Plantar fibromatosis, or Ledderhose disease, is a rare hyperproliferative disorder of the plantar aponeurosis. It may occur at any age, with the greatest prevalence at middle age and beyond. This disorder is more common in men than woman and it is sometimes associated with other forms of fibromatosis. Diagnosis is based on clinical examination. Ultrasound (US) and magnetic resonance imaging (MRI) can be useful to confirm the diagnosis. A 44-year-old man with Ledderhose disease who underwent ultrasound and MR is described in this paper.

The Nutcracker Syndrome is a rare and often unrecognized cause of chronic pelvic pain and left back pain. These symptoms are due to the left renal vein compression between the aorta and the superior mesenteric artery (anterior nutcracker) or between the aorta and the spine (posterior nutcracker). The variety of clinical manifestations make the diagnosis difficult and commonly delayed. Therefore, imaging plays a key role in correcting the diagnosis by confirming the left renal vein stenosis and ruling out any differential diagnosis. Treatment options are discussed by a multidisciplinary team involving urologists, nephrologists and vascular surgeons for each patient. We report the case of 2 patients presenting chronic pelvic and lower back pain in whom clinical investigation and CT imaging findings were consistent with a nutcracker syndrome.

Verrucous carcinoma (VC) is an unusual, well differentiated, and low-grade type of squamous cell carcinoma, characterized by benign histology and cytology but markedly invasive clinical behavior. They have a predilection for squamous mucosae, particularly those of the head and neck region. Many factors have been associated with its pathogenesis, including the presence of previous skin lesions; VC arising from a prosthesis injury is rare. Here we reported a case of VC of oral cavity a particularly very aggressive, arising from prosthesis injury. Regardless of the treatment modality, given new insights into the possible aggressivity of this tumor, radiotherapy associated to chemotherapy may be a more appropriate primary treatment compared with the significant local morbidity associated with surgery.

Hepatic metastases from carcinoid tumours are typically solid, hypervascular lesions on imaging. The cystic form, mimicking an abscess, is extremely rare. We report a case of a 48-year-old female presenting with a large hepatic mass that was diagnosed as a hepatic abscess, but the ultrasound-guided biopsy showed well-differentiated grade 1 neuroendocrine tumour. CT scan of chest, abdomen and pelvis was performed, looking for the primary tumour, it revealed an endobronchial mass of the right inferior lobe. Lung biopsy by rigid bronchoscopy was taken confirming the diagnosis of a typical carcinoid tumour.

Kienböck disease is a condition characterized by avascular necrosis of the lunate bone. Advanced imaging can aid in the diagnosis and staging of Kienböck disease. Magnetic resonance imaging (MRI) is an important adjunct to diagnosis. In particular, MRI is helpful early in the disease when plain radiographs may not reveal abnormalities. A 17 -year-old man with Kienböck disease who underwent radiography and MR is described in this article.

Introduction: Vascular rings, due to the double aortic arch, are a class of congenital anomalies, considered as an important cause of tracheoesophageal compression. These anomalies are usually symptomless and thus are diagnosed fortunately when imaging is being performed for other reasons. Case Report:We report a clinical case of a patient with a history of dysphagia in his childhood, never labeled or treated. Conclusion:Currently, advanced imaging, especially computed tomography (CT), is the diagnostic procedure of choice of the double aortic arch. It can be associated with other anatomical variants. Surgical repair leads to excellent long-term prognosis.

Muscle metastases remain rare as a secondary localization for cancers in general and lung cancer in particular. They are discovered incidentally in most cases and in the advanced stages of cancer. We report the case of a 60-year-old man, followed for squamous cell carcinoma, who was found to have muscle metastases during the follow-up of associated muscle pain. This case highlights the existence of these metastases in lung squamous cell carcinoma, rare as it is, and requires particular attention from practitioners in the follow-up of patients to detect these cases as early as possible and improve patient survival. Computed Tomography (CT) remains an excellent exam for the detection of skeletal metastasis.
