ABSTRACT
Lumbo-pelvic pain is a common and non-specific problem during pregnancy and postpartum. Although perinatal pyogenic sacroiliitis is uncommon during this time, it might be difficult to distinguish from reactive sacroiliitis in women who are experiencing significant lower back and pelvic girdle pain, as the symptoms and signs are not clear and the tests are not definitive. A 34-year-old primigravida went to the emergency department with severe lower back pain radiating to the right gluteal region and down to the back of the right thigh. This pain began 12 days prior to her presentation and eventually worsened to the point that she could not stand or walk. Her vital signs were within normal ranges, and she was experiencing a fever. Apart from a slight widening of the symphysis pubis, her pelvic and lumbo-sacral pain X-rays revealed no important findings. With the clinical impression of right lumbo-pelvic pain, the patient was admitted for pain management and further inquiries. Despite the fact that the antibiotherapy was prescribed to treat a urinary tract infection, the significant recovery of the patient's symptoms, even in the absence of a definitive culture of aspirate from the right sacroiliac joint, supported the diagnosis of pyogenic sacroiliitis.
ABSTRACT
Lymphoma is the seventh most common type of malignancy in both males and females. It may develop in any location where lymphomatous tissue exists. Although extranodal presentation in the lower limb and pelvis are uncommon, it could present with diverse manifestations. We report an unusual case of primary extranodal large B-cell lymphoma of the ankle joint initially presumed to be a chronic osteomyelitis. This case report discusses the impact of imaging studies on decision-making and highlights the need to consider malignancy in chronic infections.
ABSTRACT
Magnetic resonance (MR) imaging is a useful tool for assessing the anterior cruciate ligament (ACL) graft when its integrity is in question, with some limitations. It can differentiate between a graft that is partially or completely torn. Several primary (direct) and secondary (indirect) signs have been described. Graft continuity in the coronal plane and normal graft thickness in the coronal or sagittal plane are the most valuable primary signs in excluding full thickness tear. Of the secondary signs, the anterior tibial translation and the uncovered lateral meniscus sign are the most useful in differentiating a torn from an intact graft. Some of the primary and secondary signs of a native ACL tear are yet to be assessed for accuracy in detecting grafts tear, but they are a helpful guide especially when combined. These include the deep lateral femoral sulcus, the posterior cruciate ligament (PCL) angle, and the PCL curvature values.
