Lumbar Morel-Lavallee lesion after trauma: a report of 2 cases

Morel-Lavallee syndrome is a posttraumatic soft tissue injury in which the subcutaneous tissue is broken off from the underlying fascia, creating a cavity filled with hematoma and liquefied fat. It commonly occurs over the greater trochanter and, rarely, may also occur in the lumbal region.Morel-Lavallee syndrome can be often diagnosed late because of ommitted diagnosis in emergency services. The emergency physician and radiologist must keep this syndrome in mind because early diagnosis can enable conservative management, whereas delayed diagnosis may lead to surgical exploration. In this article,we present the clinical and radiologic features of 2 cases of lumbar Morel-Lavallee syndrome detected after trauma.

Comment on "anatomical variations in branching pattern of arcus aorta: 64-slice CTA appearance (Ergun et al. Surg Radiol Anat doi: 10.1007/s00276-012-1063-3)".

The knowledge of the branching pattern of the arcus aorta is important to reduce catheterization failure and complications during interventional radiological procedure. Diagnostic and therapeutic pre-procedural knowledge of any anomalous branching pattern of the arcus aorta is important to reduce examination time, complications, and catheterization failure during endovascular procedure in cases of complex anatomical variations. Right-sided arcus aorta is a rare and usually asymptomatic condition. In symptomatic cases, dyspnea and chronic cough were seen as previously described [4] Type 5 arcus aorta pattern according to classification of Natsis et al. [3] is rarely seen. Both RSAA and type 5 arcus aorta pattern are shown in the present case. We reported the first case evaluating the MR angiographic findings of RSAA with bicarotid trunk in the English literature to the best of our knowledge. The studies of Ergun et al. and Natsis et al. [1, 3], different from our case study, were conducted with multidetector computed tomography angiography (MDCT). The knowledge of arcus aorta type and the possible presence of accompanied vascular anomaly are crucial in choosing endovascular approach. Both MDCT angiography and MR angiography are seen as the best non-invasive imaging method to detect vascular anomalies. MIP and 3D volume rendering images provide us detailed and important information about the vascular anomalies. To the editor,

Fusion defect in anterior arch of the atlas mimicking a fracture in a trauma patient.

A 22-year-old female patient was brought to the emergency department after a fall. No abnormal findings were found on her physical examination. Her cranial computed tomography scan was evaluated to be normal. An apparent hypodense line was detected on the anterior side of the first cervical vertebra (C1) (Figure). The lesion was suspected to be a fracture because the patient was brought to the emergency department owing to a trauma. Fortunately, there were no abnormal findings on her physical examination, and she did not state any trauma to the cervical region. Some sclerotic changes and digitation of the bony structures formed the hypodense line; midline location of the lesion, and the lack of soft-tissue lesions around that line made us to exclude the diagnosis of a fracture. Anterior arch cleft of the atlas was diagnosed, and the patient was advised for outpatient clinic follow-up.

Colloid cyst mimicking intracranial hemorrhage after head trauma.

Trauma patients consist vast majority of the patients who admit to emergency department, and most of them have a head trauma. A 58-year-old patient was taken to emergency department with head trauma, and a hyperdense lesion neighboring to third ventricle was detected. A diagnosis of colloid cyst was made in the patient who was being followed up for hemorrhage. In patients with head trauma, colloid cyst may easly be confused with intracranial hemorrhage due to hyperdensity. The aim of this report is to emphasize the importance of clinical thinking in the differential diagnosis of hyperdense lesion on computed tomography imaging of a patient with head injury.
