Caustic ingestion: CT findings of esophageal injuries and thoracic complications

2020

Ingestion of caustic substances, whether accidental or for the purpose of suicide, can cause severe lesions of the lips, oral cavity, pharynx, upper gastrointestinal system, and upper airways. In particular, caustic agents could be responsible for severe esophageal injuries resulting in short- and long-term complications. Because of these important clinical implications, timely diagnosis and appropriate management are crucial. In the evaluation of esophageal injuries, thoraco-abdominal computed tomography (CT) is preferable to endoscopy as it avoids the risk of esophageal perforation and allows the evaluation of esophageal injuries as well as of the surrounding tissue. In this review, we re…

Review: Neuroradiological aspects of infantile spasms

1987

With the modern noninvasive brain imaging methods, cerebral lesions of different types and degrees can frequently be determined in infants with West syndrome. In CT examinations preceding the spasms and the ACTH therapy, "idiopathic" forms of infantile spasms were rare. The CT findings consistent with perinatal or postnatal encephalopathy were more frequent than those found with embryonic or fetal lesions alone. The fact that pathognomonic changes cannot be determined, may reflect the low specificity of CT diagnosis in infants with chronic CNS diseases. A slight and mostly transient enlargement of CSF spaces during ACTH therapy is a probable side-effect of the medication. In infants with pe…

Hamartoma of the urinary bladder: case report and review of the literature.

1999

Bladder hamartoma is a rare benign entity with only eight cases reported in the literature thus far, and whose general imaging features have not, to our knowledge, been previously discussed. The purpose of this report is to review the literature and to discuss the imaging findings in one case of bladder hamartoma where US features were those of an inhomogeneous solid mass with an unechogenic center, which was in accordance with the CT findings of a soft tissue mass with central inhomogeneous enhancement due to central necrosis.

Presacral Myelolipoma

2014

Many reports have described adrenal myelolipomas but there have been only a few reports of extra-adrenal myelolipomas. We describe a 74-year-old woman who came to our observa- tion for MRI of the lumbar spine for typical lumbar back pain. In addition to signs of mild scoliosis and spondylo disc arthrosis, MR imaging revealed a presacral mass showing a heterogeneously high signal in all pulse sequences and almost completely suppressed on inversion recovery sequences for fat tissue. CT imaging confirmed the fatty nature of the lesion and no signs of bone involvement. These findings were most consistent with a diagnosis of a rare presacral myelolipoma as confirmed at histopathologic analysis. …

B‐Mode ultrasonography of the paranasal sinuses compared with CT findings

1992

Ultrasound as a diagnostic aid in the evaluation of the sinuses has been a controversial issue. Sensitivities have been reported from 29% to 100% and specificities from 55% to 99%. These wide variations in results from previous studies may have resulted from technical differences. However, the "gold standard" most often used for comparison has been a Water's view radiograph, which has been shown to correlate poorly with intraoperative and CT scan findings. To our knowledge, no one in the English language literature has evaluated sonography of the sinuses with computed tomography as the gold standard. In addition, evaluation of the ethmoid sinus has been neglected by previous studies that ha…

Automatische Klassifikation der Lebersegmente nach Couinaud: Entwicklung eines neuen Algorithmus und Evaluierung an Spiral-CT-Datensätzen

2003

Purpose: To develop a software tool that analyzes the anatomy of the portal vein branches and assigns segmental and subsegmental branches according to Couinaud's classification system and to evaluate its accuracy. Materials and Methods: The algorithm was developed in C++ on a PC. The algorithm recognizes the three major branching patterns of the portal vein. Segmental and subsegmental branches are assigned to 8 segments following Couinaud and encoded by 8 colors. The software was evaluated using CT data sets of 39 patients. After the individual segmental anatomy of each patient was determined by an experienced radiologist, automatic classification was performed and the results were compared…

Subcutaneous rupture of hepatic hydatid cyst: CT findings.

2006

Structured reporting of CT scans of patients with trauma leads to faster, more detailed diagnoses: An experimental study.

2021

This study aimed to determine whether structured reports (SRs) reduce reporting time and/or increase the level of detail for trauma CT scans compared to free-text reports (FTRs).Eight radiology residents used SRs and FTRs to describe 14 whole-body CT scans of patients with polytrauma in a simulated emergency room setting. Each resident created both a brief report and a detailed report for each case using one of the two formats. We measured the time to complete the detailed reports and established a scoring system to objectively measure report completeness and the level of detail. Scoring sheets divided the CT findings into main and secondary criteria. Finally, the radiological residents com…

Carcinoma Uroteliale in Cisti Pielogena

2013

Urothelial carcinoma in a pyelocaliceal cyst Renal complex cysts are lesions whose nature can be either benign or malignant. Depending on the presence of septa, solid components, enhancement or calcifications, they are distinguished according to the Bosniak classi- fication based on CT findings, as well as MRI and ETG. We report a rare case of urothelial carcinoma, originating over a pyelocalyceal cyst in a 50-year-old man, and classified as Bosniak IIF by CT and MRI investigations.
