Abstract
PET imaging with targeted radiotracers has become integral for mapping the location and burden of recurrent disease in patients with biochemical recurrence (BCR) of prostate cancer (PCa). PET with 11C-choline is part of the National Comprehensive Cancer Network and European Association of Urology guidelines for evaluation of BCR. With advances in PET technology, increasing use of targeted radiotracers, and improved survival of patients with BCR due to novel therapeutics, atypical sites of metastases are being increasingly encountered, challenging the conventional view that PCa rarely metastasizes beyond bones or lymph nodes. We describe such atypical metastases in the abdomen and pelvis on 11C-choline PET (including in the liver, pancreas, genital tract, urinary tract, peritoneum, and abdominal wall, as well as perineural spread), presenting multimodality imaging features and relevant imaging pitfalls. Given atypical metastases' inconsistent relationship with serum PSA and non-specific presenting symptoms, they are often first detected on imaging. Awareness of their imaging features is important as their detection impacts clinical management, patient counseling, prognosis, and clinical trial eligibility. Such awareness is particularly critical as the role of radiologists in the imaging and management of BCR will continue to increase given the expanding regulatory approvals of other targeted and theranostic radiotracers.

Abstract
ABSTRACT An 81-year-old man received androgen deprivation therapy for a locally advanced prostate cancer and, 6 months later, a curative radiation therapy. Half a year later, the patient presented with a steeply increased PSA value (32 ng/mL) and a suppressed testosterone level (0.48 nmol/L). The consecutively performed 68Ga-PSMA PET/CT revealed, besides local tumor remains and several PSMA-positive lymph node and soft tissue metastases, an extensive, diffuse PSMA ligand accumulation in the omentum, which was immunohistochemically proven to be a carcinomatosis of prostate cancer. None of the extraprostatic lesions were present in the pretherapeutic PSMA PET 1 year ago.

Prostate Cancer Nonascitic Peritoneal Carcinomatosis After Robot-assisted Laparoscopic Radical Prostatectomy: 3 Case Reports and Review of the Literature. Urology 2019; 137:121-125.

Abstract
Robot-assisted laparoscopic radical prostatectomy is one of the treatment options for localized prostate cancer, with an excellent disease control rate. However, these patients can experience late disease recurrence with metastatic dissemination. Peritoneal metastases are an uncommon recurrence site. Here, we discuss 3 cases of peritoneal metastases following robot-assisted laparoscopic radical prostatectomy and the mechanisms of peritoneal invasion. Through a literature review and our case reports, we postulate the existence of 2 distinct mechanisms of peritoneal invasion: one being iatrogenic, following a laparoscopic surgery with a well differentiated prostate cancer at a nonadvanced stage of the disease, the other involving the natural course of poor-prognosis tumors, even without surgery.

Abstract
Malignant ascites in prostatic acinar adenocarcinoma is very rare. We present an 84-year-old man with a rare malignant ascites due to prostatic adenocarcinoma demonstrating hepatoid differentiation by immunohistochemistry. The patient was diagnosed with the malignant ascites due to metastatic prostatic adenocarcinoma. We identified the unique cytological feature of envelopment of tumour cell clusters by benign mesothelial monolayers.

Abstract
In patients with prostate cancer, metastases mostly develop in bone, lung, liver, pleura and adrenal glands. Prostate carcinoma metastases to the ureter are very rare, and the peritoneum is an even rarer site of prostate metastases. We present two cases of ureteral metastases of prostate cancer, of which one patient also developed malignant ascites and peritoneal metastases. An overview of the literature on these metastatic sites is also provided. Both patients presented with hydronephrosis and a ureteral mass. Biopsies of the masses were taken, which showed the presence of prostate carcinoma metastases. The first patient was treated with chemotherapy but was diagnosed with progressive disease and died 3 years later. The second patient was diagnosed with pathology-confirmed peritoneal metastases 8 months later. He died 2 years after presentation with hydronephrosis.

Abstract
We present a case of 55-year-old man who complained of dyspnea and sputum for a month. He was an ex-smoker with a history of prostate cancer and pulmonary tuberculosis. Chest radiographs revealed bilateral pleural effusions of a small to moderate amount. Pigtail catheters were inserted for drainage. The pleural fluid consisted of large clusters and tightly cohesive groups of malignant cells, which however could not be ascribed to prostate cancer with certainty. We performed immunocytochemical panel studies to determine the origin of cancer metastasis. The immunostaining results were positive for prostate-specific antigen, alpha-methylacyl-coenzyme A racemase, and Nkx 3.1, consistent with prostate cancer. Pleural effusion associated with prostate cancer is rare. To our knowledge, this is the first case report in Korea to describe cytologic features of malignant pleural effusion associated with prostate cancer.

Abstract
Prostate cancer is one of the leading causes of cancer death in men. The prognosis in prostate cancer is greatly worsened by the presence of metastases, which are most commonly found in bone, lung, liver, and brain. The peritoneum is an extremely uncommon metastatic site for prostate cancer, even in autopsy series. We present a case of FDG PET/CT demonstration of peritoneal metastasis from prostate cancer.
