Sensitivity of CT, MRI, and EUS-FNA/B in the preoperative workup of histologically proven left-sided pancreatic lesions

Abstract 99mTc bone scintigraphy(BS) is still the most widely used method to evaluate bone metastasis in China. The aim of this study was to investigate the necessity of the 99mTc bone scintigraphy in the preoperative workup for patients with potentially resectable esophageal squamous cell cancer (ESCC,cT1-4aN0–3). Methods This was a prospective cross-section clinical trial (ChiCTR1800020304). There were a total of 471 patients who were diagnosed ESCC in Thoracic Surgery Clinic from October 2018 to September 2020. Of these 471 patients, 385 patients with cT1-4aN0–3 who were potentially candidates for surgical resection were consecutively enrolled into the study. BS was performed preoperatively. The treatment strategy could be changed if the bone metastasis was confirmed. The primary endpoint was the incidence rate of the treatment regimen being changed because of bone metastasis. The secondary endpoint was the rate of positive BS findings. Results In all 385 patients, there are only 2(0.5%) patients changed their treatment regimen because of bone metastasis proved by BS. The rate of positive BS findings is 1%. The number of patients with false positive and false negative was 2(0.5%) and 2 (0.5%), respectively. The BS diagnostic performance for bone metastasis was as follows: sensitivity, 50%; specificity, 99.5%; positive predictive value, 50%; negative predictive value, 99.5% and accuracy, 99.0%. There were no significant difference of bone metastasis among the Age, Sex, Tumor location and Clinical stage. Conclusion 99mTc bone scintigraphy is unnecessary in the preoperative workup for patients with potentially resectable esophageal squamous cell cancer.

Axial Mass

Medulloblastoma is a common paediatric posterior fossa tumour typically presenting as midline intra-axial mass involving the cerebellar vermis and/or roof of fourth ventricle with typical radiological features. These can be extra-axial in extremely rare instances with less than 50 cases reported so far in literature. We present a case of 18-year-old boy presenting with ataxia and headache. MRI showed dural mass (involving the left tentorium cerebellum) with typical imaging features of extra-axial lesion. The patient underwent near total excision of the tumour. Histopathology along with immunohistochemistry revealed the mass to be medulloblastoma. We present this case to highlight rarity of this location for medulloblastoma and the importance of considering this in the differential diagnosis of atypical posterior fossa extra-axial lesions. This can help in performing other relevant preoperative workup similar on the lines of medulloblastoma and planning of relevant management.

Preoperative Workup

Cystic lesions of the pancreas are identified with increasing frequency by modern imaging. The mucinous cystic neoplasm (MCN) is treated with resection for its malignant potential. How much preoperative evaluation is needed before undertaking operation is frequently a diagnostic dilemma. A retrospective review of 32 patients who underwent resection of a MCN between 1994 and 2007 was performed to define the preoperative evaluation and operative treatment of MCN patients. Thirty-two patients (30 women; mean age 49) had histology-proven MCN. Twenty-seven patients had symptomatic cysts (84%). Five had a history of gallstones and/or acute pancreatitis. All patients were worked up with CT and/or MRI. Endoscopic ultrasound was performed in 14 (44%) and endoscopic retrograde cholangiopancreatography in six (18%). Cytology was obtained in 13 (40%). Pathology revealed 22 benign MCNs (68%), five malignant MCNs (16%), and five MCNs with borderline pathology. Preoperative workup including CT or MRI imaging and cytology suggested MCN as the lesion in 15 patients (46%). CT features by itself predicted MCN in three patients (9%). Cytology revealed another six patients (19%) with possible MCN. In this series, preoperative workup did not identify three of five patients with MCN malignancy. A preoperative diagnosis cannot be made in most patients with MCN. Operative treatment can be based on clinical presentation and CT imaging because endoscopic ultrasound and fine needle aspiration for evaluation may be misleading. Middle-aged women with cystic lesions in the tail of the pancreas without prior gallstone or pancreatitis history most typically fit the profile of the MCN patient.
