Background: Necrotizing fasciitis (NF) is a rapidly progressive and life-threatening infection of the fascia and subcutaneous tissues. Early diagnosis and prompt surgical intervention are critical to reducing morbidity and mortality. This case report highlights the importance of point-of-care ultrasound (PoCUS) in the rapid diagnosis of NF.

Case Presentation: A 34-year-old male carpenter presented to the Emergency Department of Casey Hospital, with a 48-hour history of increasing swelling and pain in his right arm and chest. Two weeks prior, he sustained an open wound to his right wrist from a rusty nail. Initial management by his family doctor focused on musculoskeletal injury without antibiotics. On ED presentation, the patient exhibited signs of systemic infection and gross swelling of the right upper limb and chest. PoCUS demonstrated characteristic findings of NF, including cobble stoning and subcutaneous air with dirty shadowing, leading to an expedited surgical consultation and immediate intervention.

Management and Outcome: The patient underwent multiple debridements, antibiotic therapy, and hyperbaric oxygen therapy. Post-surgical rehabilitation showed substantial gains in function and mobility.

Discussion: This case underscores the crucial role of PoCUS in the early diagnosis and management of NF. PoCUS allows for rapid bedside imaging, enabling timely surgical consultation and intervention, thereby improving patient outcomes. The multidisciplinary approach, involving emergency physicians, surgeons, and intensivists, is essential for optimal management of NF.

Unilateral leg swelling poses a diagnostic challenge with a myriad of potential differential diagnosis, including deep vein thrombosis (DVT), Baker's cyst, and cellulitis. As some of these causes can be benign and easily treatable, other causes may be more severe and even life threatening. This article highlights the critical need for healthcare professionals to expand their differential diagnosis when common causes have been excluded, recognizing that some rare etiologies may signify severe underlying conditions. We present the case of a 55-year-old female with a two-month history of right leg swelling, initially attributed to erysipelas due to negative DVT findings. Upon closer examination, an abdomino-pelvic CT scan revealed diffuse peritoneal carcinomatosis, obstructing the right external iliac vein and elucidating the unilateral lower limb edema. This case focuses the importance of considering atypical causes, especially in patients with a history of cancer, and the potential life-threatening nature of rare etiologies. The article emphasizes the significance of a multidisciplinary approach, comprehensive laboratory assessments, and advanced imaging techniques in achieving accurate and timely diagnoses, ultimately guiding effective patient management.
