Lumbar Morel-Lavallée lesion: a case report and review of the literature.

OBJECTIVES: Here we describe a rare post-traumatic lesion and discuss its management. BACKGROUND: Lumbar Morel-Lavallée is a rarely reported lesion. The cause is usually post-traumatic in a polytraumatic context, and care is often focused elsewhere. This leads to misdiagnosis with a risk of chronic pain and infection. In addition, there is no consensus for the management as few cases have been reported so far. CASE REPORT: A 35-year-old African woman was involved in a motor accident. Physical examination at the emergency department revealed moderate head trauma, a lumbar inflammatory mass, and a closed leg fracture. She underwent a whole-body computed tomography scan, which revealed a left frontal brain contusion and a large left paraspinal mass in favor of a lumbar Morel-Lavallée lesion. She benefited from osteosynthesis and conservative management of the cerebral and lumbar lesions. After 4 days, she complained of headaches and vomiting. Magnetic resonance imaging was requested. There was resorption of the cerebral contusion, and the lumbar mass was heterogeneous. She was discharged 10 days later without lower back pain and fully recovered from the headaches. Ultrasound of the lumbar soft tissue performed a month later showed no more collection. CONCLUSION: More frequent in young men, lumbar Morel-Lavallée lesion is underdiagnosed. Thus, there is no consensus on its treatment. However, conservative management followed by close monitoring is advisable in the acute phase. Other therapy includes surgery with or without the use of sclerosing agents. Early diagnosis prevents infections. Although the diagnosis is clinical, magnetic resonance imaging is the critical paraclinical examination for its assessment. Our case is interesting because it occurs in a woman following polytrauma, and to the best of our knowledge, it is an extremely rare lesion, especially in women.

Surgical management of a thoracic chordoma: A case report and literature review.

BACKGROUND: Chordomas are rare benign, but locally aggressive tumors that are regularly encountered in the clivus and sacrum. Although they are rarely found in the thoracic spine, they can contribute not only to local bone destruction and spinal instability, lead to cord compression, and major neurological deficits. CASE DESCRIPTION: A 56 year-old-male originally underwent a T12 laminectomy with debulking for a thoracic chordoma. Two years later, the lesion recurred contributing to a significant paraparesis. The new MR showed a T2 hyper intense lesion with huge epidural extension that warranted a 360° surgical decompression and fusion. The histopathology from both surgeries confirmed the diagnosis of a chordoma. CONCLUSION: Combined 360° decompression and fusion was warranted to resect a T12 chordoma that recurred 2 years following an original laminectomy with debulking procedure.

Cervical Pott's disease: case report and review of the literature.

Tuberculosis is a major public health problem in the world. Spinal tuberculosis (Pott disease) is a frequently encountered extrapulmonary form of the disease. Cervical spinal tuberculosis is relatively rare. We report the case of a 66-year-old patient admitted for cervical Pott's disease managed surgically and the positive outcome. A patient with a history of pulmonary tuberculosis present 3 months ago persistent neck pain with tingling and heaviness in both upper limbs. The neurological examination was normal without any sensory or motor deficit. Spinal cord magnetic resonance imaging (MRI) showed a lesion centered on the vertebral body of C4 with spinal cord compression and epiduritis without signs of spinal cord injury. The patient underwent a corpectomy of C3 and C4 with an iliac graft and anterior cervical plate. The anatomopathological examination revealed a Pott disease. He was therefore put on antituberculous chemotherapy for 12 months. Three months later the neck pain and tingling disappeared in the upper limbs. Cervical Pott's disease is relatively rare. Surgical management is indicated in the case of spinal instability or spinal cord compression.
