Head CT in centenarians: emergency and non-emergency findings.

INTRODUCTION: Our retrospective study evaluates head CTs performed in our Hospital in the last 11 years (2009-2019) in centenarian patients. OBJECTIVES: To estimate the correlation between reasons for examination and CT findings in emergency and to evaluate if there was the expected involution of the brain by analyzing some non-emergency neuroradiological parameters (NENP). MATERIAL AND METHODS: 62 Head CTs performed on patients aged 100 and over were reviewed. They were evaluated emergency CT findings and NENP (leukoencephalopathy, enlargement of the ventricular volume, presence of vascular calcifications). For comparison, NENP were also assessed in two relatively younger populations of 62 patients aged between 65-70 (called "65-70") and 85-90 ("85-90"). RESULTS: In cases of suspected traumatic brain lesions, 11.9% (n = 5/42) of centenarians showed a cerebral bleeding; as concerns suspected stroke we found a higher concordance between clinical suspicion and CT features, 46.6% (n = 7/15). As regards NENP, no significant differences were found with respect to the "85-90" population in terms of severity of leukoencephalopathy, enlargement of the ventricular volume and presence of vascular calcifications. CONCLUSIONS: In emergency, CT plays a pivotal role in defining an immediate diagnosis and from a medico-legal point of view, resulting together with clinical observation the main strategy in the management of centenarians. By the analysis of NENP we may support that centenarians' brains on CT are similar to those of "85-90".

Horseshoe adrenal gland associated with spinal and vascular anomalies.

Horseshoe (or butterfly) adrenal gland (HAG) is an exceedingly rare congenital abnormality compared to horseshoe kidney. Here we present computed tomography findings of HAG in a 70-year-old man, associated with some spinal and vascular abnormalities; in addition, a brief review of HAG in adult people is presented. In our case, spinal anomalies included a severe scoliosis, a "butterfly" deformation of Th9 vertebra and the presence of a "split lumbosacral thecal sac" at L5 level. As regards, vascular anomalies, they were noted: the origin of the left common carotid artery from the innominate artery and the absence of celiac trunk with separate origin of three branches directly off the aorta (a splenic artery, a left gastrohepatic trunk and a right hepatic-pancreaticoduodenal artery).

Post-Traumatic Intracranial Dislocation of Unfractured Mandibular Condyle.

We present a case of post-traumatic intracranial dislocation of an unfractured mandibular condyle in a 17-year old female patient associated with multiple skull base fractures. Computed tomography (CT) findings are illustrated, and also postoperative CT is described. The article underlines the pivotal role of CT in the early diagnosis and in the investigation of additional brain lesions and complications.

Imaging findings of ovarian leiomyosarcoma with histopathologic correlations.

Leiomyosarcoma (LMS) is a malignant mesenchymal tumor deriving from smooth muscle. Ovarian LMS is exceedingly rare and only few reports have been reported in literature. The article illustrates a case of ovarian leiomyosarcoma in a 61-year-old woman, describing CT and MRI features correlated to histopathologic findings. LMS should be included in the differential diagnosis of solid and multiloculated ovarian lesions, in particular in post-menopausal women.

Traumatic peroneal split lesion with retinaculum avulsion: Diagnosis and post-operative multymodality imaging.

Tears of peroneus brevis tendon represent a cause of underdiagnosed lateral ankle pain and instability. The typical clinical presentation is retro-malleolar pain, in some cases associated with palpable swelling around the fibular malleolus, pain during activities and difficulty in walking. We present a case of peroneus brevis split lesion with superior peroneal retinaculum avulsion in a young athlete who referred to the emergency ward of our hospital for left ankle pain after an inversion injury. An early diagnosis allowed treating the injury and promptly resuming sport activity, after rehabilitation training. Surgical reconstruction key-points and post-surgical follow-up were also discussed. A late diagnosis would have caused a symptomatology worsening and an increased recovery time.

Nerve ultrasound in emergency room: a case of traumatic ischiatic nerve neurotmesis.

A 22 years-old-man was admitted to emergency after trauma. He suffered multiple deep cuts on his left leg. A lesion of the ischiatic nerve was suspected, and an ultrasound (US) evaluation was requested to confirm it. The study was conducted in the emergency room using a linear ultrasound transducer of 6-15 MHz and demonstrated the completely truncation of the ischiatic nerve (neurotmesis - Sunderland Grade V) with the proximal end retracted up to about 3cm from the edge of the wound. It was a very useful information for the neurosurgeon who after performed an end-to-end neurorrhaphy with suturation of perineurium. This short report underlines the importance of US, that thanks to its high spatial resolution and its time- and cost-effectiveness, can be considered a very important tool for the physician in emergency room to characterize peripheral nerve lesions.

Percutaneous treatment with radiofrequency ablation of varicose veins recurring after vein stripping surgery A preliminary study.

AIM: The aim of our study was to evaluate the efficacy of a new treatment of recurrent varicose vein after stripping of the great saphenous vein with rigid radiofrequency needles. MATERIAL OF STUDY: 37 patients enrolled (11 males and 26 females). 10 patients had recurrent varicose veins for the presence of residual reflux in the Saphenous-Femoral Junction (SFJ) stump, whilst 21 patients for the presence of a single or multiple re-chanalized and refluxing perforator veins, and 6 had mixed rechanalization due to perforator veins and refluxing saphenous stump. All patients have been treated by percutaneous ultrasound-guided obliteration with radiofrequency needles. Treatment efficacy have been assessed by US evaluation, and/or the appearance of recurrent varicose veins and classified as REVAS questionnaire. Follow up has been carried out at 30, 60, 180 days and 1 year after treatment. RESULTS: A complete obliteration of the perforator(s) stump(s) was observed in 12 procedures immediately after the treatment, and confirmed at 30 and 60 days. In 1 case (7.69 %) obliteration was not complete at 60 days. After 1 year of follow-up 3 perforators (23.07%) showed an incomplete or failed obliteration. A complete obliteration of the treated SFJ was observed in 27 cases at the end of the procedure and confirmed after 60 days of follow-up patients (Fig. 4). In 2 cases (6.89%), obliteration was non complete at 60 days. After 1 year of follow up 5 treated SFJ (17.24%) stumps showed an incomplete or a failed obliteration. DISCUSSION: Results show a reduction of the number of limbs affected by ulcer, skin pigmentation and stasis eczema, demonstrating correction of haemodynamic overload to be effective. CONCLUSIONS: This treatment is a new and effective solution to the problem of post-stripping recurrent varicose veins. KEY WORDS: Perforator veins, Radiofrequency, Recurrent post-stripping varicose veins, Saphenofemoral stump.
