INTRODUCTION: Papillary intralymphatic angioendothelioma (PILA) is an exceptionally rare metastasizing soft tissue tumor. It tends to arise in the subcutaneous tissues of distal extremities in children. Only four intraosseous PILA cases have been reported until now in English language literature. CASE REPORT: We present a case of PILA arising in the distal femoral epiphysis of a 50-year-old female patient. It started as a relentless pain in her left knee. A plain radiography revealed a radiolucent area in the left internal femoral condyle...

Ankle fractures involving the distal fibula are common injuries. Malreductions and subsequent malunions of the distal fibula can result in worse clinical outcomes and posttraumatic arthritis. The ability to accurately evaluate and identify malreductions and malunions of the distal fibula is important. A number of different radiographic and CT measurements have been described to assess fibular length and rotation. This review highlights various radiologic measures and discusses their advantages and limitations...

Post-traumatic cortical cystic lesions are rare radiolucent lesions that appear as a complication of low-severity fractures in children. Their relevance lies in the fact that few cases of these lesions have been described to date, so they are little known among clinicians caring for children. Three case reports of well-circumscribed cortical lytic lesions detected at 2-4 months during the follow-up of non-displaced distal radius fractures in children aged 9, 7, and 2 years are presented. The consistent clinical history and typical radiological features allowed the accurate diagnosis of post-traumatic cortical cystic lesion, without the need for advanced imaging tests or biopsy...

Atraumatic muscle disorders comprise a very wide range of skeletal muscle diseases, including metabolic, inflammatory, autoimmune, infectious, ischemic, and neoplastic involvement of the muscles. Therefore, one must take clinical and laboratory data into consideration to elucidate the differential diagnoses, as well as the distribution of the muscle compromise along the body-whether isolated or distributed along the body in a symmetric or asymmetrical fashion. Assessment of muscular disorders often requires imaging investigation before image-guided biopsy or more invasive procedures; therefore, radiologists should understand the advantages and limitations of imaging methods for proper lesion evaluation and be aware of the imaging features of such disorders, thus contributing to proper decision-making and good patient outcomes...

Spinal involvement of infantile hemangiomas is rare with the predilection to involve the epidural space. A proper diagnosis might be challenging due to the atypical location and variable/inconsistent use of the International Society for the Study of Vascular Anomalies (ISSVA) classification by radiologists, pathologists, and clinicians. A proper diagnosis of epidural infantile hemangioma is key due to the different aggressiveness of the treatment options with inconstant literature regarding the best available treatment...
