1A 32-year-old asymptomatic woman undergoes an abdominal MRI for incidental liver lesion characterization. The dynamic study with hepatobiliary contrast (gadoxetate disodium / Primovist) demonstrates a 3.5 cm well-circumscribed lesion in segment IVa that shows intense, homogeneous arterial phase hyperenhancement, becomes isoattenuating on the portal venous phase, possesses a central T2-hyperintense scar with delayed contrast uptake, and exhibits iso- to hyperintensity on the 20-minute hepatobiliary phase. What is the most likely diagnosis?

A.Hepatocellular adenoma (HNF-1alpha inactivated)

B.Focal nodular hyperplasia (FNH)

C.Atypical cavernous hemangioma

D.Fibrolamellar hepatocellular carcinoma

Explanation: Focal nodular hyperplasia (FNH) is characterized by functional hepatocytes and malformed biliary ductules that retain hepatobiliary contrast agents such as gadoxetate disodium (Primovist) during the hepatobiliary phase (iso- to hyperintense). The classic central scar is hyperintense on T2-weighted images and demonstrates delayed contrast enhancement due to fibrous stroma. Hepatocellular adenomas typically lack functioning biliary excretion and appear hypointense on the hepatobiliary phase.

2Which of the following dynamic contrast-enhancement patterns on multiphasic CT or MRI is pathognomonic for a typical cavernous hepatic hemangioma?

A.Peripheral, discontinuous, globular nodular enhancement on arterial phase with progressive centripetal fill-in matching blood pool attenuation

B.Rapid, homogeneous arterial hyperenhancement with immediate portal venous phase washout and enhancing capsule

C.Peripheral rim-like arterial enhancement with progressive central necrosis and delayed capsular retraction

D.Homogeneous arterial enhancement with persistent central hypointense non-enhancing scar on delayed phases

Explanation: Typical hepatic cavernous hemangiomas demonstrate peripheral, nodular, discontinuous enhancement during the early arterial phase that mirrors aortic blood pool attenuation. Over portal venous and equilibrium/delayed phases, contrast progressively fills the lesion centripetally, remaining isointense to blood vessels without true washout.

3In a 58-year-old patient with hepatitis C cirrhosis undergoing surveillance, multiphasic contrast-enhanced CT reveals a 22 mm observation in segment VIII exhibiting non-rim arterial phase hyperenhancement (APHE), non-peripheral portal venous phase washout, and an enhancing capsule on delayed phase. According to the ACR/CBR LI-RADS v2018 classification, what is the correct categorization?

A.LR-3 (Intermediate probability of malignancy)

B.LR-4 (Probably HCC)

C.LR-5 (Definitely HCC)

D.LR-M (Probably or definitely malignant, not specific for HCC)

Explanation: Under LI-RADS v2018, an observation >= 20 mm in a high-risk cirrhotic patient demonstrating non-rim arterial phase hyperenhancement (APHE) along with at least one major feature (washout appearance or enhancing capsule) meets the criteria for LR-5 (Definitely HCC). Here, the lesion is 22 mm with APHE, washout, and an enhancing capsule, fulfilling definitive LR-5 diagnostic criteria with 95-100% specificity for hepatocellular carcinoma.

4Regarding the molecular and radiologic subtypes of Hepatocellular Adenoma (HCA), which subtype is associated with the highest risk of malignant transformation to hepatocellular carcinoma and frequently demonstrates nuclear beta-catenin activation on immunohistochemistry?

A.HNF-1alpha-inactivated HCA (H-HCA)

B.Inflammatory HCA (I-HCA)

C.Unclassified HCA (U-HCA)

D.Beta-catenin-mutated HCA (b-HCA, exon 3 mutation)

Explanation: Beta-catenin-mutated hepatocellular adenoma (b-HCA), particularly with exon 3 mutations, carries the highest risk of malignant transformation into hepatocellular carcinoma (up to 5-10% or more) and occurs with higher frequency in men and glycogen storage disease patients. In contrast, HNF-1alpha-inactivated adenomas have virtually no malignant potential and show marked diffuse steatosis (diffuse signal drop on chemical shift out-of-phase MRI).

5A 64-year-old man presents with dull right upper quadrant abdominal pain and weight loss. Abdominal CT shows a 6 cm solitary, ill-defined, non-encapsulated hepatic mass in the left lobe associated with capsular retraction, dilatation of distal intrahepatic bile ducts, and satellite nodules. Dynamic CT demonstrates thin peripheral rim enhancement during the arterial phase with progressive, persistent centripetal delayed enhancement. What is the most likely diagnosis?

A.Hepatocellular carcinoma

B.Mass-forming intrahepatic cholangiocarcinoma

C.Focal confluent fibrosis

D.Hepatic angiosarcoma

Explanation: Mass-forming intrahepatic cholangiocarcinoma (iCCA) typically presents as a large, scirrhous mass with peripheral arterial rim enhancement followed by progressive, persistent delayed enhancement due to abundant fibrous stroma. Key ancillary features include overlying liver capsular retraction, peripheral satellite nodules, and upstream biliary ductal dilatation.

6On contrast-enhanced abdominal CT, a pyogenic liver abscess frequently exhibits the 'double target sign'. Which pathological features produce this characteristic imaging finding?

A.A central non-enhancing fluid necrosis, an inner hyperenhancing inflammatory rim, and an outer hypoattenuating zone of perilesional parenchymal edema

B.An inner calcified fibrous capsule surrounded by a hyperdense rim of active arterial extravasation

C.A peripheral rim of dense calcification surrounding a central zone of liquefactive necrosis with gas-fluid levels

D.A central hypervascular nidus surrounded by a thick, avascular, mucin-filled pseudocapsule

Explanation: The 'double target sign' on contrast-enhanced CT represents a central non-enhancing necrotic/purulent cavity surrounded by an inner hypervascular enhancing capsule (granulation tissue) and an outer hypoattenuating halo of perilesional hepatic parenchymal edema. This appearance is highly suggestive of a pyogenic liver abscess.

7A 38-year-old woman with a history of antiphospholipid syndrome presents with acute right upper quadrant pain, rapid onset of ascites, and hepatomegaly. Contrast-enhanced CT reveals non-visualization and thrombosis of the right and middle hepatic veins, patchy peripheral parenchymal hypoattenuation on portal venous phase with intense arterial enhancement of the caudate lobe, and subsequent caudate lobe hypertrophy. What is the diagnosis?

A.Portal vein thrombosis (Pylephlebitis)

B.Sinusoidal obstruction syndrome (Veno-occlusive disease)

C.Budd-Chiari syndrome

D.Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu)

Explanation: Budd-Chiari syndrome results from hepatic venous outflow obstruction (thrombosis of the main hepatic veins and/or suprahepatic inferior vena cava). Because the caudate lobe (segment I) drains independently into the inferior vena cava via separate small emissary veins, it is preserved, undergoes compensatory hypertrophy, and shows marked hyperenhancement compared to the congested, hypoperfused peripheral liver ('flip-flop' perfusion pattern).

8According to the 2012 Revised Atlanta Classification for acute pancreatitis, what is the correct definition of a 'Pancreatic Pseudocyst'?

A.A non-encapsulated peripancreatic fluid collection occurring within the first 4 weeks of necrotizing pancreatitis

B.An encapsulated peripancreatic fluid collection with a well-defined non-epithelial inflammatory wall, occurring > 4 weeks after the onset of interstitial edematous pancreatitis and containing no necrotic debris

C.A thick-walled necrotic collection containing variable amounts of solid and liquid debris occurring > 4 weeks after necrotizing pancreatitis

D.A congenital cystic lesion lined by true mucin-producing cuboidal epithelium connected to the main pancreatic duct

Explanation: Under the Revised Atlanta Classification, a Pancreatic Pseudocyst is an encapsulated peripancreatic fluid collection with a well-defined non-epithelial inflammatory wall that develops > 4 weeks after the onset of interstitial edematous pancreatitis and contains exclusively liquid (no necrotic tissue). Encapsulated collections containing solid necrotic material developing > 4 weeks after necrotizing pancreatitis are termed Walled-Off Necrosis (WON).

9On contrast-enhanced multiphasic CT of the pancreas, what is the classic imaging appearance of a resectable pancreatic ductal adenocarcinoma located in the head of the pancreas?

A.A hypervascular mass during the arterial phase with intense central calcification and no biliary ductal dilatation

B.A multilocular macrocystic lesion with central sunburst calcification and hyperenhancing thick fibrous septa

C.An ill-defined hyperdense mass that enhances homogeneously on portal venous phase and displaces the portal vein anteriorly

D.A poorly defined, hypoattenuating/hypoenhancing scirrhous mass on the pancreatic parenchymal phase causing simultaneous dilation of both the common bile duct and the main pancreatic duct (double duct sign)

Explanation: Pancreatic ductal adenocarcinoma is typically a scirrhous, hypovascular tumor that appears hypoattenuating relative to the intensely enhancing normal pancreatic parenchyma on the pancreatic parenchymal phase (approx. 40-50 seconds post-injection). In the pancreatic head, it frequently obstructs both the common bile duct and the main pancreatic duct, creating the classic 'double duct sign'.

10Under the revised International Consensus (Fukuoka/Kyoto) Guidelines for the management of Intraductal Papillary Mucinous Neoplasms (IPMN) of the pancreas, which of the following is classified as a 'High-Risk Stigma' that warrants immediate surgical resection in a surgically fit candidate?

A.Enhancing mural nodule >= 5 mm, main pancreatic duct diameter >= 10 mm, or obstructive jaundice in a patient with a pancreatic head cystic lesion

B.Main pancreatic duct dilation between 5 and 9 mm in the absence of mural nodules

C.Cyst growth rate >= 2.5 mm per year with normal serum CA 19-9 levels

D.Cyst diameter >= 3.0 cm with thin unenhancing septa and no mural nodules

Explanation: According to the revised Fukuoka/Kyoto guidelines, 'High-Risk Stigmata' include: (1) obstructive jaundice in a patient with a cystic lesion of the pancreatic head, (2) enhancing mural nodule >= 5 mm on CT/MRI or EUS, and (3) main pancreatic duct diameter >= 10 mm. These features carry a high risk of invasive malignancy and warrant surgical resection without further delay in fit candidates.

Frequently Asked Questions

What is the format of the official CBR Título de Especialista em Radiologia examination?

The official CBR examination consists of two written multiple-choice stages: the 1ª Fase Prova Teórica (60 multiple-choice questions in 3 hours) testing fundamental concepts, physics, pathology, and clinical radiology; and the 2ª Fase Prova Teórico-Prática (60 image-based multiple-choice questions in 3.5 hours) evaluating interpretation of plain radiographs, ultrasound, CT, and MRI clinical cases. Note that the practical phase is a paper/computer-based image MCQ test, not an oral or hands-on patient station exam.

What is the passing score required by CBR and AMB?

Candidates must achieve a minimum score of 60.0% (at least 36 out of 60 correct) in the Prova Teórica AND a minimum score of 60.0% (at least 36 out of 60 correct) in the Prova Teórico-Prática. Failing either phase results in overall failure for that examination edition.

Is this practice bank an official test simulation?

No. This practice bank is an independent English-language MCQ study adaptation designed to help physicians and residents prepare for the CBR Título de Especialista em Radiologia e Diagnóstico por Imagem. All official Brazilian terms (CBR, AMB, CFM, CNRM, BI-RADS, PI-RADS, LI-RADS, SUS) are retained inline for authentic clinical context.

Are CBR Áreas de Atuação (subspecialties) included in this examination?

No. The CBR offers separate, dedicated certification examinations for specific Áreas de Atuação, such as Mamografia, Densitometria Óssea, Neurorradiologia Diagnóstica e Terapêutica, Ultrassonografia Geral e em Ginecologia e Obstetrícia, Ecografia Vascular com Doppler, and Radiologia Intervencionista. Those are distinct board exams with their own specific registration editais and candidate prerequisites.

How does obtaining the CBR specialist title grant the RQE in Brazil?

Upon passing the CBR/AMB examination, the candidate receives the Título de Especialista em Radiologia e Diagnóstico por Imagem issued jointly by AMB and CBR. The physician then registers this certificate with their Regional Medical Council (CRM) to obtain their official RQE (Registro de Qualificação de Especialista) under CFM regulations.
