Ligamentum flavum hematoma in the rigid thoracic spinal segments

Ligamentum flavum hematomas: Why does it mostly occur in old Asian males? Interesting point of reported cases: Review and case report

Hematoma of the ligamentum flavum (LF) is a rare cause of neural compression and sciatica. Currently, the etiology and epidemiological characteristics of ligamentum flavum hematoma (LFH) are unknown and epidemiological investigations using rewieving of reported cases have not been performed. We report the case of a 63-year-old man with a LFH compressing the spinal canal at the left L2-L3 level, rewieved relevant literature. In Medline research, wefound a total of 50 reported cases with LFHs, and the interesting point of these cases were analyzed. Many of cases were old males. Interestingly, 39 of the 50 cases were reported from Asian countries. The ages of 42 patients could be verified. The youngest age was 45 years, oldest age was 81 years, and mean age was 66.07 years. Thirty-three out of these 42 patients (78.53%) were older than 60 years. An important aspect of the present review is to bring attention for occurrence in older Asian males. With an increasing number of elderly people in the general population, there is a need to investigate risk factors such as sexual gender, age, and geographic location for LFH.

A contrast-enhancing lumbar ligamentum flavum haematoma

We present a case of lower back pain with lumbar nerve compromise due to a ligamentum flavum haematoma which was successfully treated surgically. A 62-year-old man was evaluated for lower back pain with associated leg pain and early signs of cauda equina syndrome. MRI of the lumbar spine demonstrated a contrast-enhancing mass adjacent to the lamina of L3 which was causing severe canal stenosis. Surgical excision of the lesion was recommended. The patient underwent an L3 laminectomy with excision of the epidural lesion. Histopathology showed it to be a haematoma of the ligamentum flavum with no untoward features. The patient recovered without complication.

Ligamentum flavum hematomas of the cervical and thoracic spine

OBJECTIVE

To report extremely rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Only six cases of thoracic ligamentum flavum hematomas and three cases of cervical ligamentum flavum hematomas have been reported so far.

METHODS

Two patients presented with tetraparesis and one patient presented with radicular pain and paresthesias in the T3 dermatome. MRI was performed in two patients, which showed a posterior intraspinal mass, continuous with the ligamentum flavum. The mass was moderately hypointense on T2-weighted images and hyperintense on T1-weighted images with no contrast enhancement. The third patient underwent cervical myelography because of a cardiac pacemaker. The myelography showed an intraspinal posterior mass with compression of the dural sac at C3/C4.

RESULTS

All patients underwent a hemilaminectomy to resect the ligamentum flavum hematoma and recovered completely afterwords, and did not experience a recurrence during follow-up of at least 2 years.

CONCLUSION

This case series shows rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Surgery achieved complete recovery of the preoperative symptoms in all patients within days.

Ligamentum flavum hematoma: a case report and literature review

The aim is to present a rare case of ligamentum flavum hematoma in the lumbar region, discuss its physiopathology and treatment and review the literature. A woman aged 68 presented with neurogenic claudication due to degenerative lumbar spondylolisthesis that evolved into a sudden worsening with cauda equina syndrome. The magnetic resonance imagining (MRI) showed signs of degeneration of the lumbar spine, with a narrow spinal canal from L2 to S1, anterolisthesis L4 L5 and an expansive lesion hyperintense on T1-weighted and hypointense on T2-weighted images considered compatible with hematoma in the topography of the yellow ligament in L1-L2. The patient underwent laminectomy and lumbar fixation. Her evolution was good in the postoperative period and at 18 months of follow-up hse walked alone, despite the pain that is controlled with simple medications. Even though rare, it seems that ligamentum flavum hematoma has a relationship with the degeneration and rupture of small vessels associated with micro trauma to the spine. Its physiopathology is not well defined and treatment is similar to other spine compression processes.

Spontaneous ligamentum flavum hematoma in the rigid thoracic spine : a case report and review of the literature

Ligamentum flavum hematoma is a rare condition. Twenty cases including present case have been reported in English-language literature. Among them, only one case reported in pure thoracic spine. A 72-year-old man presented with thoracic myelopathy without precedent cause. Magnetic resonance images revealed a posterior semicircular mass which was located in T7 and T8 level compressing the spinal cord dorsally. T7-8 total laminectomy and extirpation of the mass was performed. One month later following surgery, the patient fully recovered to normal state. Pathologic result was confirmed as ligamentum flavum hematoma. Ligamentum flavum hematoma of rigid thoracic spine is a very rare disease entity. Most reported cases were confined to mobile cervical and lumbar spine. Surgeons should be aware that there seems to be another different pathogenesis other than previously reported cases of mobile cervical and lumbar spine.

Chronic subdural hematoma coexisting with ligamentum flavum hematoma in the lumbar spine: a case report

We present a case of a chronic spinal subdural hematoma combined with a ligamentum flavum hematoma in the lumbar spine treated surgically. An 83-year-old woman receiving antiplatelet medicine due to an angina suffered from pain in her lower extremity and gait disturbance after a backward fall. Radiological findings including magnetic resonance imaging (MRI) revealed hematoma in the ligamentum flavum at the level of L2 - L3 and a chronic subdural hematoma at the level from L3 to L5. Laminectomy through L2 to L5 was performed and a hematoma existing in the ligamentum flavum and cystic mass was removed. A chronic subdural hematoma was spontaneously evacuated after splitting of the dura mater and an intact arachnoid membrane was observed with no leakage of cerebrospinal fluid. Her clinical symptoms completely disappeared after surgery. To the best of our knowledge, this is the first case of combination of chronic subdural hematoma and ligamentum flavum hematoma in the lumbar spine treated by surgery. Chronic spinal subdural hematoma and hematoma in the ligamentum flavum should be considered as a cause of progressive nerve root compression in patients with anticoagulant therapy, and an appropriate pre-operative diagnosis would be needed to achieve complete decompression of subdural and epidural hematoma.

Case reports: a rare cause of radicular complaints: ligamentum flavum hematoma

Hematomas in the lumbar ligamentum flavum are rare and may generate signs and symptoms of lumbar nerve root compression or neurogenic claudication similar to the far more common degenerative diseases. The pathogenesis of these hematomas is unclear. Ruptured irregular vessels of the degenerated and hypertrophic ligamentum flavum were assumed. We diagnosed three patients with a flavum hematoma intraoperatively leading to radicular complaints and spinal claudication. One occurred as a complication of local infiltration therapy, and the other two patients reported minor trauma as the releasing factor. Using spinal magnetic resonance imaging, a preoperative diagnosis is possible but the differentiation to synovial cysts is difficult. Surgical resection of the ligamentum flavum, including the hematoma, provided adequate treatment in these patients.

Ligamentum Flavum Hematoma in the Cervical Spine-Case Report-

A 67-year-old man presented with a rare case of ligamentum flavum hematoma manifesting as progressive tetraplegia following cervical traction therapy. Magnetic resonance imaging of the cervical spine showed a posterior mass that was continuous with the ligamentum flavum at the C3-4 levels. Complete resection of the mass that contained brownish hemorrhage was performed, resulting in excellent symptom relief. We speculate that repeated trivial trauma to the degenerative ligamentum flavum was the main predisposing factor in the present case. Ligamentum flavum hematoma is a rare cause of spinal root or cord compression which typically occurs in the lower thoracic or lumbar spine, but may also appear in the cervical spine.
