Cavernous malformation of the III cranial nerve: A challenging pathology

We present the case of a 69 years-old man, with an insidious and progressive palsy of the III left CN with 6 months of evolution. CT scan revealed a 1,2 cm lesion located at the suprasellar and pre-pontine cistern at the free edge of the tentorium, initially compatible with the diagnosis of a small meningioma. He was submitted to surgery but surprisingly histopathological analysis revealed a cavernous malformation, intrinsic to the nerve.This is the twelfth reported case of an III cranial nerve CM, and the management of this lesions still doesn't have clear and definitive recommendations regarding treatment. In selected cases, the lesion can be excised without compromise of the affected cranial nerve, but when complete excision is compromised, the surgeon has to decide between function sacrifice or leaving a residual behind, knowing that this last decision can lead to recurrence and further morbidity.

We describe a case of aggressive progression of TA in an infant. This child was the youngest to be affected with the disease as reported in the literature. A 3.5-month-old boy presented with cyanosis of both legs, tachycardia and antithrombin III deficiency. Computed tomography angiography (CTA) revealed thrombosis of distal aorta and both iliac arteries. Thrombectomy was performed at the level of both common femoral arteries. In addition, thigh amputation of the left leg had to be performed. TA was diagnosed postmortem with thrombosis of the distal aorta, its branches and upper mesenteric artery which was not occluded on ...

This study sought to derive and validate a systematic method enabling AVC quantification using computed tomography angiography (CTA) in patients with AS.Methods134 consecutive patients with AS who underwent both NCCT and CTA were included in the study and sub-divided into derivation (n=71) and validation cohorts (n=63). On NCCT, AVC was quantified using Agatston method utilizing the software developed for semi-automatic assessment of coronary calcium. On CTA, mean contrast attenuation of aorta (AortaHU) and standard deviation (SD) was measured in the region-of-interest at level of sinotubular junction.ResultsUsing an adjus...

Clinical scores have been proposed to stratify the risk of pulmonary thromboembolism (PTE), although this approach suffers a low specificity and the unavoidable need for computed tomography pulmonary angiography (CTPA) scans.

The recommended imaging tests for nonatherosclerotic peripheral artery disease include ultrasound duplex Doppler (ultrasound), intravascular ultrasound (inside arteries), MR angiography (MRA; MRI of arteries with or without intravenous [IV] contrast dye), CT angiography (CTA; CT scan of arteries using IV contrast), arteriography (x-rays of arteries with IV contrast).

Abstract Pulmonary embolism (PE) is a condition characterised by an obstruction of the pulmonary arterial system by one or more emboli. Advanced clinical practitioners are often faced with ruling out a diagnosis of PE in patients with non-specific symptoms such as dyspnoea and pleuritic chest pain, which can be fairly mild and therefore a diagnosis of PE easily missed. PEs can be a challenge to diagnose, especially in elderly people, since it can be difficult to differentiate their symptoms from other less serious illnesses. Widely used scoring tools are helpful to calculate a patient's probability of having a PE....

Conclusions Spectral photon-counting CT allowed for the noninvasive evaluation of ISR with reliable results regarding the residual lumen for most tested stents and the clear identification or suspicion of stenosis for all stents. In contrast, the residual lumen could not be detected for a single stent using DLCT.

Authors: Gitsioudis G, Nunninger M, Missiou A, Wolf P, Katus HA, Korosoglou G Abstract Background: Non-invasive computer tomography (CT)- and magnetic resonance (MR)-based cardiac imaging still remains challenging in rodents. To investigate the robustness of non-invasive multimodality cardiac imaging in rabbits using clinical-grade CT and MR scanners. Methods: A total of 16 rabbits (2.7-4.0 kg) serially underwent cardiac-gated imaging using a clinical-grade 256-row CT and a 1.5 Tesla MR-scanner at baseline and at 4-month follow-up (16±1 weeks). Image analysis included image quality (5-grade scale), left ...

ConclusionAdding CTP and/or a delayed-phase CTA to NCCT with arterial-phase CTA improves the decision-maker ’s confidence level and creates a trend towards a lower threshold for mechanical thrombectomy.

We present a case of a 23-year-old male, who had sustained multiple injuries following a road traffic accident. Computed tomography scan revealed a large retroperitoneal hematoma, and active contrast extravasation was noted in the retroperitoneum adjacent to the bare area of the liver and right adrenal gland. After a trial of initial conservative management, he had expanding retroperitoneal hematoma with dropping hemoglobin. Angiography showed posttraumatic aneurysm from the adrenal artery that was successfully embolized with microcoils. As blunt adrenal gland trauma is rare, a high degree of clinical suspicion is required...
