AJR 2003; 181:761-769 Hypointense Synovial Lesions on T2-Weighted Images: Differential Diagnosis with Pathologic Correlation José A. Narváez, Javier Narváez, Raúl Ortega1, Eugenia De Lama1, Yolanda Roca1 and Noemí Vidal
Synovial tissue that lines joint cavities, bursae, and tendinous sheaths is generally too thin to be shown on MRI. However, as synovial tissue thickens...

4 weeks after surgery, the patient started to complain of increasing pain and gradual swelling of his operated knee. He presented to the emergency room due to agonizing knee pain 2 weeks later. His left knee was very swollen, especially on the anterolateral side. It was warm and tender and...

We report a case of intra-articular fracture of the knee joint showing three layers within lipohemarthrosis. Sagittal ultrasonography showed three layers (double fluid-fluid level): a superior hyperechoic layer of fat, an intermediate anechoic layer of serum, and an inferior hypoechoic layer of red blood cells. Horizontal computed tomography imaging demonstrated...

We made a prospective arthroscopic study of 106 skeletally mature male sportsmen with an average age of 28.35 years (16.8 to 44) who presented with an acute haemarthrosis of the knee due to sporting activities. We excluded those with patellar dislocations, radiographic bone injuries, extra-articular ligamentous lesions or a previous...

Knee effusions may be the result of trauma, overuse or systemic disease. An understanding of knee pathoanatomy is an invaluable part of making the correct diagnosis and formulating a treatment plan. Taking a thorough medical history is the key component of the evaluation. The most common traumatic causes of knee...

Distortions and contusions of the knee are common. Fairly often they will result in hemarthrosis. The purpose of this study was to evaluate the findings in patients with acute traumatic hemarthrosis of the knee and based on these findings estimate the necessity of acute arthroscopic examination.
CONCLUSIONS: Based on our findings...

A 26 year old woman presented to the accident and emergency department with a painful right elbow. There had been no history of trauma. Clinical examination suggested an effusion, which was confirmed on radiological examination. Her elbow was aspirated and revealed a haemarthrosis. Subsequent investigations revealed a diagnosis of von...

A short cut review was carried out to establish whether aspiration of a traumatic knee haemarthrosis improved the patient's symptoms. Altogether 267 papers were found using the reported search, of which none answered the question posed. Further research is needed in this area.

- non-bloody effusion suggests an irrative synovitis that may be caused by degenerative meniscus or a chronic process with no super imposed acute injury;
- absence of hemarthrosis is not indication of less severe ligament injury,...

A 19-year-old man with a complete cervical spinal cord injury was found to have bilateral hip effusions. Joint aspiration yielded a right sterile hydroarthrosis and a left sterile hemarthrosis.
CONCLUSION: This case indicates that hip effusion may be a similar, less-common occurrence than knee effusion in patients with spinal cord...

PURPOSE: To determine if fluid-fluid levels on horizontal-beam radiographs of posttraumatic knee joints always represent lipohemarthrosis.
CONCLUSION: Single fluid-fluid levels in posttraumatic knee joints do not necessarily represent a lipohemarthrosis. Double fluid-fluid levels are a more specific finding.
Fluid-fluid levels in injured knees: do they always represent lipohemarthrosis? Lugo-Olivieri CH, Scott WW...

Type 1 neurofibromatosis is one of the most common autosomal-dominant disorders and often includes orthopedic manifestations. We report the case of a 48-year-old woman with hemarthrosis caused by a popliteal cyst infiltrated by a diffuse neurofibroma associated with angiodysplasia. Surgical resection of this tumor was followed by postoperative hemorrhagic complications
Hemarthrosis:...

Letter commenting on an article indicating haemarthrosis may be the presenting complaint of scurvy. All cases had poor diets typical of elderly people hampered by joint disease. It is suggested that this association is underdiagnosied.

Arthroscopy was used as a gold standard in both selected studies. MRI lacks both the sensitivity required for a SnOut and specificity required for a SpIn on this evidence. The evidence only applies to the conditions stated (haemarthrosis and investigation within one week) and different results might be found at different times.
Clinical bottom line The evidence does...

Several spontaneous episodes of haemarthroses of the knee in a young man led to repeated arthroscopic examinations and one arthrotomy of the affected joint until a juxta-articular haemangiohamartoma was indicated by angiogram. Excision of the malformation stopped the bleeding tendency.
Recurrent spontaneous haemarthrosis of the knee associated with a synovial and...
