It refers to a striated or vertically oriented linear pattern seen on imaging, resembling the appearance of corduroy fabric. [1] This sign is most commonly identified on lateral radiographs or magnetic resonance imaging (MRI) of the spine and is an important diagnostic marker for benign conditions such as vertebral hemangiomas.
Vertebral hemangiomas are observed throughout any age, although most are diagnosed in people within their 50s alongside a higher presence in females with a 1:1.5 male-to-female ratio. They often present in the vertebral body of the thoracic and lumbar spine with potential to extend into the posterior arch. They can involve a single or multiple ...
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma , known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.
Common types of medical imaging include X-rays, computer tomography scan (CT), Magnetic resonance imaging (MRI), myelography, and bone scans. [1] [5] MRI is the imaging of choice for spinal tumors. [1] The MRI protocol that is most frequently used includes T1-weighted and T2-weighted sequences, including contrast enhanced T1-weighted sequences. [1]
Small hemangioma on the scalp of a two-year-old female. Gradient-echo T2WI magnetic resonance imaging is the most sensitive method for diagnosing cavernous hemangiomas. [21] MRI is such a powerful tool for diagnosis that it has led to an increase in diagnosis of cavernous hemangiomas since the technology's advent in the 1980s. [16]
Magnetic resonance myelography (MR myelography or MRI myelography) is a noninvasive medical imaging technique that can provide anatomic information about the subarachnoid space. It is a type of MRI examination that uses a contrast medium and magnetic resonance imaging scanner to detect pathology of the spinal cord , including the location of a ...
Neurologic signs result from severe angulation of the spine, narrowing of the spinal canal, instability of the spine, and luxation or fracture of the vertebrae. Signs include rear limb weakness or paralysis, urinary or fecal incontinence, and spinal pain. [5] Most cases of hemivertebrae have no or mild symptoms, so treatment is usually ...
Angiolymphoid hyperplasia with eosinophilia (also known as: [1] "Epithelioid hemangioma," "Histiocytoid hemangioma," "Inflammatory angiomatous nodule," "Intravenous atypical vascular proliferation," "Papular angioplasia," "Inflammatory arteriovenous hemangioma," and "Pseudopyogenic granuloma") usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck ...
