[Imaging of pancreatic and hepatic tuberculosis in an infant presenting with jaundice]

The incidence of abdominal tuberculosis has increased over the last decade and can mimic any other disease. Pancreatic involvement is an uncommon cause of jaundice in children. A case of obstructive jaundice due to pancreatic tuberculosis in an infant, with hepatic involvement is reported. The sonographic and computed-tomographic features are described.

Syndrome de Lemierre : à propos d’une observation pédiatrique

We report a case of Lemierre syndrome with extensive thrombophlebitis of the internal jugular and subclavian veins with multiple septic emboli to the lungs and pericardium. This report illustrates a case of this forgotten disease in a child and the unusual presence of pericardial involvement.

[Intracerebral chondrosarcoma in a 12 year old child]

Chondrosarcoma is a rare cartilaginous tumor, representing less than 0,5% of intracranial tumors. This tumor occurs primarily in elderly patients and involves long and pelvic bones. The authors report a case of intracerebral chondrosarcoma in a 12 year old child, probably fronto-ethmoidal in origin. CT and MR imaging showed a lytic partly calcified soft tissue mass.

[Non-Hodgkin lymphoma of the calcaneus and ovary in an infant]

The authors report a case of non-Hodgkin lymphoma with involvement of the calcaneus and ovary in a 4 year- old girl. Calcaneal involvement by this tumor is unusual and ovarian involvement is infrequent.

[A rare cause of spinal cord compression: osteochondroma of the thoracic spine. A case report]

Osteochondroma or exostosis is the most common benign tumor of bone, but vertebral involvement is rare. The authors report the case of a 16 years old male with a family history of hereditary multiple exostoses who presented with spinal cord compression. MR examination showed an intraspinal extradural bone lesion at the T1-T2 level, hyperintense on T1 weighted and hypointense on T2 weighted images, causing marked cord deformity. The CT scan showed a tumor of the body and left pedicle of T2 with severe narrowing of the spinal canal.

[Tuberculosis of the posterior vertebral arch. A case report]

Tuberculosis of the spine usually involves the vertebral body and intervertebral disk. Involvement of the posterior arch is rare. We report a case of tuberculosis involving the posterior elements of the T4 and T5 vertebrae in a 38 year old woman. CT is helpful to assess bony structures whereas MRI is ideal to evaluate the neural structures. Clinical, radiographic, and therapeutic considerations regarding tuberculosis of the spine are reviewed.
