Lu T, Wang H, Liu Y, Qin X, Teng Y, Wang Y. Demographic and clinical data of patients with spinal epidural angiolipomas. Sci Rep 2024; 14:17473. [PMID: 39080392 PMCID: PMC11289124 DOI: 10.1038/s41598-024-67584-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 07/12/2024] [Indexed: 08/02/2024] Open
Abstract
Spinal epidural angiolipomas are rare, benign, mesenchymal tumors. It remains unclear whether spinal epidural angiolipomas are genuinely rare or merely underreported. Herein, we assessed the demographic and clinical characteristics of patients with spinal epidural angiolipoma. We collected data from patients with spinal epidural angiolipoma from three sources. First, we retrospectively analyzed data from patients diagnosed with spinal epidural angiolipoma in our hospital between January 1, 2014, and December 31, 2023. Second, we performed a literature review of studies retrieved from PubMed. Third, we retrieved detailed data of patients with spinal angiolipoma from the Surveillance, Epidemiology, and End Results (SEER) database. We conducted a descriptive analysis to investigate the demographic and clinical characteristics of patients with spinal epidural angiolipoma. At our institution, three patients were diagnosed with spinal epidural angiolipoma. Additionally, we identified 116 patients from the literature review and 15 patients from the SEER database. We reviewed the treatment history and imaging features of the three patients from our institution. The descriptive analysis of the data collected from the literature review was consistent with previous reports. For example, 63.0% of lesions were located at the thoracic level. 31.9% of these lesions involved two vertebral bodies, while 75.6% involved 2-4 vertebral bodies. The most common symptoms experienced by patients were back pain, paraparesis, and numbness in the legs. Surgery was the primary treatment option for most patients, and complete tumor resection was achieved in the majority of patients. The male:female ratio was 1:1.4, the median age at diagnosis for the patients from the literature was 49 years old, and the median follow-up was 24 months. Notably, most of the reports came from Asia and there were few reports from Africa. The findings from the SEER database indicated a male:female ratio of 2:1. The peak incidence, which is typically reported in the fifth decade of life, was not observed. We presented three cases of spinal epidural angiolipoma and supplemented our findings with a literature review and population-based analysis according to the SEER database for the United States population. We believe that our research will enhance clinicians' comprehension of this uncommon tumor.

Abstract
BACKGROUND Spinal angiolipomas (SAs) are rare, benign tumors, representing 0.0004 to 1.2% of angiolipomas, usually located at the extradural and posterior thoracic level, with multimetameric extension. METHODS A systematic literature review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The authors searched on PubMed and Scopus databases for published articles with the Mesh term "spinal angiolipoma" and pertinent associations. Language restriction to English papers was applied. The authors also reported three emblematic cases of patients who underwent surgical resection of spindle-shaped (type IA) and dumbbell-shaped (type II) SAs between 2014 and 2020. RESULTS Of the 256 retrieved articles, 33 were included in the meta-analysis. These 33 studies, together with our 3 reported cases, included a total of 60 patients, 36 females (60%) and 24 males (40%), with a mean age of 53.12 ± 12.82 years (range: 12-77 years).T5 was the most represented level (22 patients). Usually, the localization of SA was extradural, with 53 patients suffering from spindle-shaped type IA SA (88.3%) and 7 patients from dumbbell-shaped type II SA (11.6%). Almost all patients underwent laminectomy (78.3%) and presented a full recovery of motor deficits (85%). Gross total removal (GTR) was performed in 93.3% of patients. The mean follow-up was of 22.71 ± 21.45 months (range: 2-80 months). There was no documented recurrence at follow-up magnetic resonance imaging in any of the patients. CONCLUSIONS SAs are rare, benign tumors with a great vascular component that presents a favorable outcome. GTR is the gold standard treatment and usually an adjuvant therapy is not required. Even infiltrative lesions, which are more complex, can be treated successfully with a good prognosis. Dumbbell-shaped SAs must be differentiated from schwannomas and meningiomas, and require different surgical techniques, given the profuse bleeding associated with the attempt of debulking. En block resection is the key to treat these common benign tumors with acceptable blood loss.

Abstract
Angiolipoma is a rare subtype of lipoma that contains both mature adipocytes and a rich vascular component. Infiltrating spinal angiolipomas causes surgical challenges with potential on-table injuries to adjacent structures. We present a rare case of infiltrating spinal angiolipoma in a 76-year-old woman who presented with paraplegia and hydrocephalus. At the time of presentation, the patient was bedridden for 3 months due to a complete loss of motor power. Imaging examination revealed a lesion involving the T6 vertebra with compressive myelopathy. The patient underwent spinal decompression and resection of the lesion, which turned out to be an infiltrating angiolipoma by histological examination. This is a unique case because spinal angiolipoma is extremely uncommon and such lesions generally manifest without infiltration. This case report highlights the existence and importance of spinal angiolipoma as a differential diagnosis of chronic backache resulting in neurological deficits and hydrocephalus.

Abstract
Angiolipoma are benign tumors composed of mature adipocytes ad mixed with abnormal vascular elements. It reportedly accounts for 0.1–0.5% of all spinal axis tumors in adults and is extremely rare in children. This article describes a case of spinal extradural angiolipoma in a 35-year-old man, who presented with paraplegia and sphincter disorders, the MRI showed extradural spinal lesions at the level of T7 to T10, that squeezed the spinal cord. We attained total resection without any further neurological complication. The diagnosis of SEALs initially can be challenging radiologically since they may imitate other spinal lesions. The gold standard treatment modality should always be surgery, however in some cases, total resection can not be done. This paper presents a 35-year-old man complaining for 1 months a numbness and lowerlimbs heaviness. The neurological examination revealed paraplegia with a muscle power was 2/5. However, in lower limbs, the deep tendon reflexes were absent, walking was impossible also without any sensitive disorder. MRI revealed T7-T10 extradural spinal lesion. The tumor appeared as an hyperintense on T1 and T2-weighted images, and as heterogeneous on STIR. Total resection after dissecting the tissue around the tumor. The histopathological examination of the specimens obtained, showed that the lesion was made up of fatty tissue and angioma-like tissue. SAL is a rare benign tumor and considered as a specific clinico-pathological entity. MRI is considered to be the “gold standard” in diagnosing SAL and surgery appears to be the treatment of choice.

Abstract
Angiolipomas are rare primary benign tumors that can arise in the epidural canal and cause stenosis. Of the few cases of spinal angiolipomas described, most lesions have been located in the thoracic spine, and presentation of angiolipoma in the lumbar spine is very rare. The surgical management of a 39-year-old morbidly obese woman with angiolipoma that caused stenosis with neurogenic claudication and urinary changes is described. The lesion spanned L1-L2 and surgical management consisted of T12-L2 laminectomy and en-bloc resection of the lesion. During the latest follow-up, four years after the surgery, the patient’s neurological symptoms showed improvement and there was no recurrence.

Abstract
Angiolipomas are uncommon spinal tumors which differ from their cutaneous counterparts in having larger caliber vascular stroma. Although slow growing, they can cause rapid spinal cord compression and sudden-onset sensorimotor symptoms due to vascular engorgement, hemorrhage, or thrombosis. The goal of surgery is spinal decompression, and favorable outcome is the rule. We report a patient with spinal angiolipoma, vertebral hemangioma along with subcutaneous lipomas and angiolipomas, exhibiting the entire histopathological spectrum of these related soft-tissue tumors. Analysis of his family tree revealed a hereditary predilection. Familial angiolipomatosis is an uncommon genetic condition which has not been reported to occur with spinal angiolipomas thus far.

Abstract
Patients with spinal epidural abscesses (SEAs) may have a variable presentation. Such an infection has a typical appearance on magnetic resonance imaging (MRI) and enhances with gadolinium. We present a case that was a diagnostic challenge where pre- and intra-operative findings resulted in conflicting impressions. The mimicker was a spinal angiolipoma (SAL). The authors then provide a thorough review of this rare spinal neoplasm. A 55-year-old man presented with back pain, paresis, paresthesia, and urinary retention. MRI was indicative of a longitudinal epidural thoracic mass with a signal homogeneous to nearby fat, curvilinear vessels, and lack of enhancement. Although at emergent surgery, the lesion was found to contain abundant purulent material. Microbiology was positive for methicillin-resistant Staphylococcus aureus and consistent with SEA without evidence of neoplasia. While the imaging features were suggestive of an angiolipoma, the findings at surgery made SEA more likely, which were validated histopathologically. The diagnosis of SEA is often clear-cut, and the literature has reported only a few instances in which it masqueraded as another process such as lymphoma or myelitis. The case highlights SEA masquerading as an angiolipoma, and further demonstrates to clinicians that obtaining tissue diagnosis plays a crucial role diagnostically and therapeutically. SALs, on the other hand, are slow-growing tumors that can be infiltrating or noninfiltrating. They typically present with chronic symptoms and T1-MRI shows an inhomogeneous picture. Complete surgical excision is standard of care and patients tend to do well afterward.

Abstract
PURPOSE The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. METHODS A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed. The aim of this study is to describe the clinical, radiological, histological characteristics and the treatment of this tumor. RESULTS A total of nine patients were operated from January 01, 2000 to November 30, 2014. The average age of our patients was 51 years with ages that ranged from 29 to 65 with a male predominance. The period between onset of symptoms and diagnosis ranged from 24 months with an average 12 months. Posterior localization of the tumor was seen in all patients. Surgical resection was performed for all cases. The postoperative course has been satisfactory, with a complete recovery of neurological functions in all patients. CONCLUSIONS The spinal epidural angiolipomas is rare expansive process causing spinal cord compression. Treatment is exclusively surgical resection. The functional outcome of spinal epidural angiolipomas is particularly favorable with a complete neurological recovery is if the patient was quickly operated.

Abstract
BACKGROUND Spinal angiolipomas (SALs) are uncommon benign lesions that may present insidiously with back pain or acutely with weakness due to tumor bleeding/thrombosis. Given their rarity, these lesions are often overlooked in the differential diagnosis of epidural masses. The purpose of this article is to report the case of an epidural SAL and to conduct a literature review on the topic. METHODS A case report and review of the literature using the PubMed/Medline databases. All case reports and case series were reviewed up to June 2015. RESULTS A 65-year old female presented with neurogenic claudication and magnetic resonance imaging (MRI) revealed lumbar spinal stenosis. Following decompressive surgery, she experienced symptom resolution, but three months postoperatively she presented to the emergency department with acute paraparesis. A thoracic MRI revealed a lesion located between T8 and T10 causing severe spinal cord compression. Following emergent laminectomy and en bloc resection, the patient regained function and the lesion was diagnosed as SAL. Our literature review revealed 178 reported cases, with a female and thoracic predominance. The majority of patients underwent surgical treatment, achieving a gross total resection in most cases. Similarly, complete symptom resolution was the most common outcome. CONCLUSION Spinal angiolipomas are uncommon spinal tumors. However, they may be treated as any other space-occupying lesion, and surgical resection allows for complete symptom recovery in most patients.

Abstract
A true adult spinal lipoma is an exceedingly rare cause of lumbar compression neuropathy. Only 5 cases of true extradural intraforaminal lipomas have been documented in the medical literature. The diagnostic criteria and treatment guidelines for this specific lipoma have yet to be established. This report features 3 histologically confirmed cases of extradural intraforaminal spinal lipomas that recently presented to the authors’ practice. In addition, the literature was surveyed to include the 5 previously reported cases of true adult extradural intraforaminal spinal lipomas. The consistency in presentation, response to surgical intervention, and postoperative recovery in these 8 cases supports surgical intervention at the time of diagnosis. The authors’ findings support elevated clinical suspicion, efficient diagnosis based on MRI, and early surgical intervention for this rare pathological entity. All cases presented in this report were symptomatic and occurred in the absence of other significant pathologies such as general spinal epidural lipomatosis, intradural lesions, tethering, or severe degenerative stenosis or herniated discs. The clinical, neuroradiological, and histological findings characteristic of a true adult extradural intraforaminal lipoma are emphasized to differentiate this lesion from the more common etiologies for lumbar compression neuropathy. Heightened awareness and clinical suspicion for the focal, foraminal spinal lipoma as a cause of radiculopathy symptoms will enable more efficient diagnosis and treatment.

Abstract
Lipomatosis of nerve (LN), or fibrolipomatous hamartoma, is a rare condition of fibrofatty enlargement of the peripheral nerves. It is associated with bony and soft tissue overgrowth in approximately one-third to two-thirds of cases. It most commonly affects the median nerve at the carpal tunnel or digital nerves in the hands and feet. The authors describe a patient with previously diagnosed hemihypertrophy of the trunk who had a history of large thoracic lipomas resected during infancy, a thoracic hump due to adipose proliferation within the thoracic paraspinal musculature, and scoliotic deformity. She had fatty infiltration in the thoracic spinal nerves on MRI, identical to findings pathognomonic of LN at better-known sites. Enlargement of the transverse processes at those levels and thickened ribs were also found. This case appears to be directly analogous to other instances of LN with overgrowth, except that this case involved axial nerves rather than the typical appendicular nerves.

Abstract
Spinal angiolipoma is an uncommon form of benign tumor. There are 142 reported cases and only one of acute paraplegia. We describe a case of a 39 year old male with acute spinal paraplegia angiolipoma in T4-T5 with surgical resolution three weeks after the onset of the neurological syndrome. Postoperative neurologic recovery was complete. The angiolipoma consists of mature fat cells and abnormal blood vessels. There are 2 types: non-infiltrating and infiltrating. Its clinical course is slow and progressive, it can be accelerated by vascular phenomena, intratumoral abscess, and pregnancy. There is just one report of spontaneous intratumoral hemorrhage and acute paraplegia, coinciding with our case. There is no consensus as to treatment, and release and complete resection are suggested, as it is a disease with good prognosis. Angiolipoma spinal epidural is a rare form of benign tumor, and the treatment of this pathology continues to be release and resection of the tumor, with a favorable prognosis, despite the delay in surgery, as in the case reported. Intratumoral bleeding should be considered a cause of acute spinal compression syndrome, as ocurred in our patient.

[PMID: 24071036 DOI: 10.1016/j.spinee.2013.06.057] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2012] [Revised: 02/05/2013] [Accepted: 06/14/2013] [Indexed: 02/03/2023]
Abstract
BACKGROUND Angiolipomas are rare benign tumors, accounting for 0.14% to 1.2% of all tumors of the spinal axis with vascular and fatty histological features. Spinal angiolipoma (SAL) is most commonly found in the thoracic region and has high signal on contrast enhanced fat-saturated T1-weighted imaging. Although the international literature is extensive, there are few cases reported in United States. OBJECTIVE To present a case of SAL located in the thoracolumbar region without high signal on contrast enhanced fat-saturated T1-weighted imaging and to review previously reported cases. STUDY DESIGN/METHODS Case report and review the literature. RESULTS Magnetic resonance imaging obtained in a 68-year-old man with a long history of lumbago showed a heterogeneous mass (T10-L1) hyperintense on T1-weighted imaging but not enhancing on suppression fat sequences, suggesting epidural hematoma. Surgical excision of the lesion was performed, and SAL was diagnosed and confirmed by pathology. The patient became asymptomatic. CONCLUSIONS The predominance of either vascular or fatty components inside the tumor might alter the expected results on magnetic resonance imaging with suppression fat sequences.

Abstract
Objective To describe the MRI findings in ten patients of spinal epidural angiolipoma for differentiated diagnosis presurgery. Materials and Methods Ten surgically proved cases of spinal epidural angiolipomas were retrospectively reviewed, and the lesion was classified according to the MR findings. Results Ten tumors were located in the superior (n = 4), middle (n = 2), or inferior (n = 4) thoracic level. The mass, with the spindle shape, was located in the posterior epidural space and extended parallel to the long axis of the spine. All lesions contained a fat and vascular element. The vascular content, correlating with the presence of hypointense regions on T1-weighted imaging (T1WI) and hyperintense signals on T2-weighted imaging, had marked enhancement. However, there were no flow void signs on MR images. All tumors were divided into two types based on the MR features. In type 1 (n = 3), the mass was predominantly composed of lipomatous tissue (> 50%) and contained only a few small angiomatous regions, which had a trabeculated or mottled appear. In type 2 (n = 7), the mass, however, was predominantly composed of vascular components (> 50%), which presented as large foci in the center of the mass. Conclusion Most spinal epidural angiolipomas exhibit hyperintensity on T1WI while the hypointense region on the noncontrast T1WI indicates to be vascular, which manifests an obvious enhancement with gadolinium administration.

Abstract
Spinal epidural angiolipomas are rare, benign tumors composed of mature lipocytes admixed with abnormal blood vessels. Only 128 cases of spinal epidural angiolipomas have been reported in literature till now. Spinal angiolipomas are predominantly located in the mid-thoracic region. We report a case of dorsal epidural angiolipoma in a 56-year-old male who presented with paraparesis and was diagnosed to have D4-5 epidural angiolipoma. Total surgical excision of the epidural angiolipoma was done and his paraparesis gradually improved.

Abstract
Spinal angiolipomas are rare lesions usually found in the epidural space of the thoracic spine. The infiltrating type of spinal angiolipomas is extremely rare. This report presents the case and reviews the related literature. A 58-year-old man was presented with a 7-month history of progressive weakness and sensory change of lower extremities. Magnetic resonance images showed a well-enhanced mass infiltrating the vertebral foramen at the T4-5 level. Resection of the tumor was performed. Histological study revealed the tumor as an angiolipoma. The patient was relieved from symptoms after tumor resection.

Abstract
Angiolipomas are rare tumors of the CNS that most frequently develop in the orbit, the cavernous space, and the epidural space of the spine. The authors report the case of a patient who presented with an angiolipoma of the cavernous space. Using data from the published literature and an experimental anatomical approach, they demonstrate that the cavernous space contains adipose tissue. Consequently, they suggest that angiolipomas constitute a characteristic tumor illustrating the interperiosteo-dural concept.
The authors report the clinical, radiological, and histological data of a patient who presented with a tumor of the cavernous space. In addition, they prepared 2 encephalic extremities (4 cavernous spaces) using a special anatomical preparation consisting of an injection of colored neoprene latex followed by a 6-month immersion in a formaldehyde solution enriched with hydrogen peroxide to soften the bone structures (coronal sections) while leaving the fat in the cavernous space intact.
This case report corroborates previously published clinical data and shows that the tumor was a hamartoma comprising mature fat cells associated with vascular proliferation. The tumor developed in the cavernous space, which is an interperiosteo-dural space extending from the sphenoid periosteum (osteoperiosteal layer) to the superior and lateral walls of the cavernous space (encephalic layer). This space represents an anatomical continuum extending from the coccyx to the orbit: the interperiosteo-dural concept. It contains fat tissue that is abundant at the level of the orbit and the epidural spinal space and sparser at the level of the cavernous spaces, as was shown in our anatomical study.
The authors suggest that angiolipomas represent a characteristic tumor that illustrates the interperiosteo-dural concept because they essentially develop in the fat tissue contained in these spaces.

Abstract
Spinal angiolipoma is a rare benign tumour. It usually presents as a slowly progressive compressive lesion. Bleeding in this tumour is extremely rare and is spontaneous and acute. This is the first reported case of post-traumatic bleeding from a spinal angiolipoma, who developed subacute progressive paraparesis. The pathological definition of this rare entity is not well established. Histologically it is distinct from cutaneous angiolipoma.
