Diagnosis and management of a rare case of clival chordoma in a young male patient.

Chordomas are uncommon bone slow-growing tumors developing from remnants of the notochord. They are typically seen in adults, and rarely in children. We present the case of a 16-year-old male patient with a clival chordoma, presenting with progressive headache and diplopia. In this case report we aim to provide an educational explanation of the radiological findings, diagnostic challenges, and therapeutic and management strategies.

Bilateral renal hemorrhage in an anticoagulated patient: A rare case of Wunderlich syndrome.

We describe a rare case of Wunderlich syndrome with bilateral renal hemorrhage in a patient under anticoagulant therapy for atrial fibrillation. An 84-year-old woman came to our department complaining of acute bilateral flank pain. Clinical and laboratory examinations revealed a condition of hypovolemic shock. An abdominal contrast-enhanced CT scan detected the presence of a bilateral hemorrhage affecting the peri- and para-renal spaces. Planning an appropriate management strategy considering the anticoagulated treatment required a multidisciplinary approach in the case of the Wunderlich syndrome diagnosis.

An aggressive soft-tissue sarcoma of the extremity: A myxofibrosarcoma, grade 3 (FNCLCC system).

We report a case of myxofibrosarcoma of the posterior region of the femur, part of the group of soft-tissue sarcomas: a set of rare and heterogeneous tumors with various subtypes and different prognostic. It is characterized by local infiltrative activity and an extremely high rate of local recurrence. A 58-year-old man came to the Radiology Department to examine a voluminous round and expansive formation of the posterior thigh region. The patient stated that the mass had grown suddenly for about 3 months, maybe after a trauma, increasing in volume exponentially and causing him discomfort, embarrassment, and pain. The result of the first diagnostic approach, with the US, was unexpected and suspicious, and the radiologist wanted to do first a CT, and then maybe plan an MRI. The CT revealed an inhomogeneous density formation and in MRI the mass resulted to be compatible, with the radiologic pattern, with the diagnosis of a sarcoma of the soft tissue. The physicians had already alerted the pathological anatomy, as they suspected something malignant. So, some days after the MRI examination, the patient underwent histological sampling, confirming the suspicion: a myxofibrosarcoma (stage III) of the posterior region of the femoral region. The patient started on radio and chemotherapy, which increases survival and in the hope of reducing the size of the mass, and a strict follow-up was posed before doing the surgery.

Hereditary multiple exostoses with a giant osteochondroma degenerated into chondrosarcoma.

We present a case of hereditary multiple exostoses with malignant transformation to chondrosarcoma in a woman complaining of enlargement and pain in the right thigh. Hereditary multiple exostoses is a rare genetic disorder characterized by multiple osteochondromas. Malignant transformation to chondrosarcoma of a pre-existing osteochondroma is a possible significant manifestation of this hereditary syndrome. Imaging modalities such as X-ray, Ultrasound, and computed tomography play a crucial role in the diagnosis and management of these patients, as described in this case.

A remarkable case report of an interrupted inferior vena cava with hemiazygos and transhepatic continuation.

Inferior vena cava (IVC) interruption with azygos/hemiazygos continuation is an extremely uncommon congenital vascular anomaly, which may present with multiple variants. As a result, it is challenging to find in the literature the same anatomical variant. We report a unique case of an interrupted IVC with hemiazygos and transhepatic continuation in an 83-year-old female patient. The case was evaluated by performing Computed Tomography (CT) as imaging modality, with a multiphase protocol, able to detect accurately this complex vascular anomaly. The purpose of this case report is not only to present this remarkable case but also to briefly show the types of interrupted IVC, starting from the anatomy and the embryology of the IVC and the azygos system, and to discuss the value of imaging in detecting the vascular anomaly.

A rare case of siliconomas resulting from free silicone injections in breast tissue.

One of the most common complications of free silicone injection at multiple sites is its leakage and more rarely its migration through the lymphatic system with a resulting local inflammatory reaction of granulomatous type, known as "siliconoma". This report describes the case of a young woman who came to our attention for bilateral mastodynia and palpable tumefactions in breast and gluteal region, a few years after percutaneous injections of free liquid silicone for breast augmentation.
