Abstract:
Multiple biliary hamartoma (MBH) is a rare cause of multiple benign hepatic lesions. The condition is also known as von Meyenburg complexes, multiple bile duct hamartomas and biliary microhamartomas. MBH is asymptomatic and usually found incidentally where it is important to differentiate from other causes of multiple liver lesions particularly liver metastases. Histologically, they consist of cystic dilatation of the bile duct, encompassed by fibrous stroma. We reported a 74 year old male patient with multiple hepatic lesions which ultrasonographic appearance suggested multiple hepatic cysts. The diagnosis of MBH was made by MRCP of whole abdomen. Recognition of this unusual lesion is essential to avoid confusion with other cystic tumors of the liver specially liver metastases and to learn more about its natural history and response to treatment.Pulse Vol.9 January-December 2016 p.60-63

Abstract:
AbstractVon Meyenburg complex is a benign biliary hamartoma observed in approximately 3% of the autopsies conducted. These hamartomas are small, multiple and can be seen anywhere in the liver. There is usually no abnormality in liver function tests, and the patient is mostly asymptomatic. They serve as a diagnostic dilemma, particularly during metastatic workup in suspected cancer patients. Imaging studies are usually noncontributory, and biopsy is necessary for a definite diagnosis. We present here a middle-aged North Indian male who underwent liver biopsy to rule out metastasis.

Abstract:
Brunner’s gland hamartoma (or Brunneroma) is an uncommon tumour with an incidence of <0.01%, accounting for approximately 5–10% of benign duodenal tumours. Usually asymptomatic, it may manifest occasionally with duodenal obstruction or upper gastrointestinal haemorrhage and rarely with biliary fistulation, cholestatic jaundice and intussusception. It may be associated with uraemia and chronic pancreatitis. The diagnosis is usually confirmed by imaging studies and upper gastrointestinal endoscopy. Surgical excision or endoscopic resection is preferred for symptomatic large hamartomas. Here we report a case of 45-year-old man presenting with features of pancreatitis and gastric outlet obstruction due to a large Brunner’s gland hamartoma, on his endoscopic, radiologic, surgical and pathologic findings.

Abstract:
Brunners gland hamartoma, also known as Brunneroma, is a rare, non-cancerous tumor that represents about 5–10% of benign duodenal growths, with an incidence of less than 0.01%. Most cases remain silent, causing no symptoms, but in some instances, they can lead to duodenal obstruction, upper gastrointestinal bleeding, or, more rarely, complications such as biliary fistulation, cholestatic jaundice, or intussusception. Diagnosis is primarily based on imaging techniques and upper gastrointestinal endoscopy. When these hamartomas grow large and cause symptoms, treatment typically involves surgical or endoscopic removal. Here, we present the case of a 50-year-old man with no known medical history who developed symptoms of gastric outlet obstruction. He was diagnosed with a sizable Brunners gland hamartoma and successfully treated with surgery.

Abstract:
Radiological imaging plays a pivotal role in the comprehensive management of liver tumors, encompassing diagnosis, treatment planning, and monitoring of therapeutic responses. Key imaging modalities utilized include ultrasonography (USG), computed tomography (CT), and magnetic resonance imaging (MRI), each offering distinct advantages and applications. Ultrasonography (USG): Ultrasonography is widely employed due to its accessibility, real-time imaging capabilities, and cost-effectiveness. It is particularly valuable for monitoring benign liver lesions and for guiding interventions such as biopsies. However, its utility can be limited by operator-dependent variability, challenges in obese patients, and interference from bowel gas. USG is less effective in characterizing atypical liver tumors, necessitating complementary cross-sectional imaging for comprehensive evaluation. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI): CT and MRI are indispensable for detailed characterization of liver lesions, leveraging multi-phase contrast-enhanced imaging to highlight vascular and structural features. In CT imaging, the arterial, portal venous, and equilibrium phases provide sequential insights into contrast uptake and washout patterns within tumors. MRI, particularly with hepatocyte-specific contrast agents like gadoxetic acid, enhances hepatocellular uptake visualization, aiding in the differentiation of hepatocellular carcinoma (HCC) from benign lesions and metastases. Benign Liver Tumors: Benign liver tumors include hemangiomas, focal nodular hyperplasia (FNH), hepatocellular adenomas (HCA), lipomas, angiomyolipomas, biliary hamartomas, and biliary cystadenomas. Each tumor type exhibits characteristic imaging features on CT and MRI, such as enhancement patterns, signal intensities on T1-weighted and T2-weighted sequences, and specific contrast agent uptake behaviors. Malignant Liver Tumors: Malignant liver tumors encompass primary hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), metastases from various primary sites, hepatoblastoma, hepatic angiosarcoma, epithelioid hemangioendothelioma (EHE), and embryonal sarcoma. These tumors present with distinct radiological characteristics, including vascular enhancement patterns, signal intensities on MRI sequences, and specific imaging findings such as ""wash-in/wash-out"" patterns in HCC and ""hypovascular"" features in ICC. Clinical Implications and Advances: Recent advancements in imaging techniques have significantly improved the sensitivity and specificity of liver tumor diagnosis. Techniques such as diffusion-weighted imaging (DWI) provide additional insights into tumor cellularity and microstructural properties, enhancing diagnostic accuracy. Moreover, the integration of advanced imaging protocols and contrast agents has enabled precise treatment planning and monitoring, ultimately improving patient outcomes. In conclusion, radiological imaging remains indispensable in the multidisciplinary approach to liver tumors, facilitating early detection, accurate diagnosis, and tailored treatment strategies based on comprehensive tumor characterization.

Abstract:
Abstract Benign liver tumours are commonly identified and usually asymptomatic, however, upon discovery, may pose a challenge in characterization and management. Cavernous haemangioma is the most common benign liver tumour. It may present in various sizes and numbers and if significantly large can cause clinical symptoms due to thrombosis, rupture, and haemorrhage. Among the benign tumours of hepatocellular origin, hepatocellular adenoma and focal nodular hyperplasia are frequently seen in young females, with the former having variants which carry the potential for malignant transformation. Biliary hamartomas and focal fatty lesions are often encountered intraoperatively and may be misconstrued as malignant deposits. Due to their byzantine clinical behaviour, a thorough knowledge of the vast array of benign liver tumours and their aetiopathogenesis is sine qua non for management.
