Substantial interreader agreement for biopsy with reduction in biopsy rate: A multireader diagnostic performance study of ACR TI-RADS.

Purpose: To assess diagnostic performance of ACR TI-RADS in thyroid cancer detection and evaluate interobserver agreement among radiologists with lower interpreting experience.

Methods: Four radiologists retrospectively assessed 295 biopsied thyroid nodules from ultrasound studies performed between 2009 and 2019, blinded to histopathology. Diagnostic performance for cancer detection was determined individually, and interobserver agreement among four readers was evaluated with Fleiss kappa coefficient (ⱪ).

A rare case of laryngeal cleft in association with VACTERL and malrotation.

We report a rare case of a neonatal girl who presented with coughing and dyspnea immediately after feeds. At birth, she was noted to have an imperforate anus with a posterior fourchette fistula from which she was stooling. Initial imaging with radiography showed a normal bowel gas pattern; however, lumbar vertebral anomalies were noted.

Childhood asymmetrical labium majus enlargement sonographic and MR imaging appearances.

Background: Childhood asymmetrical labium majus enlargement (CALME) has been described sparsely in recent surgery, pathology, pediatric and gynecology literature; however, no comprehensive description from a radiology perspective has been developed.

Objective: The purpose of this case series is to describe the imaging findings of CALME and to review the current understanding of this recently described clinical entity with regard to clinical presentation, pathophysiology, differential diagnosis and treatment options.

Materials And Methods: This is a retrospective analysis of 3 girls, ages 5-7 years, who presented for imaging evaluation with subsequent pathologically proven CALME.

Initial bladder closure of the cloacal exstrophy complex: outcome related risk factors and keys to success.

Purpose: This study examines a large single-institution experience with cloacal exstrophy patients, analyzing patient demographics and surgical strategies predictive of bladder closure outcomes.

Methods: One hundred patients with cloacal exstrophy were identified. Complete closure history including demographics, operative history, and outcomes was available on 60 patients.

Diagnosis of rare association of orthotopic multicystic dysplasia with crossed fused renal ectopia.

Orthotopic multicystic dysplastic kidney with crossed fused ectopia is a rare congenital anomaly. This congenital anomaly may give an appearance of a solitary kidney morphology during the initial imaging evaluation. A solitary kidney should be carefully evaluated for the presence of duplication, horseshoe configuration, or crossed renal ectopy.

Neuroimaging findings of retroclival hemorrhage in children: a diagnostic conundrum.

Background: Retroclival hemorrhage in children may occur in three compartments, namely epidural, subdural, and subarachnoid, frequently secondary to trauma. Retroclival epidural hematoma may be associated with ligamentous injury, which may further result in instability at the craniocervical junction. Retroclival subdural hematoma may indicate a sentinel event for traumatic injury elsewhere within the brain or posterior fossa.

Diagnosis and management of an isolated pediatric plexiform neurofibroma involving the hepatic and celiac plexus using multimodality approach: problem solving with diffusion-weighted magnetic resonance imaging.

Plexiform neurofibroma with involvement of the gastrointestinal tract is a very rare entity in children. Here, we present a rather unique case of a 9-year-old boy with no clinical signs or features of neurofibromatosis type 1. A periportal mass lesion was incidentally found after performing an ultrasound in this previously healthy child.

The bone scan.

Bone imaging continues to be the second greatest-volume nuclear imaging procedure, offering the advantage of total body examination, low cost, and high sensitivity. Its power rests in the physiological uptake and pathophysiologic behavior of 99m technetium (99m-Tc) diphosphonates. The diagnostic utility, sensitivity, specificity, and predictive value of 99m-Tc bone imaging for benign conditions and tumors was established when only planar imaging was available.
