“…[17][18][19][20][21][22][23][24][25] The medical history of the patients is often omitted, but it may include trauma (fall from a height), 26 degenerative disorders (spondylolisthesis, degenerative disc disease, scoliosis), 21,22,27 congenital disorders (spondylolysis and Scheuermann's kyphosis), 21,27,28 or neoplasia (plasmacytoma). 29,30 With a few exceptions, a traumatic mechanism occurs before the formation of an acute SN. Of the 44 published cases of an acute SN, 41 patients (93%) reported some kind of injury prior to the onset of symptoms.…”

Study Design This case report describes an acute Schmorl's node (SN) in an elite monofin athlete during exercise. The patient presented with severe back pain and leg numbness and was managed successfully with conservative treatment. Objective The aim of our communication was to describe a rare presentation of a common pathological condition during an intense sport. Background Swimming is not generally considered to be a sport activity that leads to spinal injuries. SNs are usually asymptomatic lesions, incidentally found on imaging studies. There is no correlation between swimming and symptomatic SN formation. Case Report A 16-year-old monofin elite athlete suffered from an acute nonradiating back pain during extreme exercise. His back pain was associated with a fracture of the superior L5 end plate and an acute SN at the L5 vertebral body with perilesional bone marrow edema. The pain resolved with nonsteroidal anti-inflammatory drugs and bed rest. The athlete had an excellent outcome and returned to his training activities 6 months after his incident. Conclusion SN should be considered in the differential diagnosis of severe back pain, especially in sport-related injuries. SNs present with characteristic imaging findings. Due to the benign nature of these lesions, surveillance-only management may be the best course of action.

“…21,22 En este punto, sugerimos realizar una biopsia durante el procedimiento, antes de inyectar el cemento, dados los datos clínicos de pérdida de peso y la similitud que existe en el patrón de señal de la RM entre un NS agudo y con un fondo neoplásico. 23 Es muy raro que la primera manifestación de un carcinoma pancreático sea una metástasis vertebral. Las localizaciones más frecuentes de metástasis en el cáncer de páncreas son el hígado y el peritoneo.…”

Las hernias discales intraesponjosas vertebrales o nódulos de Schmörl consisten en una herniación o una extrusión del núcleo pulposo del disco intervertebral a través del platillo vertebral hacia el cuerpo adyacente. Suelen asociarse a deformidades vertebrales, como la enfermedad de Scheuermann, o a enfermedades reumáticas, como la espondilitis anquilopoyética. En general, son hallazgos casuales y cuadros asintomáticos; son pocos los casos publicados de nódulos sintomáticos. Su aparición estaría relacionada con un platillo vertebral debilitado por traumatismo o estrés repetido. Cuando el nódulo es agudo o reciente, puede ser difícil diferenciar la degeneración benigna de una infiltración maligna o una infección. Presentamos un caso inusual de un nódulo de Schmörl doloroso en un hombre sin antecedentes de relevancia, que enmascaró una lesión metastásica de carcinoma pancreático a nivel lumbar. Se realiza una revisión bibliográfica. ABSTRACTIntraosseous disc herniation –or Schmörl nodes (SN)– are a herniation or prolapse of the nucleus pulposus of the intervertebral disc through the vertebral plate and into the adjacent vertebral body. They are usually associated with vertebral deformities, suchas Scheuermann’s disease, or rheumatic diseases, such as ankylopoietic spondylitis. In general, they are spontaneous and asymptomatic findings, and there are only a few reported cases of symptomatic nodes. The etiology is supposedly related to a weakened spinal plate due to trauma or repeated stress. When the node is acute or recent, it can be difficult to differentiate a benign degeneration from a malignant infiltration or infection. In this paper, we discuss the unusual case of a painful Schmörl node in a man with no relevant history and a masked metastatic lumbar spinal tumor originated from pancreatic cancer. We performed a literature review.

“…In addition to SNa associated with low BMD ( 22 ) and SNa associated with acute high energy trauma ( 24 , 25 , 38 , 43 ), various other etiology with weakening of the endplate, including infectious spondylodiscitis or other inflammatory spine diseases such as ankylosing spondylitis, may also cause SNa ( 23 , 44 ) ( Figure 23 ). Tumorous changes of a vertebra can also increase the fragility of an endplate, and lead to disc materials herniation through endplate into the vertebral spongy bone and form SNa ( 45 , 46 ). Peng et al ( 47 ) reported that SNa can be the end result of ischaemic necrosis beneath the cartilaginous endplate.…”

Schmorl’s Node Developing in the Lumbar Vertebra Affected With Metastatic Carcinoma: Correlation Magnetic Resonance Imaging With Histological Findings

Abstract: MR features consisting of two different signal patterns are characteristic for Schmorl's node with a neoplastic background. The conditions should be distinguished from Schmorl's nodes in an acute phase, which show similar MR features.
