Jejunal intussusception on jejunostomy tube: A rare cause of occlusion in adults.

INTRODUCTION: Acute intestinal intussusception (AI) in adults secondary to jejunostomy is a rare complication and a surgical emergency requiring early diagnosis and treatment. PRESENTATION OF CASE: We report the case of a 44-year-old patient, without medical history, who presented dysphagia after caustic ingestion. The patient underwent a Witzel feeding jejunostomy. The evolution was marked by the installation of abdominal distension with vomiting and alteration of the general state, the diagnosis of an intussusception in the jejunostomy tube was made in the abdominal CT scan, which required a surgical intervention, and reduction of intussusception, with simple after effects. DISCUSSION: Acute intestinal intussusception (IIA) secondary to jejunostomy tube placement is a rare abdominal emergency. It manifests with signs of upper gastrointestinal obstruction. Diagnosis is based on abdominal imaging by ultrasound or CT scan. Treatment is most often surgical (Chavrier et al., 1992) [1]. CONCLUSION: We present a very rare example of acute intestinal intussusception in adults, complicating jejunostomy, with non-specific clinical signs, which needed an early radiological diagnosis for adequate management.

[Myositis ossificans circumscripta: a case report]. / La myosite ossifiante circonscrite: à propos d'un cas.

Myositis ossificans circumscripta is a benign lesion characterized by focal heterotopic soft tissue ossification, occurring in young people generally after localized trauma. Clinical and radiological appearances may mimic a sarcomatous neoplastic process. We report a case of myositis ossificans occurring after trauma, so as to illustrate the different imaging features of this benign pathology on conventional radiographs and computed tomography.

[Occipital osteosarcoma of a 33 years old man: a case report]. / Ostéosarcome occipital chez un homme de 33 ans: à propos d'un cas.

Cranial localization of osteosarcoma is rare, representing only 0,7-3% of cranial primary tumours. The authors present the case of a 33 year old man with occipital osteosarcoma diagnosed by CT scan, MRI and angiography. The radiological features of this pathology are discussed.

[Intracerebral chondrosarcoma in a 12 year old child]. / Chondrosarcome intracérébral frontal chez un enfant de 12 ans.

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.

Intracaval Migration of Ureteral Stent.

Ureteral stents have proven to be an invaluable tool for endourologists. Morbidity is minimal, but complications do exist. Up to 3 months complications are not frequent, but longer indwelling times are associated with increasing frequency of incrustation, infections, secondary stone formation, obstruction of the stented tract and migration. We report a rare case of a 33 year old pregnant patient with migration of an ureteral endoprosthesis. The patient received a right ureteral stent at 12 weeks for acute obstructive pyelonephritis. When her urologist tried to remove the ureteral stent post delivery, the stent was not found in the bladder. Ureteroscopy was performed but no ureteral stent was found. The patient showed a moderate improvement of the pyelonephritis, but complained about insidious palpitations. A CT scan was performed and showed the presence of the ureteral stent extending from the inferior vena cava up to the right atrium. Endovascular retrieval was performed through a puncture of the common femoral vein, using a curved guide that was introduced through the vena cava into the right atrium. Under fluoroscopic control, it was twisted around the stent and pulled out. The outcome was favorable, and no other complications were noted.

[Pneumoblastoma in an adult: a case report]. / Pneumoblastome chez l'adulte: cas clinique.

Pneumoblastoma of the adult is rare. It presents more often as a large heterogenous and peripheral parenchymal mass. In this case, chest radiographs showed a small homogeneous mass in the right lung apex. The solid nature but non-specific appearance of the mass was confirmed at CT. The histological diagnosis was obtained from surgical biopsy. The interest of this observation is the rare occurrence of the lesion in adults and the atypical imaging features in this patient.

[Hydatid disease of the urinary bladder: a case report]. / Kyste hydatique de la vessie. A propos d'un cas.

All organs in the human body may be affected by hydatid disease. Urinary tract involvement in hydatid disease is not common, corresponding to only 2-4% of cases. The kidneys are the most commonly affected organs in the urinary tract. We report a case of hydatid cyst of the urinary bladder.

[The piriformis syndrome: a rare cause of non discogenic sciatica. A case report]. / Le syndrome du muscle pyramidal: une cause rare de sciatique non discale.

Atypical sciatic pain without apparent discogenic origin should raise the possibility of a non-discogenic etiology, especially tumoral but also infectious or inflammatory. We report the case of a young patient presenting with non-discogenic S1 radiculopathy due to sciatic nerve involvement in the subpiriformis canal secondary to piriformis muscle inflammation. The authors review technical considerations and results of MRI which is of great value in the evaluation of piriformis muscle pathology.

[CT and MRI features of spinal hydatidosis. A report of 8 cases]. / Hydatidose rachidienne, aspects scanner et irm. A propos de 8 cas.

PURPOSE: Hydatidosis affects the bone in 0.5 to 2% of cases, with 44% of these cases involving the spine. We report 8 cases of vertebral involvement evaluated by CT and/or MRI. Materials and Methods. This retrospective study from January 1996 to August 2000 included seven patients (5 men and 3 women) aged between 28 and 65 years old. The mean age was 45 years old. Five patients underwent CT scan (one by CT-myelography). MRI was available in 4 cases. RESULTS: Imaging showed multicystic bony lesions. Thoracic involvement was present in 4 cases, lumbar involvement in 2 cases, and sacral involvement in 2 cases. The process involved 2 adjacent vertebrae in 4 cases at the thoracic and lumbar levels and the entire sacrum in the other cases. Only one case of vertebral collapse was noted, but extension into the spinal canal was noted in all cases. Other sites of involvement were also noted, especially in adjacent soft tissues, liver and spleen. CONCLUSION: The presence of multicystic vertebral lesions with involvement of adjacent soft tissues and/or distant organs should raise the possibility of spinal hydatidosis in endemic countries.
