Carotid sheath-like foreign body in the neck.

In otolaryngology practice, we see young children who have inserted a foreign body (FB), which is usually found at home, into their ears or nose. Uncommon complications of an ingested FB are penetration and migration into the neck. Interestingly, among such FBs, sharp fish bones are the most commonly observed in Turkey. In our patient, the FB caused deep neck infection because of FB reaction. In our patient, we could not find any clue of a FB during examination. We were able to see the FB by magnetic resonance imaging (MRI). Interestingly, the FB looked like a carotid sheath on the MR image.

CT and MR characteristics of hibernoma: six cases.

PURPOSE: The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of hibernoma. MATERIALS AND METHODS: We retrospectively evaluated imaging findings of CT and MR examinations of six patients (three men and three woman, aged 27-48 years) with histopathological diagnosis of hibernoma. RESULTS: On CT examination, the lesions were slightly hyperdense, and on T1- and T2-weighted MR images, they were isointense or slightly hypointense compared to the subcutaneous fat. All of these lesions showed contrast enhancement and one out of the six lesions had internal linear septations. CONCLUSION: Hibernoma has a wide spectrum of CT and MR imaging findings, which should be considered in differential diagnosis, especially with other lipomatous lesions.

Complete cleft sternum associated with clavicular hypoplasia and pectus excavatum.

A sternal cleft is a rare congenital and developmental disorder. In general, this disorder is associated with skeletal and extraskeletal abnormalities (eg, Cantrell syndrome), but isolated sternal clefts have also been reported. A sternal cleft with pectus excavatum is a rare congenital abnormality. We present a complete sternal cleft with right-sided clavicular hypoplasia and pectus excavatum in a 31-year-old female patient.

Cutting-balloon angioplasty in transplant renal artery stenosis as first-line treatment in the early postoperative period.

Percutaneous transluminal angioplasty has been successfully used for the treatment of transplant renal artery stenosis (RAS). Cutting-balloon angioplasty (CBA) is being used as a second option in pressure-resistant stenosis. It is thought that CBA is less traumatic and therefore restenosis occurs less frequently than in conventional angioplasty. This case report describes the unusual use of a cutting balloon in transplant RAS as a first option in the early postoperative period. Long-term follow-up data are also presented.

Final destination of an ingested needle: the liver.

Foreign body ingestion is a common problem in children, but it is also seen among adults. Most foreign bodies pass through the gastrointestinal tract without causing complications. Perforation of the gut by a foreign body, followed by migration of the foreign body to the liver is quite rare. Herein we report a case of inadvertent ingestion of a sewing needle that perforated the duodenum and migrated to the liver. The patient was monitored weekly with abdominal radiographs, but displacement of the needle could not be observed. At follow-up, right upper quadrant pain was noted. Two weeks later, computed tomography revealed that the needle was completely buried into the right lobe of the liver. Ultrasonographic examination successfully showed the extracapsular displacement of the needle. Eventually, laparoscopic removal of the needle was easily performed.

Prevalence of testicular microlithiasis in males with congenital adrenal hyperplasia and its association with testicular adrenal rest tumors.

BACKGROUND: Testicular microlithiasis (TM) is characterized by calcium deposits within the seminiferous tubules and is associated with benign and malign conditions. AIM: To determine TM prevalence in patients with congenital adrenal hyperplasia (CAH) and its association with testicular adrenal rest tumors (TART). PATIENTS AND METHODS: Scrotal ultrasound using a high-frequency linear transducer (12 MHz) was performed in 41 patients aged 12.1 +/- 4.7 (range 3.5-23.3) years and 49 healthy similarly aged controls. TM was classified with respect to the number of microliths per ultrasound field as limited (LTM, <5 microliths) and classic (CTM, > or = 5 microliths). CTM was graded as grade 1 (5-10 microliths), grade 2 (11-20 microliths), and grade 3 (>20 microliths). RESULTS: TM was detected bilaterally in 9 (21.9%) patients and 2 (4.1%) control cases (1 bilateral, 1 unilateral). Four patients had LTM, one evaluated as grade 1, one as grade 2, and three as grade 3. There were 9 patients with TART. Four patients had TM and TART concomitantly. CONCLUSION: Because TM is frequently found in patients with CAH and may also exist concomitantly with TART, we recommend that these patients be followed annually by testicular ultrasound.

Severe spasm of the renal artery after blunt abdominal trauma simulating end-organ infarction.

Traumatic occlusion of the renal artery is a serious injury. Management differs according to the grade of injury. In most circumstances, emergency surgical revascularization or endovascular intervention is required. We describe the case of a child with multiorgan injuries and spasm of the main renal artery after blunt trauma simulating arterial occlusion or end-organ infarction.

MR imaging features of ventricular noncompaction: emphasis on distribution and pattern of fibrosis.

OBJECTIVE: The purpose of this study is to describe morphologic features and delayed contrast-enhancement pattern of the noncompaction of the left ventricle in cardiac magnetic resonance (MR) imaging. METHODS: We retrospectively reviewed morphological cardiac MR imaging findings of ventricular noncompaction in 15 patients (eight men, seven women, and ages 6 months to 73 years old, mean 22 year). In 10 patients delayed contrast enhanced images were obtained after the morphological examination. RESULTS: In all patients, noncompaction was seen in the apical and midventricular-lateral segment. Basal-septal segment involvement was not determined in any patients. Noncompacted/compacted ratio was 2-4.5 (mean 3). In nine patients, right ventricular involvement was observed in addition to left ventricular noncompaction. Delayed contrast-enhancement was seen in eight out of 10 patients not only involved segments but also normal segments of the heart. CONCLUSION: Cardiac MR imaging is a valuable imaging method in patients with suspected ventricular noncompaction by showing increased trabeculations, deep intertrabecular recesses and fibrosis. Fibrosis is a common finding in ventricular noncompaction.
