CT allows adequate evaluation of neuroendocrine small bowel tumor and extra-enteric abnormalities.

Consider atypical PRES and a vascular work-up in brainstem edema, especially in the setting of severe hypertension.

Transient interlobular septal nodules displaying a characteristic branched 'pearl-like' pattern may reflect acute pulmonary lymphatic overload and should not be mistaken for other common pathological processes.

Endophthalmitis is an uncommon but severe complication of meningitis that can be visualized on MRI.

Pulmonary and systemic arterial phases are needed to exclude Rasmussen aneurysm.

Melorheostosis may exceptionally present with extraosseous extension mimicking a cartilaginous tumor, emphasizing the crucial role of anatomo-radiological correlation when histology is confusing.

Air space opacities, either consolidation or ground glass, are the most frequent imaging finding in EGPA patients with pulmonary involvement, often bilateral and mostly peripheral or random in distribution.

Osteofibrous dysplasia (OFD) is a rare benign fibro‑osseous lesion primarily affecting the tibial cortex in children and adolescents; simultaneous involvement of the fibula is exceptional and may mimic more aggressive tumors such as adamantinoma.

Retroperitoneal lipomatosis is a benign idiopathic process resulting in a progressive, symmetrical and homogeneous increased retroperitoneal fat lesion without areas of increased density.

An angioleiomyoma is a benign superficial tumor that presents with relatively characteristic features on US and MRI.

Exuberant honeycombing on high-resolution computed tomography of the chest is a specific sign of connective tissue disease-associated interstitial lung disease with a usual interstitial pneumonia pattern and contributes to differentiate it from idiopathic pulmonary fibrosis.

Even when the nasogastric tube (NGT) tip appears intragastric on chest radiography, malposition of proximal side holes above the gastro-oesophageal junction may result in clinically significant aspiration.

Pulmonary artery intimal sarcoma is a very rare and often misdiagnosed cause of pulmonary artery occlusion and progressive dyspnoea. A case of a 66-year-old man is presented, initially treated for presumed pulmonary embolism, in whom persistent intraluminal filling defects and inadequate therapeutic response ultimately led to the diagnosis of intimal sarcoma. Pulmonary artery intimal sarcoma should be considered in cases of persistent suspected pulmonary embolism unresponsive to adequate anticoagulation or thrombolysis, with imaging features such as SUVmax, metabolic tumour volume, total lesion glycolysis, and the wall eclipsing sign helping in the differentiation between the two entities.

A rare case of hepatic gas-forming metastases secondary to infection is described. A 78-year-old woman was admitted with right lower quadrant abdominal pain and deterioration. Initial imaging revealed a right-sided colonic malignancy with hepatic metastases. Follow-up scans showed gas within metastases and minimal pneumoperitoneum, suggesting bowel perforation. However, blood cultures isolated , supporting infected necrotic metastases as the source of free gas. This case emphasizes the importance of distinguishing infectious intratumoral gas from perforation in oncological patients and provides one of the few reports with sequential imaging of this process.

An exceptionally rare case is described of intraparenchymal WHO grade 2 meningioma with suspected meningioangiomatosis in a nine‑month‑old boy presenting with absence seizures. MRI revealed a heterogeneously enhancing right frontal mass without dural attachment, encasing MCA branches. Histopathology confirmed atypical meningioma with adjacent perivascular meningothelial proliferation. Methylation profiling supported the diagnosis. Following gross total resection without adjuvant therapy, the patient remains seizure‑free with no recurrence at four‑year follow‑up. Pediatric meningiomas are rare tumors that exhibit atypical presentations compared to their adult counterparts and should be included in the differential diagnosis of intra‑axial lesions in children.

Laceration of the left hepatic vein is a rare but potentially fatal complication of cardiopulmonary resuscitation (CPR) and should be considered in patients with unexplained hemodynamic instability following resuscitation.

When a polyostotic lesion in the fingers is seen in a pediatric patient, fibrous dysplasia should be included in the differential diagnosis and a CT scan should be considered for the assessment of ground-glass densities.

A 68-year-old woman presented with progressive hemiparesis and dysphagia, initially presumed to have subacute stroke. Serial MRI revealed fluctuating FLAIR hyperintensities and enhancing lesions in the basal ganglia and cortex, ultimately leading to the diagnosis of high-grade primary CNS B-cell lymphoma. The case highlights the importance of integrating clinical evolution with imaging features in atypical neurological presentations. In cases of fluctuating FLAIR hyperintensity and contrast-enhancing brain lesions, primary CNS lymphoma should be considered, even in the absence of typical imaging features.

We report the case of a 45-year-old man with a rare cerebellar dural arteriovenous fistula (dAVF) presenting with dizziness and gait imbalance. MRI revealed a hemorrhagic lesion compressing the fourth ventricle. Digital subtraction angiography confirmed a Borden Type III dAVF, which was successfully treated by balloon-assisted embolization using PHIL 25%. This case draws attention to the importance of early diagnosis and intervention in posterior fossa dAVFs. Cerebellar dAVFs, though rare, harbor a high risk of hemorrhage and require prompt imaging and endovascular treatment.

Gallbladder volvulus is a rare but serious diagnosis that needs urgent surgical treatment to avoid morbidity and mortality related to gallbladder ischemia and should be suspected in elderly female patients with acute right upper quadrant pain with imaging features including enlarged, abnormally positioned gallbladder and specific key findings on CT including "whirl sign" representing twisting of the cystic pedicle and "beak sign" at the gallbladder neck.

T2 Dixon imaging is valuable in assessing soft tissue lesions. Water-only images highlight fluid or edema, while fat-only images identify macroscopic fat and help delineate fat-devoid regions, which often indicate suspicious areas-or confirm their absence in benign lesions.
