Primary cranial vault lymphoma with extra- and intracranial extension in an immunocompetent patient is extremely rare. Given its rarity, the optimal management of this entity remains uncertain. We report an atypical case of a 21-year old immunocompetent man, who presented with an 8-month history of enlarging parieto-occipital mass. CT and MR imaging revealed a large mass with extra cranial and cranial components with sagittal sinus involvement. Unusually, angiography showed a significant tumor blush with large feeding vessels. After a pre surgical embolization, the patient underwent a complete tumor resection followed by radio and chemotherapy with satisfactory results.

Totally Implantable venous access insertion has become routinely involved in the treatment of patients in oncology, However, certain complications are associated with the use of these devices: catheter migration with embolization, pinch-off sign. We report a case of successful extraction of an embolized distal portion of the Catheter from left pulmonary artery.

Chordomas are rare bone tumors. They represent 2 to 3% of primary bone tumors, affecting the sacral parts in the majority of cases. They are characterized by their insidious evolution. Imaging plays an important role in the diagnosis, particularly with standard radiography and CT scans, allowing an optimal evaluation of bone involvement, while MRI specifies the degree of invasion of soft tissue and neighboring structures. Ultrasound is also used to guide biopsy procedures, and interventional radiology, through the combination of angiography and radiological embolization, can limit the risk of bleeding during surgery. We report two observations illustrating the role of radiology at the diagnostic and therapeutic level in two patients diagnosed with chordoma.

The Seldinger technique is the mainstay of vascular and other luminal access in interventional radiology. It provides a safe and simple way to access arteries, and the retrograde approach through the common femoral artery is the vascular radiologist’s basic approach serving both diagnostic and therapeutic roles in different patients. This technique is not without complications, and experience and improved equipment will undoubtedly eliminate this potential complication and prevent failure.
