Marrow Edema

The aim of this study is to assess whether perifocal bone marrow edema (BME) in patients with osteoid osteoma (OO) can be accurately detected on dual-layer spectral CT (DLCT) with three-material decomposition. To that end, 18 patients with OO (25.33 ± 12.44 years; 7 females) were pairwise-matched with 18 patients (26.72 ± 9.65 years; 9 females) admitted for suspected pathologies other than OO in the same anatomic location but negative imaging findings. All patients were examined with DLCT and MRI. DLCT data was decomposed into hydroxyapatite and water- and fat-equivalent volume fraction maps. Two radiologists assessed DLCT-based volume fraction maps for the presence of perifocal BME, using a Likert scale (1 = no edema; 2 = likely no edema; 3 = likely edema; 4 = edema). Accuracy, sensitivity, and specificity for the detection of BME on DLCT were analyzed using MR findings as standard of reference. For the detection of BME in patients with OO, DLCT showed a sensitivity of 0.92, a specificity of 0.94, and an accuracy of 0.92 for both radiologists. Interreader agreement for the assessment of BME with DLCT was substantial (weighted κ = 0.78; 95% CI, 0.59, 0.94). DLCT with material-specific volume fraction maps allowed accurate detection of BME in patients with OO. This may spare patients additional examinations and facilitate the diagnosis of OO.

AbstractSubchondral, osteochondral, and chondral lesions of unknown cause are often encountered, especially in the knee joint. These are mainly idiopathic bone marrow edema syndrome, osteochondrosis dissecans, and cartilage delaminations. The literature on these diseases is sparse and often confusing and inconsistent. Because there is little evidence, this article was written as a perspective on these conditions. It offers an overview of the literature with personal comments and opinions based on observations from many years of clinical practice. The main goal is to highlight clinically important features and provide a practical guide for dealing with various magnetic resonance imaging findings in everyday work. The article also discusses several terms commonly used in relation to these diseases and their differential diagnoses.

Background Since the diagnosis of post-arthroscopic chondrolysis is very difficult, it can be underdiagnosed and confused with other diseases in clinical practice. Purpose To propose imaging features of post-arthroscopic radiocarpal chondrolysis (PRCC) and to compare these with osteoarthritis associated with scapholunate dissociation which are the most common misdiagnoses of PRCC. Material and Methods To identify missed diagnoses of PRCC, 994 magnetic resonance imaging scans performed in 910 patients were retrospectively reviewed. After the identification of 73 patients who exhibited significant radiocarpal cartilage loss, 11 were diagnosed with PRCC. Since scapholunate advanced collapse was the most common incorrect diagnosis of PRCC (4/11), the imaging findings were compared among the 11 patients with PRCC and 14 patients with osteoarthritis caused by scapholunate dissociation who were diagnosed in the same period. The following imaging features were evaluated: scapholunate dissociation; the center of disease and grade of radiocarpal joint destruction; characteristics of bone marrow edema; the presence of radial styloid and distal scaphoid osteophytes; and the extent of joint effusion and synovitis. Results The imaging diagnosis of PRCC was significantly differentiated from osteoarthritis associated with scapholunate dissociation based on occurrence at a younger age, bone marrow edema crossing the joint, center of disease in the proximal radioscaphoid joint, and absence of radial styloid and scaphoid osteophytes ( P < 0.05). PRCC occasionally presented with arch-shape bone marrow edema based on the proximal carpal row. Conclusion The diagnosis of PRCC can be aided if its characteristic imaging findings are differentiated from other disease entities in patients with a history of arthroscopy.

This case report describes a well-documented birth and evolution of an osteoid osteoma at the talus. Although initial radiologic images indicate mild bone marrow edema at first (without nidus), subsequent magnetic resonance imaging and computed tomographic images reveal pathognomonic nidus at the talus. During the evolution of the lesion, typical night pain was coincident with the occurrence of the nidus, as seen on magnetic resonance imaging. This may be interpreted that nidus formation may be related to the night pain. In this report, the first finding was bone marrow edema. Although our classic knowledge was that the edema follows the lesion, this report makes a difference. The relationship between bone marrow edema and osteoid osteoma has not been questioned in the literature before. We speculate that this report brings to mind, the question of which comes first? A bone marrow edema or nidus? Another question is: Does osteoid osteoma always start with such a dust cloud in the bone as we presented herein?
