The contribution of ¹⁸F-FDG PET/CT in a patient with cutaneous metastases of squamous cell carcinoma of the penis.

A 61-year-old patient was diagnosed with squamous cell carcinoma of the penis (SCCP) and treated with partial penectomy (pT1,N0,M0,G2). Seven months later, a palpable adenopathy was found in the left inguinal region. An (18)F-FDG PET/CT exploration showed hypermetabolic lymphadenopathies in inguinal, pelvic, retroperitoneal regions, in both lung hila and in the left supraclavicular regions.

Radioguided surgery in Meckel's diverticulum.

We analyze the case of a patient with intermittent episodes of lower gastrointestinal bleeding and suspected Meckel's diverticulum, whose presence was confirmed by (99m)Tc-pertechnetate scintigraphy. A previous exploratory laparotomy had been performed without finding the diverticulum. In spite of years of medical treatment, the patient presented a new episode of lower gastrointestinal bleeding with normal colonoscopy.

[18F-FDG PET/CT diagnosis of liver cyst infection in a patient with autosomal dominant polycystic kidney disease and fever of unknown origin].

The diagnosis, localization and treatment of infected cysts in the kidney or liver of patients with autosomal dominant polycystic kidney disease (ADPKD) remain a clinical challenge. We report the findings of (18)F-FDG PET-CT in an ADPKD diagnosed patient who required renal transplantation five years before and in his follow up presented repeated episodes of bacteriemia without known focus on radiological tests performed. The (18)F-FDG PET-CT scan showed numerous hypermetabolic images with focal or ring-shaped morphology related to the content and the wall of some hepatic cysts.
