The 19Th Century

Septic pelvic thrombophlebitis (SPT) was initially diagnosed and described in the late 1800's. The entity had a high incidence and mortality during this period of time, and a surgical therapeutic approach was the treatment of choice. Since then, the diagnosis, incidence, and management of the entity evolved. This evolution followed the development of newer diagnostic tools such as computed tomography (CT), magnetic resonance imaging (MRI), and a better understanding of the pathophysiology of the disease. The treatment of SPT has had significant changes as well, from a surgical approach at the end of the 19th century to a medical approach after the 1960's. By using an adequate broad-spectrum antibiotic therapy, mortality has decreased. However, controversy in the management of this entity remains even till today.

Abstract Background Pancreatic cystic lesions are increasingly identified in persons undergoing abdominal imaging. Serous cystic neoplasms (SCNs) have a very low risk of malignant transformation. Resection of SCNs is not recommended in the absence of related symptoms. The accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) to identify SCNs is not known and may impact clinical care. Aims To evaluate the accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) for the diagnosis of SCN. To see how this can impact the decision to resect suspected SCNs. Methods Retrospective cohort study of patients from the University Health Network with suspected SCNs from 2017–2020 who underwent either a CT or MRI of the abdomen. Reports noting pancreatic cystic lesions were identified and reviewed. Only cases with suspected SCNs were included. Clinical (age, sex, symptoms, treatment) and radiographic (type of imaging, reported cyst characteristics) data was collected. Pathology was reviewed for all cases where the cysts was biopsied or resected during follow-up. The gold standard for the diagnosis for SCN was pathology of resected specimen or EUS-guided biopsy cytopathology showing no evidence of a mucinous lesion, CEA level below 10ug per L and amylase level below 50 U/L. Results 163 patients were included in the study. 99 (61%) were female and 98 (60%) underwent CT scan. EUS-guided biopsy was performed in 24 (15%) of patients and 8 (5%) had surgical resection. Multidisciplinary review was performed in 6 of the 8 cases that went to surgery. Of the resected specimens, 5 (63%) were SCN, 1 was a mucinous cystic lesion, 1 was a neuroendocrine tumor and 1 was a carcinoma. Two patients underwent EUS evaluation prior to surgical resection. In one case SCN was resected when EUS reported an undetermined cyst type. Reasons for surgical resection were: the diagnosis of serous cyst was not definitive (n=5), symptoms (n=2), and high-risk mucinous cystic neoplasm identified on EUS (n=1). Of 30 patients with pathology available, 15 (50%) were confirmed to have a SCN. CT and MRI had a sensitivity, specificity, positive predictive value and negative predictive value of 93%, 25%, 52% and 80%, respectively. Conclusions Surgical resection for SCN lesions is driven by diagnostic uncertainty after cross-sectional imaging. Multidisciplinary review and EUS evaluation may improve diagnostic accuracy and should be considered prior to surgical resection of possible SCN lesions. Funding Agencies None

Computed tomography (CT) and magnetic resonance imaging (MRI) are enabling more precise diagnosis and treatment planning in patients with diseases of the larynx. The aim of this article is to describe the role of these methods in assessment of the laringeal diseases and key local anatomic characteristics important for spread of the disease. CT and MRI have a valuable contribution to the staging of the tumors due to the possibility to show the relationship to the ventricular complex, involvement of the subumucosal spaces, defining craniocaudal and anterposterior extension, laringeal cartilage invasion, as well as regional lymph node metastases.

Cases of neurogenic stuttering have been reported in the literature throughout the past century. Site(s) of lesion(s) have been documented usually by association of symptoms, EEG studies and occasionally by computed tomography (CT). The authors present three cases in which the site(s) of lesion(s) are documented by CT, magnetic resonance imaging (MRI) and SPECT. This study supports previous findings of neurogenic stuttering following either bilateral diffuse lesions or a unilateral lesion. In at least one case, the actual site of the lesion would have been missed without the use of SPECT testing. EEG studies were not helpful in identifying the site of the lesion.

AbstractThe obliteration of the frontal sinus via an osteoplastic approach is performed with the aim of achieving a permanent ‘switching off’ by final and conclusive clearing out. For this, freshly harvested abdominal fat has shown itself to be the best clinically. It is possible to demonstrate the vitality of fat transplanted into the frontal sinus without an operation i.e. by a macroscopical and histological examination using magnetic resonance imaging (MRI). The magnetic resonance examinations were carried out on a supraconductive 0.5 T Magnet (Gyroscan T.S.II, Philips Medicine Systems, Eindhoven, Netherlands) with a quadrature (square) head spool. We produced T1-weighted spin echo images (TR: 450–550 ms; TE: 20–25 ms), T2-weighted fast spin echo images or in double-echo technique in transverse orientation (Turbo SE or TR: 2000–2500 ms; TE: 50–90 ms) and short tau inversion recovery (STIR) sequences for fat suppression (TJ: 140 ms; TR: 1400 ms; TE: 30 ms). The fat implanted into the frontal sinus of 11 patients aged 22–65 years, having undergone an osteoplastic frontal sinus operation with obliteration, was examined post-operatively by MRI. Objectives were the time-dependent distribution of portions of vital fatty or connective tissue, the eventual development of necroses or cysts as well as recurrences, inflammatory complications or re-epithelization of the frontal sinus four to 24 months postoperatively. In only six out of 11 cases was vital fatty tissue found. Fatty necrosis occurred five times, whereas in four cases a transformation into granulation tissue and in one case into connective tissue could be seen. All 11 patients were complaint-free. Long-term observations are needed to see if differences in the recurrence rate of frontal sinus disease are dependent on whether the implanted fat remains vital or necrosed and transformed.
