Brunner gland hyperplasia, a rare duodenal tumor, usually presents with benign features. A 68-year-old man with a history of anemia presented with a polypoid duodenal mass that was detected by CT and esophagogastroduodenoscopy. This mass showed high F-FDG avidity on PET/CT and was histopathologically confirmed as Brunner gland hyperplasia. We suggest that Brunner gland hyperplasia should be considered in the differential diagnosis of F-FDG-avid duodenal tumors.

We report about the usefulness of F-FDG PET for the detection and therapy response evaluation of renal sarcoidosis. A 55-year-old woman presented with a condition diagnosed with pulmonary and ocular sarcoidosis 2 years before having anemia and acute deterioration of renal function. FDG PET revealed diffuse increased FDG uptake in both kidneys and the spleen. Histopathologic examination of a renal biopsy sample revealed granulomatous interstitial nephritis with sarcoidosis. After methylprednisolone treatment, the abnormal FDG uptake resolved completely with improvement of symptoms. FDG PET is a useful tool to detect active sarcoidosis regions and to monitor treatment efficacy.

Multiple myeloma (MM) is a relatively rare hematologic disorder characterized by proliferation of plasma cells, primarily involving the bone marrow. Extramedullary involvement also occurs with poor prognosis. Asymptomatic plasma cell disorders, monoclonal gammopathy of uncertain significance, and smoldering MM, which do not require therapy, should be distinguished from symptomatic MM, which requires treatment. MM may present with CRAB, elevated Calcium levels, Renal insufficiency, Anemia, and Bone lesions (including lytic lesions and osteopenia), as well as elevated levels of serum M protein or urine M protein or both. Nonsecretory myeloma in which serum and urine M proteins are absent occurs rarely, accounting for 1%-5% of patients with myeloma, but low levels of abnormal immunoglobulins are often present. Staging of patients with MM is done according to the Durie and Salmon criteria based on laboratory testing (determination of hemoglobin, serum calcium, and serum and urine M proteins) and conventional radiography. A variety of diagnostic imaging procedures have been employed to assess the extent of disease in MM and to evaluate the response to treatment as well as provide surveillance for the detection of recurrent disease. These include whole-body x-ray, which despite its limitations is regularly used to detect lytic bone lesions; CT radiography; MRI; and a variety of radionuclide imaging procedures, with (18)F-FDG-PET/CT emerging as the radionuclide procedure of choice. Recently, the Durie-Salmon criteria have been upgrade to the Durie-Salmon PLUS system, which includes (18)F-FDG-PET/CT and MRI of the spine and pelvis.

A 75-year-old man who had undergone subtotal gastrectomy for advanced gastric cancer 18 years previously with no signs of recurrence visited our hospital because of anemia detected by medical examination. Although no clinical abnormalities were evident, treatment with iron and vitamin B12 was started. However, because serum ALP was elevated, metastatic bone cancer was suspected. Subsequently, upper gastrointestinal endoscopy revealed findings suggestive of residual gastric cancer, and examination of a biopsy specimen demonstrated signet ring cell carcinoma. Furthermore, cells in a bone marrow biopsy sample showed morphology similar to that of cells obtained by stomach biopsy. FDG-PET demonstrated FDG accumulation only in the bone and residual stomach. The final diagnosis was bone metastasis from residual gastric cancer, and disseminated carcinomatosis of the bone marrow. Thereafter, pancytopenia progressed rapidly, and the patient died due to disseminated intravascular coagulation. When serum ALP is elevated in patients with a history of gastric cancer, bone marrow carcinomatosis should be suspected irrespective of symptoms, and imaging studies and bone marrow examination should be performed.

We report the case of a 64-year-old white male who presented to his primary care physician with complaints of fatigue. Physical exam was unremarkable and laboratory studies revealed profound anemia, for which the patient received a transfusion. Esophagogastroduodenoscopy revealed a bleeding mass in the proximal stomach that was histologically determined to be malignant melanoma, with immunohistochemical staining demonstrating positivity for SOX10, S100, MART-1, and HMG-45. After an extensive dermatological exam no other primary lesion was identified. Whole body positron emission tomography (18-FDG-PET/CT) demonstrated pathologic uptake only in the area of the proximal stomach. For this reason, primary gastric melanoma was suspected in this patient. The patient underwent subtotal gastrectomy with mass excision followed by Roux-en-Y reconstruction. Very few cases of primary gastric melanoma have been reported. We report this case and present diagnostic criteria for primary non-cutaneous melanoma and discuss potential non-surgical therapies.

A 53-year-old man with metastatic melanoma, in remission, presented with an 8-week history of melena and anemia. Initial investigations including upper and lower gastrointestinal endoscopy, capsule endoscopy, and Tc-labeled red blood cell scan did not reveal a source of bleeding. Given the concern over melanoma recurrence, F-FDG PET/CT was performed that demonstrated a focus of intense uptake in the small bowel. Uncomplicated surgical resection of the segment of jejunum containing the lesion was performed, after which the patient reported no further gastrointestinal bleeding. Histopathological assessment of the lesion was consistent with pyogenic granuloma.

We describe herein the case of an adolescent girl with anemia non-responsive to oral iron, associated with low-grade fever, diminished appetite and fatigue. A palpable mass below the xiphoid was noted. Laboratory findings were consistent with anemia of inflammation. Direct antiglobulin test was positive without any other evidence of autoimmune anemia. Other autoantibodies, such as anti-thyroid and anti-nuclear antibodies, were also positive. After thorough investigation, Castleman disease was the most likely diagnosis on the basis of high serum interleukin (IL)-6 and the magnetic resonance imaging findings. (18)F-FDG positron emission tomography-computed tomography showed a localized hypermetabolic mass, which was resected. Castleman disease of plasma type was identified on histology. Hemogloblin and IL-6 gradually returned to normal, whereas positive autoantibodies became negative. This case emphasizes the need to investigate thoroughly for the underlying cause of anemia of inflammation and to include Castleman disease in the differential diagnosis, on the measurement of IL-6.

Kaposiform hemangioendothelioma (KH) is a rare vascular tumor of intermediate malignancy that occurs mainly in the childhood. Adult patients with KH are rare. Imaging findings of KH have rarely been reported before. We present magnetic resonance imaging (MRI), computed tomography (CT), and fluorine-18-fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/CT findings in an adult patient with KH associated with lymphangiomatosis involving mesentery and ileum.A 22-year-old female complained of a 9-month history of intermittent melena, weakness, and palpitation. Laboratory tests revealed anemia and hypoproteinemia. Fecal occult blood test was positive. Abdominal enhanced MRI and CT showed a large abdominal mass involving mesentery and ileum. On enhanced MRI, there were many hypervascular nodules in the mass. On FDG PET/CT, the mass and the nodules showed slight FDG uptake. Small bowel capsule endoscopy showed numerous grape-shaped red nodules in the luminal wall of the involved ileum. The patient underwent resection of the abdominal mass and a segment of the ileum invaded by the abdominal mass. KH arising within lymphangiomatosis involving mesentery and ileum was confirmed by pathology. After surgery, the patient's symptoms improved.This is the first case of KH associated with lymphangiomatosis involving mesentery and ileum. In this case, the lymphangiomatosis overshadowed the small tumor nodules resulting in unusual imaging findings. Familiarity with these imaging findings is helpful for diagnosis and differential diagnosis of KH.

The aim of this study was to evaluate the response and hematological toxicity in peptide receptor radionuclide therapy (PRRT) with lutetium ((177)Lu)-DOTA-octreotate (DOTATATE) in metastatic neuroendocrine tumor (NET) with extensive bone marrow metastasis at the initial diagnosis. A retrospective evaluation was undertaken for this purpose: Patients with NET with extensive diffuse bone marrow involvement at diagnosis who had received at least three cycles of PRRT with (177)Lu-DOTATATE were considered for the analysis. The selected patients were analyzed for the following: (i) Patient and lesional characteristics, (ii) associated metastatic burden, (iii) hematological parameters at diagnosis and during the course of therapy, (iv) response to PRRT (using a 3-parameter assessment: Symptomatic including Karnofsky/Lansky performance score, biochemical finding, and scan finding), (v) dual tracer imaging features [with somatostatin receptor imaging (SRI) and fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT)]. Based on the visual grading, tracer uptake in somatostatin receptor (SSTR)-positive bone marrow lesions were graded by a 4-point scale into four categories (0-III) in comparison with the hepatic uptake on the scan: 0 - no uptake; I - clear focus but less than liver uptake; II - equal to liver uptake; and III - higher than liver uptake]. Hematological toxicity was evaluated using National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 score. A total of five patients (age range: 26-62 years; three males and two females) with diffuse bone marrow involvement at the diagnosis was encountered following analysis of the entire patient population of 250 patients. Based on the site of the primary, three had thoracic NET (two patients bronchial carcinoid and one pulmonary NET) and two gastroenteropancreatic NET (one in the duodenum and one patient of unknown primary with liver metastasis). Associated sites of metastases included the liver (n = 5), breast (n = 1), and aortocaval nodes (n = 1). On baseline diagnostic study [(68) Ga-DOTANOC/TATE or the technetium ((99m)Tc)-hydrazinonicotinamide (HYNIC)-tektrotyd (TOC)], tracer uptake in the bone marrow in all patients was Grade III. At the time of analysis, the patients received three to four cycles of PRRT and a cumulative dose of 16.1-25.6 GBq with a follow-up duration ranging 10-27 months. The response as assessed by three parameters: (i) Symptomatic: All patients (except for one) reported excellent symptomatic palliation and better quality of life with improvement of Karnofsky/Lansky scores; the single case with nonresponse had shown symptomatic response in the initial 6 months following which he had a progressive disease and death at 18 months (ii) biochemical: Three patients had shown more than 50% reduction in the serum chromogranin level, one had shown increase but had demonstrated clinical evidence of response with radiologically stable disease while the other who had shown slight increase of chromogranin A (CgA) level had shown progressive disease thereafter (iii) radiological: Three patients demonstrated partial response (on FDG-PET/CT), one patient had stable disease and one patient had progressive disease following initial clinical response. As per the NCI-CTCAE score, only one patient had persistent Grade I anemia without any deterioration with the administered dose at the time of analysis. FDG uptake in the bone marrow metastatic lesions showed no obvious FDG avidity on visual assessment except for two patients (low-grade FDG uptake). Interestingly, the associated metastatic lesions [except for patient I with Mib1 labeling index (LI): 1-2%], demonstrated high FDG avidity. Thus, we observed that the majority (in our series four out of five patients, i.e. 80%) of the patients had excellent symptomatic response with at least stabilization of the disease at a follow-up period of 10-27 months. The single patient who had a progressive disease also had a good symptomatic response in the initial 6 months from the first dose of PRRT. Despite the extensive bone marrow involvement, no hematological toxicity was observed (only one patient showed Grade I anemia), suggesting that PRRT is well-tolerated by this particular subgroup.

A 72-year-old woman presented with symptomatic anemia without abdominal symptoms. She had no history of abdominal surgery or use of non-steroidal anti-inflammatory drugs. Enhanced computed tomography of the abdomen revealed swelling of multiple intraperitoneal lymph nodes and a high density of mesenteric adipose tissue. Fluorodeoxyglucose (FDG-) positron emission tomography showed high FDG accumulation at the intraperitoneal lymph nodes. Double-balloon enteroscopy detected severe stenosis with an annular ulcer in the lower ileum. She was diagnosed with ileal follicular lymphoma based on histologic examination and fluorescence in situ hybridization analysis of the biopsy specimen. The ileal ulcer was successfully treated by chemotherapy with rituximab and bendamustine for 1 year. We strongly recommend consideration of gastrointestinal follicular lymphoma in the differential diagnosis of annular ulcers in the small intestine.
