Sacral stress fracture in a young-adult, long-distance runner: an underestimated cause of low back pain.

Sacral stress fractures (SSFs) in physically active young patients are frequently misdiagnosed due to the lack of specificity of signs and symptoms. Over the last years, these injuries have been described as rare, although some studies report that the incidence of an SSF in athletes may be as high as 20%.We describe a case of a male long-distance runner in his late 20s with a 1-month undiagnosed SSF. The patient complaints included insidious right low back and buttock pain without trauma that started after running a marathon. MRI revealed an extensive area of bone marrow oedema in the right sacral ala consistent with an SSF.This case highlights the importance of investigating SSF in young-athlete patients who were otherwise healthy, using appropriate imaging modalities to assess the presence and morphology of a fracture.

Quadratus Femoris Tendinopathy as an Underreported Cause of Groin Pain: Case Report.

Groin pain is a cause of mobility impairment, and its diverse presentation can make the diagnosis difficult. Quadratus femoris muscle tendinopathy is a poorly described etiology, but its diagnosis is important for the success of the therapeutic program. The authors present the case of an 18-year-old woman who complained of chronic pain in the left inguinal region due to regular ballet practice. Physical examination revealed restriction in the left hip medial rotation. Ultrasound and radiographic studies were normal. Magnetic resonance imaging showed asymmetry in the signal intensity of the quadratus femoris muscle. The patient improved significantly after a rehabilitation program that included quadratus femoris muscle-specific exercises. Diagnostic accuracy and an understanding of segmental biomechanics ensure greater effectiveness in the therapeutic approach.

Mondor's Disease: A Rare Cause of Chest Pain.

INTRODUCTION: Chest pain is a very frequent reason for seeking medical care. When there is no obvious cause, patients are sometimes subjected to tests and treatments that may be unnecessary and potentially harmful. Mondor's disease is a rare but usually benign and self-limited entity characterized by thrombophlebitis in a specific region. CASE REPORT: We report the clinical case of a 51-year-old man admitted to the emergency department with a 24-hour history of left chest pain with no other symptoms. Physical examination revealed a palpable subcutaneous cord-like structure that ultrasound confirmed to be thrombophlebitis of a superficial vein in the mammary region. Secondary causes were ruled out, and the condition resolved with ibuprofen and the application of local ice. DISCUSSION: Mondor's disease can be associated with neoplasms, trauma or hyperviscosity states, but it is mostly idiopathic. Usually, it resolves completely in 4-8 weeks without specific treatment. Because this infrequent diagnosis mainly relies on clinical findings, it is important that clinicians can recognize the syndrome. LEARNING POINTS: Mondor's disease is a rare but benign disease, with no proof that specific treatment, such as anticoagulation, is beneficial.It may be secondary to underlying disease as malignancy, vasculitis, trauma or hyperviscosity states, which should be excluded.Treatment in the majority of the cases is symptomatic, but if it is secondary Mondor's disease, the underlying problem should be investigated. Physicians should be aware of this condition in order to address patient concerns and avoid unnecessary treatments or investigations.
