Cine-viewing of overlapping thin collimation images: an improved diagnostic tool in multislice helical CT of the bowel.

As compared to single slice helical CT, multislice helical CT does not only improve the quality of the individual images (in terms of slice sensitivity profile and image artifacts) and the range of scan coverage, it also enforces the CT postprocessing possibilities. The advantage of post-processing thin collimation bowel CT images with overlap and cine-viewing or paging is reported. The case report illustrates that cine-viewing of overlapping thin collimation images obtained with multislice helical CT, allows an excellent evaluation of the bowel loops resulting in the diagnosis of a perforated sigmoid carcinoma and its complications.

Traumatic pseudo-aneurysm and dissection of the thoracic aorta in the presence of an aberrant right subclavian artery: value of multi-slice helical CT.

A case of traumatic pseudo-aneurysm and dissection of the proximal descending thoracic aorta in association with an aberrant right subclavian artery and a common trunk for both common carotid arteries is presented. The diagnosis of this traumatic pseudo-aneurysm and dissection in association with these congenital anomalies by means of a multi-slice helical CT is discussed. To our knowledge, this is the first such case reported in the literature.

Mri findings in primary non-Hodgkin's lymphoma of the liver.

Primary lymphoma of the liver is a very rare malignancy. Most often, these lesions consist of diffuse large B-cell non-Hodgkin's lymphoma that occurs mostly in immunodeficient patients. To prove the primary nature of a hepatic lesion, a systemic lymphoproliferative disease should be ruled out. Secondary liver involvement during Hodgkin's and non-Hodgkin's lymphoma is frequent. In advanced cases the incidence varies from 25% to 50%. The present case describes the MRI features of a primary lymphoma of the liver presenting as a solitary nodule. The primary lymphoma presents as a T2-hyperintense homogeneous nodule, with a signal intensity comparable with the signal intensity of the spleen. Signal intensity is comparable on in and out of phase imaging. The nodule is slightly T1-hypointense and doesn't show any arterial contrast uptake. In the late venous phase a slight increase in signal intensity is noted. Two and a half minutes after the administration of contrast agent, the lesion is iso-attenuating with the liver parenchyma. This case is rare because of the concomitant presence of heterozygous sickle cell anaemia and the presence of Gamna-Gandy bodies in the splenic parenchyma. It remains uncertain whether the presence of the Gamna-Gandy bodies is associated with the liver lymphoma or with the underlying sickle cell anaemia, or with a combination of both.

Non-traumatic giant aneurysm of a superficial temporal artery.

We present a case of giant aneurysm in the superficial temporal artery. A 59-year-old male was admitted to our hospital with a slowly growing swelling just in front of his right ear. Diagnosis was made by US and CT. CTA was able to provide accurate anatomic information and to eliminate the risks associated with diagnostic conventional angiography. A superselective embolization of the giant temporal aneurysm was performed.

Omental infarction in childhood.

We present a case of right-sided omental infarction in a child documented with ultrasound and multislice computed tomography and confirmed by surgery and pathologic examination. Omental infarction is a rare cause of right-sided acute abdominal pain in a child. Differential diagnosis includes appendicitis. With different imaging modalities a diagnosis can be made and avoid unnecessary appendectomy.

Collision tumor in the ileum: a rare combination of an adenocarcinoma and small cell neuroendocrine tumor.

We present a case of a rare small bowel tumor. A 73-year-old female patient presented at our department with vague abdominal pain. Ultrasound examination discovered an inhomogeneous vascularised mass originating from a small bowel loop, mesenteric enlarged lymph nodes and a nodule in the liver. Multislice Computed Tomography of the abdomen confirmed the ultrasonographic findings and found omental implants together with a left-sided ovarian mass. Surgery was performed. Pathology revealed a rare ileal collision tumor consisting of an adenocarcinoma and a small cell neuroendocrine tumor with peritoneal metastasis of neuroendocrine origin and coincidental benign lesions on both ovaries.
