Summary: This article discusses the classification, pathological diagnosis, and radiological features of primary tumors of the pituitary gland. Pituitary adenomas, whether functional or silent, are the most common type, while pituitary carcinoma and pituitary blastoma are rarer and characterized by metastatic disease and infantile presentation, respectively. The article also touches on the challenges of accurate detection and the local mass effect posed by microadenomas and macroadenomas, respectively.

Summary: Urinary bladder masses are commonly encountered in clinical practice, and their classification is challenging due to the diverse array of pathologic entities that can arise from the bladder. Pathologic assessment remains the standard of care for distinguishing between benign, malignant, and nonneoplastic entities.

Summary: After mastectomy, patients are not universally screened with mammography or US, highlighting the importance of clinical breast examination and patient-detected abnormalities. Understanding the imaging appearances and locations of palpable abnormalities is crucial for diagnosis and treatment.

Summary: Fibroblastic and myofibroblastic tumors are a group of neoplasms that range from benign to malignant and are more commonly found in pediatric patients. The 2020 WHO classification categorizes these tumors based on their biological behavior, histomorphologic characteristics, and molecular profiles. Imaging can aid in predicting histopathologic variations, influencing diagnosis, prognosis, and treatment planning. Understanding the radiologic-pathologic correlation can improve the accuracy of percutaneous biopsy and prevent unnecessary interventions.

Summary: The study found that testicular ultrasound significantly underestimated the pathologic size of masses less than 2 cm, while tumor volume measurements may be more accurate in predicting benign pathology compared to maximum diameter measurements. Further research is needed to confirm these findings.

Summary: Tracheobronchial neoplasms are less common than lung parenchymal neoplasms, but they can cause significant morbidity and mortality. They include a wide range of malignant and benign entities, beyond commonly known conditions such as squamous cell carcinoma and carcinoid tumor. Knowledge of potential distinguishing factors can help narrow the differential diagnosis.

Summary: Mesenchymal tumors of the stomach, with GIST being the most common type, can originate from various types of cells. Imaging plays a crucial role in determining the characteristics and locations of these tumors, although a biopsy is often required for a definitive diagnosis.

Summary: Recent advancements in nerve-sparing robotic prostatectomy have reduced side effects such as urinary incontinence and sexual dysfunction. However, Magnetic Resonance Imaging (MRI), although being the gold-standard imaging method for Prostate Cancer (PCa) staging, lacks specificity in detecting extracapsular extension (ECE). Therefore, understanding the histopathological aspects of ECE is crucial for evaluating MRI findings of PCa. Our review focuses on correlating the normal MRI appearance of the prostate gland and the periprostatic space with prostatectomy specimens, exemplifying the different findings of ECE and neurovascular bundle invasion with both MRI and histologic images.

Summary: Renal cell carcinoma (RCC) is a group of neoplasms derived from renal tubular epithelial cells. Chromophobe RCC (chRCC) is the third most common subtype of RCC, accounting for 5% of cases. Surgical resection is the main therapy for chRCC, which has a better prognosis compared to clear cell RCC. Pathologic analysis shows chRCC as a solid well-defined mass with histologic features such as abundant transparent cytoplasm and crinkled nuclei.

Summary: Orbital masses can be benign or malignant, and are often asymptomatic or grow slowly, leading to delayed clinical symptoms. Cross-sectional imaging is essential for characterizing these masses and assessing the involved compartments, enabling optimal treatment and surgery planning. This review explores the typical appearance of different benign and malignant orbital tumors in imaging and their histopathologic findings.

Summary: Primary cardiac and pericardial neoplasms are rare in children, including benign and malignant lesions. The most common benign tumors are rhabdomyomas, teratomas, fibromas, and hemangiomas. Soft-tissue sarcomas are the most common primary cardiac malignancies. Noninvasive cardiac imaging is helpful for diagnosis.
