BACKGROUND: Percutaneous access to the vertebral bodies is commonly done via the transpedicular approach for both diagnoses and treatment of spinal pathology. While this approach is effective in most cases, it is difficult in certain situations such as a patient with obstructing hardware from prior surgery. OBJECTIVES: To investigate and illustrate an alternative to the typical percutaneous access to the vertebral body via an extrapedicular approach and to determine the complications associated with this approach...

PURPOSE OF REVIEW: The possibility of complete recovery for a lung cancer patient depends on very early diagnosis, as it allows total surgical resection. Screening for this cancer in a high-risk population can be performed using a radiological approach, but this holds a certain number of limitations. Liquid biopsy could become an alternative and complementary screening approach to chest imaging for early diagnosis of lung cancer. RECENT FINDINGS: Several circulating biomarkers indicative of lung cancer can be investigated in blood, such as circulating tumor cells, circulating free nucleic acids (RNA and DNA) and proteins...

BACKGROUND: The reports on disseminated candidiasis in dogs so far describe at least one predisposing factor. This case report, however, highlights candidiasis in a dog without any known predisposition. PATIENT: A 1.5-year-old intact female Hovawart dog was presented with subcutaneous nodules and polyuria/polydipsia. An excisional biopsy revealed a chronic pyogranulomatous and necrotizing inflammation with mycotic structures. The patient became febrile and lethargic, and developed lameness...

: The aim of this case report is to be aware of occult carotid lesions in thoracic- abdominal trauma because, carotid artery injury consequent to blunt trauma is rare, affecting less than 1% of patients as reported in literature. A 45-years-old female, involved in a traffic accident, arrived to Emergency Room hemodynamically stable, with a Glasgow Coma Scale of 15, complaining abdominal pain, without any neurological signs. She underwent Computed Tomography (CT) scan that showed a complete disruption of left abdominal wall muscles, associated with massive bowel loops herniation...

We present the case of a 43-year-old lady who presented with headaches, visual impairment, and seizures, progressing rapidly over the course of a few weeks. Extensive workup excluded an inflammatory or infectious cause. Imaging studies revealed diffuse thickening of the leptomeninges and serial CSF analysis showed raised opening pressures and increased protein levels. A diagnostic biopsy of the lower thoracic dura confirmed the diagnosis of primary diffuse leptomeningeal gliomatosis (PDGL). She was managed supportively for her symptoms and unfortunately she passed away a few weeks later...

In 2009-2014, dose surveys aimed to collect adult patient data and parameters of most common radiographic examinations were performed in six Russian regions. Typical patient doses were estimated for the selected examinations both in entrance surface dose and in effective dose. 75%-percentiles of typical patient effective dose distributions were proposed as preliminary regional diagnostic reference levels (DRLs) for radiography. Differences between the 75%-percentiles of regional typical patient dose distributions did not exceed 30-50% for the examinations with standardized clinical protocols (skull, chest and thoracic spine) and a factor of 1...

When confronted with various findings on thoracic radiographs, fourth-year veterinary students often have difficulty generating appropriate lists of differential diagnoses. The purpose of this one-group, pretest, posttest experimental study was to determine if a game could be used as an adjunct teaching method to improve students' understanding of connections between imaging findings and differential diagnoses. A novel board game focusing on differential diagnoses in thoracic radiography was developed. One hundred fourth-year veterinary students took a brief pretest, played the board game, and took a brief posttest as a part of their respective clinical radiology rotations...

Pulmonary ground-glass opacity (GGO) has raised increasing attention of clinical oncologists and thoracic surgeons in recent years. GGO appears as hazy increased opacity of lung, with preservation of bronchial and vascular margins. GGO is less opaque than consolidation, in which bronchovascular margins are obscured. In most cases, GGOs are indolent, while in other cases, they may grow malignant. This pattern makes it difficult to find a standard way to treat patients with GGO. Moreover, with the improvement of technology, more and more GGOs are found in patients' computed tomgraphy (CT) scan, making it a global problem...

MATERIAL AND METHODS: A case of 60-year-old woman with idiopathic syringomyelia and progressive myelopathy by dorsal arachnoid web is discussed. One focal indentation along the dorsal surface of the spinal cord at the T3 vertebral body level revealed the scalpel sign, a radiologic entity diagnostic of a dorsal thoracic arachnoid web. RESULTS: T2-T3 laminectomy for the resection of dorsal arachnoid band was performed. Careful sectioning of the web resulted in visual apparent relief of the compression and good functional recovery...

BACKGROUND: Previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. We were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles. METHODS: We retrospectively identified all patients with a clavicle fracture between July 2001 and October 2013 in two level 1 trauma centers. Patients aged 18 years or greater with an acute unilateral clavicle fracture and a chest CT scan in the supine position displaying both clavicles and the complete fracture were included...

PURPOSE: Cobalt chromium (CoCr) rods have recently gained popularity in adolescent idiopathic scoliosis (AIS) surgical treatment, replacing titanium (Ti) rods, with promising frontal correction rates in all-screw constructs. Posteromedial translation has been shown to emphasize thoracic sagittal correction, but the influence of rod material in this correction technique has never been investigated. The aim of this study was to compare the postoperative correction between Ti and CoCr rods for the treatment of thoracic AIS using posteromedial translation technique...

BACKGROUND CONTEXT: Many radiological parameters have been reported to correlate with patient's disability including sagittal vertical axis (SVA), pelvic tilt (PT), and pelvic incidence minus lumbar lordosis (PI-LL). European literature reports other parameters such as lumbar lordosis index (LLI) and the global tilt (GT). If most parameters correlate with health-related quality of life scores (HRQLs), their impact on disability remains unclear. PURPOSE: This study aimed to validate these parameters by investigating their correlation with HRQLs...
