Clinical imaging

Solitary vertebral chordoma presents as an intra- and extraosseous tumour with typical bright signal on T2-weighted images and moderate inhomogeneous enhancement on T1 postcontrast images. The diffusion weighted imaging (DWI) characteristics of this histologically proven third lumbar vertebra chordoma are reported for the first time. The DWI hyperintensity with increased apparent diffusion coefficient (ADC) values strongly supports the preoperative diagnosis of a vertebral chordoma, allows for careful preoperative planning of the surgical procedure, and helps to narrow the differential diagnosis.

Popliteal artery entrapment syndrome (PAES) is a rare congenital vascular pathology caused by the compression of the popliteal artery by adjacent muscle and tendinous structures. Popliteal artery aneurysm associated with this syndrome is extremely rare. ⋯ The patient was further evaluated with multidetector computed tomography angiography (MDCTA). MDCTA revealed PAES due to compression of the accessory fibers of the gastrocnemius muscle and related thrombosed popliteal aneurysm.

Review Case Reports
Inadvertent insertion of a nasogastric tube into the brain: case report and review of the literature.
The inadvertent insertion of a nasogastric tube (NGT) into the brain of a trauma patient with skull base fractures is reported. A 52-year-old male with head trauma was referred following a car accident with an NGT in situ. ⋯ The NGT was immediately removed manually. The patient finally went through neurosurgical operation because of an extradural hematoma, with normal postoperative course and outcome.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare disorder that is being diagnosed more frequently with the increasing availability of advanced imaging and more accurate histopathology. It occurs most commonly in nonsmoking, middle-aged women. ⋯ It is important to recognize this condition as it is considered a precursor of peripheral carcinoid tumors. This article will present a case of this uncommon condition with review of the literature, imaging findings, and clinical presentation.

Review Case Reports
Sequestrated thoracic disc herniation mimicking a tumoral lesion in the spinal canal--a case report.
Calcified thoracic disc sequestration is a very rare disease. Unusual sequestered disc fragments mimic spinal tumors and other space-occupying lesions due to a lack of discernible clinical features that can be used to differentiate these disc fragments from disc herniations and tumoral lesions. In this report, we describe a patient with a dorsally sequestrated calcified disc fragment in the thoracic spine that mimicked a bony tumoral lesion of the spinal canal and present a literature review. Thoracic disc sequestration accompanied by an atypical location requires a systematic diagnostic approach involving accurate preoperative history and careful radiographic evaluation.
