Tuberculose pancréatique : une cause rare d’ictère pseudo-néoplasique par compression de la voie biliaire principale

Exceptional association of hepatic and pancreatic tuberculosis mimicking metastatic pancreatic neoplasia: A case report and review of the literature

Introduction

Despite the high prevalence of tuberculosis in the world and especially in endemic areas such as Morocco, isolated hepatic and pancreatic tuberculosis and pancreatic tuberculosis remain rare and pose a real diagnostic problem.

Case presentation

We report a case illustrating an exceptional association of pancreatic tuberculosis with hepatic tuberculosis in a 44-year-old immunocompetent woman, in whom the presence of a pancreatic mass on imaging suggested a neoplastic origin. The diagnosis was rectified after bacteriological and pathological study of the CT-guided percutaneous biopsy specimens.

Discussion

The symptomatology of pancreatic and hepatic tuberculosis is unspecific and polymorphic and can mimic any intra-abdominal pathology. Abdominal ultrasound is often the first imaging modality used. The diagnosis of certainty is bacteriological.The treatment of pancreatic and hepatic tuberculosis is identical to the other extrapulmonary tuberculosis. the anti-bacillary drugs are the gold standard. Surgery is reserved for complicated forms.

Conclusion

The diagnosis of hepatic and pancreatic tuberculosis is a challenge for the clinician. The treatment is usually medical and based on antituberculosis treatment; surgery may be necessary in case of complications.

Tuberculosis (TB) of the Porta Hepatis Presenting with Obstructive Jaundice Mimicking a Malignant Biliary Tumor: A Case Report and Review of the Literature

Localized hepatobiliary tuberculosis (TB) is a rare disorder which can present with an obstructive jaundice mimicking other noninfectious causes such as cholangiocarcinoma. Here, we report a case of porta hepatis tuberculosis in 19-year-old female who presented with an obstructive jaundice, and her computed tomography (CT) of the abdomen revealed a hepatic hilar mass with radiological features mimicking a malignant biliary tumor. We also review the literature related to this disorder.

Tuberculous lymphadenitis as a cause of obstructive jaundice: A case report and literature review

Obstructive jaundice secondary to tuberculosis (TB) is extremely rare. It can be caused by TB enlargement of the head of the pancreas, TB lymphadenitis, TB stricture of the biliary tree, or a TB mass of the retroperitoneum. A 29-year-old man with no previous history of TB presented with abdominal pain, obstructive jaundice, malaise and weight loss. Ultrasonography (US), computer tomography (CT) scan and endoscopic retrograde cholangiopancreatography (ERCP) were suggestive of a stenosis of the distal common bile duct (CBD) caused by a mass in the posterior head of the pancreas. Tumor markers, CEA and CA19-9 were within normal limits. At operation, an enlarged, centrally caseous lymph node of the posterior head of the pancreas was found, causing inflammatory stenosis and a fistula with the distal CBD. The lymph node was removed and the bile duct resected and anastomosed with the Roux-en Y jejunal limb. Histology and PCR based-assay confirmed tuberculous lymphadenitis. After an uneventful postoperative recovery, the patient was treated with anti-tuberculous medication and remained well 2.5 years later. Though obstructive jaundice secondary to tuberculous lymphadenitis is rare, abdominal TB should be considered as a differential diagnosis in immunocompromised patients and in TB endemic areas. Any stenosis or fistulation into the CBD should also be taken into consideration, and biliary bypass surgery be performed to both relieve jaundice and prevent further stricture.

[Pancreatic tuberculosis: an unusual cause of obstructive jaundice accessible to endoscopic management]

Tuberculosis of the pancreas is unusual and often secondary to generalized tuberculosis. In most cases clinical presentation is obstructive jaundice due to pancreatic mass lesion. Although diagnosis is usually obtained after resection of the mass lesion, endoscopic procedures might avoid non-necessary surgical procedure. We report a clinical case of pancreatic tuberculosis diagnosed by endoscopic ultrasound guided fine needle aspiration biopsy and treated by biliary stenting.

Pancreatic and peripancreatic diseases mimicking primary pancreatic neoplasia

A variety of anatomic variants and pathologic conditions in and around the pancreas may simulate primary pancreatic neoplasia at routine abdominal cross-sectional imaging. An ambiguous lesion whose appearance suggests a pancreatic origin requires a broad differential diagnosis that can subsequently be narrowed on the basis of both clinical history and features at optimal computed tomography (CT) and magnetic resonance (MR) imaging. Pancreas-specific multidetector CT and MR imaging techniques with thin collimation, multiplanar and multiphasic scans, and newly introduced curved planar reformation may help avoid potential diagnostic pitfalls. These techniques can help identify and characterize a mass in multiple viewing planes, thereby helping distinguish a true pancreatic neoplasm from peripancreatic adenopathy or from a tumor of the adjacent duodenum or small bowel. They can also help determine the cause of a tumor. It is important that the radiologist be familiar with the wide spectrum of anatomic variants and disease entities that can mimic primary pancreatic neoplasia in order to initiate the appropriate lesion-specific work-up and treatment and avoid unnecessary tests or procedures, including surgery.
