CT and ultrasound (US) modalities are presented in the context of gastrointestinal carcinoma, carcinoid and round cell tumors, and the key features of these tumors are compared using clinical cases to best illustrate them in these 2 modalities.

 CT and US modalities are discussed in clinical scenarios of gastrointestinal Spindle cell tumors, and the key features of GI stromal tumors and smooth muscle tumors are covered and compared using clinical cases to best illustrate them.

 CT and US modalities are discussed in clinical scenarios of gastrointestinal Spindle cell tumors, and the key features of GI stromal tumors and smooth muscle tumors are covered and compared using clinical cases to best illustrate them.

 CT and US modalities are discussed in clinical cases of GI round cell tumors and carcinomas that are the most commonly represented GI tumors in cats.  Their imaging features are presented.

CT and US modalities are presented in lesions that mimic tumors in both dogs and cats.  Non-neoplastic lesions characterized by wall thickening with alteration or lost of layering include: granulomas, polyps/adenomas, hematoma/seroma, wall edema, and feline eosinophilic sclerosing fibroplasia.  Imaging features of these lesions will be discussed.

Recapitulative tables and statements covering the CT and US features of GI masses in dogs and cats are presented. Features and clinical information that lead to prioritizing a pertinent differential diagnosis, and guide the sampling procedure are discussed.

Prostate imaging: this lecture will provide an overview of imaging features in patients with prostatic neoplasia

TCC imaging: this lecture will provide an overview of imaging features in patients with bladder transitional cell carcinoma

Participants are expected to understand the anatomy of the adrenal glands and adjacent vessels and organs, to recognize, diagnose and know which type of tumors are more likely to invade adrenal glands, the difficulties and challenges of the adrenalectomy, the key information for the surgical planning and prognosis.

Participants are expected to understand and know the US and CT technique to image the adrenal glands and adrenal tumors, in particular to detect vascular invasion, to diagnose which type of tumors invade adrenal glands, which vessels are invaded, which tissues is adherent, the key information to provide in the US or CT report for the surgical planning and prognosis.

Sometimes, a retroperitoneal mass or lesion because of its location or because of its large size, may mimic an adrenal gland neoplasia. Sometimes, a retroperitoneal mass or lesion, which is not in the anatomic region of the adrenal gland, may originate from ectopic adrenal tissue or extra-adrenal ganglia. Participants are expected to know and understand the retroperitoneum anatomy and the reasoning in the diagnosis of extra-adrenal masses, originating or not from ectopic adrenal tissue or ganglia.

Pros and cons of CT and US in the evaluation of pancreatic neoplasia: The comparative benefits and limitations of CT and Ultrasound for the diagnosis of pancreatic neoplasia in dogs and cats will be reviewed.

Pancreatic carcinoma: US and CT key imaging features: Key imaging features of pancreatic carcinoma at ultrasound and CT will be reviewed and illustrated.
