A case of an adult intussusception secondary to a fibroid polyp of the terminal ileum is reported. Adult intussusceptions are observed rarely, usually caused by an organic lesion. The preoperative diagnosis is based on US patterns, target aspect and sandwich sign.
Lymphadenopathy is a very common finding during the course of Whipple's disease (W.D.). Abdominal (mesenteric and retroperitoneal) tumoral lymphnodes may mimick malignant neoplasm, specially a lymphoma. The authors report the case of a patient who had an abdominal computer-assisted tomography (C.T.) at the diagnosis and during an eleven month survey for W.D. General C.T. findings can help to differenciate mesenteric lymphadenopathy in W.D. from those found in malignant lymphomas: low density (10-20 Hounsfield Units) because of the high fatty charge of Whipple's lymphnodes, lymphadenopathy in the lower mediastinum, progressive but slow improvement with antibiotic therapy.
From a series of 6,573 echographic surveys of pelvis in male and female, the authors point out 789 liquid images among them 82 are non gynecologic lesions. A statistical study of the different observed etiologies is proposed and compared with those of the literature. The main cases observed are gathered under several items: abscess, hematomas, urinary, digestive and vascular images and studied semiologically. The discussion points out the low frequency in opposition to the etiological diversity of this type of image and precise the diagnostic procedures rules which include other imaging methods especially computed tomography.
The authors report the case of an IgA secreting multiple myeloma which, after a rapid initial remission, relapsed with skin, thyroid, testis and lung metastases without bone recurrence. A review of the medical literature on this subject underlines the poorly differentiated microscopic appearance and the low secretion of paraprotein of these extraosseous plasmacytic tumours which have a poor prognosis due to their increased malignancy.
An echographic study of the fetal normal kidney in 274 fetuses (548 kidneys measured) from 15 to 40 weeks of pregnancy is proposed by the authors. This work includes morphologic and biometric study with the growth curves of 4 parameters. It is shown that both kidneys are morphologically similar and their growth is continuous and there is a constant ratio between the different parameters. Ratios are established: Length/BPD = 0,45 +/- 10%, Width/BPD = 0,27 +/- 10%, Thickness/BPD = 0,26 +/- 10% which are very useful for the echographist. One hopes that with morphologic and biometric criteria of normality, the early detection of urinary tract malformations will be easier.
