or occipitocervical fixation. Two patients with retro-odontoid pseudotumors were treated with C1 posterior arch resection alone. Japanese Orthopedic Association (JOA) scores for cervical myelopathy, postoperative complications, postoperative radiography, and preoperative and postoperative occipital pain were evaluated. RESULTS Mean preoperative and postoperative JOA score was 3.7 and 8.1, respectively. The seven patients with DSA had severe preoperative occipital pain that disappeared postoperatively. Postoperative radiography showed solid bone union in DSA cases and no instability in pseudotumor cases. CONCLUSIONS Satisfactory surgical outcome was observed for hemodialysis-related upper cervical lesions.

Abstract
A 66-year-old man was admitted to our hospital with acute paraplegia. He has suffered from hypertension with renal dysfunction for 7 years. Five months before admission, hemodialysis was introduced to him because of chronic renal failure due to renal sclerosis. One week before hospitalization, he noticed dizziness, sensory disturbance below the chest, and a urinary difficulty. Two days prior to admission, he could not walk independently. Spinal MRI revealed a mass at the 7th level of the cervical spine, showing low intensity on T(1)-weighted image and surrounding hypointensity with inner mixed intensity on T(2)-weighted image. An urgent surgery removed the cervical epidural mass and the following pathological evaluation established the diagnosis of β2-microglobulin amyloidoma. Hemodialysis-related amyloidoma generally emerges after a long duration of hemodialysis, demonstrates an insidious onset of symptoms, and is very rare. The current case indicates that we need to be aware of the possibility of β2-microglobulin amyloidoma even in patients with a short history of hemodialysis with a rapid presentation.

Abstract
Localized deposition of amyloid may occur in individual organs, in the absence of systemic involvement. The reason for localized deposition is unknown, but it is hypothesized that deposits result from local synthesis of amyloid protein, rather than the deposition of light chains produced elsewhere. We identified 20 cases of localized amyloidosis at our institution between 1993 and 2003. There were 11 males and nine females in the group. The mean age at the time of diagnosis was 65.5 years. Organs involved included skin, soft tissues, oropharynx, larynx, lung, bladder, colon, conjunctiva, and lymph node. In six of nine patients typed, the amyloid light chain was lambda. In those patients where follow-up was available (mean 7.6 years), none developed systemic disease. Localized amyloidosis occurs in a variety of organ systems. Evolution into systemic amyloidosis was not seen in our series of patients, supporting the hypothesis of local production of amyloid protein in these cases.

Abstract
Abstract
OBJECTIVE AND IMPORTANCE:
We describe a patient with cauda equina compression secondary to amyloidoma to alert other clinicians to this rare cause of a compressive epidural lesion. It is the fourth published report of primary lumbar amyloidoma causing neurological compromise.
CLINICAL PRESENTATION:
A 53-year-old, previously fit salesman presented with several years history of back pain and recent weakness, especially in the left leg. He also had numbness and tingling radiating down the left leg. On examination, the left knee jerk was diminished, and both ankle jerks were absent. Power was reduced to 4/5 in ankle dorsiflexion bilaterally. A magnetic resonance imaging scan of the lumbar spine revealed an extradural mass, compressing the theca at L3–L4. This was enhancing in T1-weighted images and had low signal intensity in T2-weighted images. There was no evidence of systemic amyloidosis or development of multiple myeloma.
INTERVENTION:
L3–L4 laminectomy was performed, with removal of the epidural mass. The patient had complete resolution of sciatica and regained normal power in both lower limbs. There was no evidence of any recurrence at 1-year follow-up.
CONCLUSION:
Lumbar epidural amyloidoma is an extremely rare cause of cauda equina compression. Clinical presentation can be nonspecific, and radiologically, it can be indistinguishable from a tumor. Diagnosis is made at histological examination of a Congo red-stained section under polarized light. Complete resection of the localized epidural amyloid mass is associated with a good prognosis.

Abstract
BACKGROUND A large solitary amyloidoma in the cervical epidural space without bony connection and with minimal spinal cord compression and no myelopathy, as a first manifestation of disseminated amyloidosis in a multiple myeloma patient, has not been reported previously; this case is thereby distinct from the seven prior reports in the world literature, of a solitary amyloidoma of the cervical spine. CASE DESCRIPTION A 72-year-old male, recently diagnosed with multiple myeloma, presented with a neuropathy that prompted a screening MRI of the cervical spine. This disclosed a large mass in the upper cervical epidural area felt to pose a high morbidity/mortality risk, leading to successful surgical removal of the amyloidoma mass. This then led to further testing that showed previously unsuspected widespread amyloidosis, which was subclinical up to that time. CONCLUSIONS In patients with a newly discovered amyloidoma, whether or not in the setting of known multiple myeloma, further evaluation should be done to detect the presence of amyloidosis. If the mass is discovered de novo, then an investigation should be carried out to determine if multiple myeloma, as well as amyloidosis, is present.

Abstract
BACKGROUND Localized primary amyloidosis is a disease characterized by a single tumor and localized amyloid deposit (amyloidoma) with no evidence of generalized amyloidosis. The occurrence of an amyloidoma in the spine is rare and only three cases affecting the axis have been previously reported. We describe the case of a 79-year-old woman presenting with a mass involving the odontoid process, responsible for an acute tetraparesia. Diagnosis of local primary amyloidosis was made after surgical excision. RESULTS Despite the critical presentation, outcome was excellent after total excision of the mass. This case can be classified as a primary localized amyloidoma. The patient did not exhibit any infection, tumor or inflammatory disease, and continued investigations failed to demonstrate other amyloid deposit after one-year follow-up. CONCLUSIONS Amyloidoma must be discussed in presence of a tumor-like mass of the odontoid process and may be responsible, as in our case, for spinal cord compression.
