Meniscal ramp lesions are a special type of injury that affects the periphery of the posterior horn of the medial meniscus (PHMM) and/or its meniscocapsular attachments. They are strongly associated with acute and chronic anterior cruciate ligament (ACL) tears. These lesions have gained much prominence in recent years, due to a significant increase in their diagnosis and their important biomechanical involvement in the knee. It is known that their presence in ACL-deficient knees is related to instability and if they are not repaired during ACL reconstruction, they can ultimately cause the failure of the graft. Since this type of injury is often underdiagnosed due to its localization at the "blind" point of arthroscopic vision, it is crucial to make an accurate preoperative diagnosis of them with MRI. The objective of this article is to review the recent literature regarding meniscal ramp lesions and to summarize the anatomical, biomechanical and fundamentally diagnostic aspects, emphasizing the radiological findings described until now.

PURPOSE: Giant cell tumor of soft tissue (GCT-ST) is an extremely rare lesion with an unpredictable behavior. The histological appearance closely resembles that of giant cell tumor of bone and, as such, has been characterized as the soft-tissue equivalent. MATERIALS AND METHODS: We describe the clinical, histological and radiological features of an unusual magnetic resonance imaging (MRI) and deep intramuscular location of GCT-ST with fluid-fluid levels (FFLs) simulating other soft tissue tumors or a hydatid cyst in a 52-year-old man. The lesion was resected. RESULTS: Neither metastasis nor recurrence has occurred in the 6-month period since resection. A review of the literature did not reveal any similar description of intramuscular GCT-ST. CONCLUSION: GCT-ST should be included in the differential diagnosis of soft tissue tumors with FFLs.
