ABSTRACT
ABSTRACT: We describe a 57-year-old man with prostate cancer. A radical prostatectomy with a pelvic lymphadenectomy was performed. After 2 years, a mild swelling of the lower extremities appeared, and the patient was referred for lower-limb lymphoscintigraphy. A lymphoscintigraphy of the superficial lymphatic system in the limbs showed prominent, dermal backflow in the area of the right hypogastrium. Lymphoscintigraphy of the deep lymphatic system showed reflux in the left hypogastrium. This discrepancy between the findings in the superficial and deep lower-limb lymphatic systems was explained by asymmetric sampling of the lymph nodes during the lymphadenectomy.

In June 2018, 77-year-old man was referred to The Department of Haematooncology, University Hospital Ostrava, for suspicion of multiple myeloma. This was supported by laboratory findings of hypercalcemia, paraprotein IgA κ in serum and by the presence of multiple osteolytic skeletal lesions. Low number of plasma cells in bone marrow sample - cytologically (3.6 %) as well as in flow cytometry (less than 95 % clonal plasma cells out of total bone marrow plasma cells) - pointed at the direction of monoclonal gammopathy of undetermined significance (MGUS). In the course of differential diagnosis of hypercalcemia, elevated level of parathormone had been found which led to the performance of 99mTc-MIBI scintigraphy where parathyroid adenoma was discovered and later histologically verified. The final diagnosis was determined as a coincidence of MGUS and primary hyperparathyroidism. This case report also contains brief differential diagnosis of hypercalcemia and osteolytic skeletal lesions and suggestions for their diagnostic algorithms.

We present the case of a 26-year-old man with congenital primary lymphedema. A lymphedema of the right upper limb appeared at the age of 2 years, followed by edemas of the right lower limb and of the right part of the head and neck. A lymphedema of the left lower limb began 5 years ago, and finally an edema of the external genitalia began 2 years ago. Lymphoscintigraphy of the lower limbs and pelvic/abdominal region (including SPECT/ldCT) revealed interesting abnormalities.
