“…9,10 Complete excision of the ligamentum flavum till its insertion of the cyst assures a minimal rate of recurrence. 5,16 Wildi et al, 19 reported recurrence of the cyst in the remaining ligamentum in two patients within 1 year. While nearly 95% of all operated cysts can be entirely removed, dural adhesions are the major cause of incomplete operative excision.…”

Background Data: Ligamentum flavum cysts have rarely been reported, it is believed to be a result of degenerative process. Complete excision of the cyst leads to excellent results. Ligamentum flavum cysts have rarely been reported worldwide and never published as an Egyptian case. Purpose: To report a case of ligamentum flavum cysts in the lumbar spine. Study Design: Case Report. Patients and Methods: We reported a case of ligamentum flavum cyst at the level of L4-5 in a 45 year old Egyptian woman, meticulous complete excision of the cyst without any durotomy or CSF leakage. Histopathological examination reported myxoid degeneration of the ligamentum flavum with no synovial cells. Results: the patient was satisfied and all her symptoms were completely resolved with 1 year follow up. Conclusion: ligamentum flavum cyst should be put in mind when reading the MRI. Complete surgical excision should be carried meticulously. (2016ESJ123)

“…Most symptomatic cysts usually present with radiculopathy. The history and physical examination findings of these patients may resemble symptoms related to sciatica and disc herniation (11). Typically, cysts can cause radicular pain (97%), sensory (55%) or motor (39%) deficit, Lasèque sign (33%), abnormal reflexes (18%), and rarely present as cauda equina syndrome (1).…”

The term ligamentum flavum cyst is defined as a cystic formation arising from ligamentum flavum that is not lined with synovial epithelium (1). Ligamentum flavum cyst is a rare cause of spinal cord and nerve compression (2). It was first defined by Moiel et al. (3) in 1967. It occurs most frequently in the lower lumbar region (4). It may cause neurological complaints due to spinal canal stenosis or lumbar root compression (5). These cysts accompany degenerative changes in the spine. It can be distinguished from synovial and other degenerative spinal cysts based on localization and histopathological features (6). We aimed to present two cases of ligamentum flavum cysts that we diagnosed based on original magnetic resonance imaging (MRI) findings and confirmed one histopathologically. Case Reports Case 1 A lumbar MRI was requested for a 54-year-old male patient with low back pain, slow-developing gait disturbance, hip, and right leg pain. Neurological examination revealed normal motor functions, but sensory impairment in the right L4 dermatome. The patient's medical history included hypertension and diabetes. No pathology was observed in laboratory tests. Degenerative changes were observed on the direct X-ray of the lumbosacral vertebra. Multilevel facet arthropathy, more prominent in L3-L4, was observed in lumbar MRI. A 17x5.5 mm ligamentum flavum cyst, which was hypointense on T1-weighted images (T1WI) and hyperintense on T2-WI, was found at L3-L4 level. The cyst caused right lateral recess stenosis by compressing thecal sac and spinal

“…There are no pertinent clinical symptoms; however, the spinal canal can impinge upon and displace neural structures and can lead to neurologic symptoms. The majority of symptomatic cysts usually present with radiculopathy, such as sciatica in case of lumbar cysts, and can resemble symptoms related to disc herniation [13] , [14] . Neuroimaging, especially MRI, plays a vital role in the preoperative diagnosis of this condition.…”

Ligamentum flavum cyst: An uncommon but recognizable and surgically correctable category of juxtafacet cyst

Ligamentum flavum cyst is considered as a category of juxtafacet cyst and is recognized to be rare cause of cord compression and radiculopathy. The pathogenesis of these cysts is not yet fully understood, but it has been proposed that continuous stress to this ligament due to minor repetitive trauma, such as in spondylolisthesis and degenerative disc disease, may lead to the development of cyst. Intraspinal cyst can encroach and displace neural structures that can lead to neurologic symptoms. Although a rare entity, intraspinal cyst should be included in the causative factors of neurogenic claudication or lumbar radiculopathy based on typical magnetic resonance imaging appearance. Timely diagnosis is also imperative in this condition due to a better surgical outcome.
