Prognostic value of haematological parameters and [F]FDG PET/CT metabolic parameters in head and neck cancer.

Aim: To determine the usefulness of neutrophil/lymphocyte (N/L) and platelet/lymphocyte (P/L) ratios as well as quantitative [F]FDG PET/CT parameters as prognostic factors for overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS) in patients with head and neck squamous cell carcinoma (HyN).

Material And Methods: Sixty-six patients (56 men) diagnosed with HyN carcinoma were retrospectively assessed over an 8-year interval. Maximum SUV (SUV), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) parameters were determined from the PET/CT study at diagnosis.

Lumbar Gout Tophus Mimicking Epidural Abscess with Magnetic Resonance Imaging, Bone, and Gallium Scans.

Gout is a common metabolic disorder, typically diagnosed in peripheral joints. Tophaceous deposits in lumbar spine are a very rare condition with very few cases reported in literature. The following is a case report of a 52-year-old patient with low back pain, left leg pain, and numbness.

Mismatch in Brain Perfusion and Metabolism Detected with Tc-Hexamethyl Propylene Amine Oxime Single Photon Emission Computed Tomography and F-Fluorodeoxyglucose Positron Emission Tomography in Moyamoya Disease.

We report a 47-year-old woman who developed an ischemic stroke with diplopia and dysarthria. Emergency computed tomography (CT) showed no pathological findings, and magnetic resonance (MR) showed mild ischemic-degenerative lesions. MR angiography and angiogram showed severe stenosis of both internal carotid and main intracranial arteries with plenty collateral vessels with "puff of smoke" suggesting a moyamoya disease (MMD).

Bilateral alien hand syndrome in cerebrovascular disease: CT, MR, CT angiography, and 99mTc-HMPAO-SPECT findings.

We report a 65-year-old man with a right cerebral infarction that occurred 15 years ago and a residual left hemiparesis that began with progressive contralateral hemiparesis. During the hospitalization, the patient developed a bilateral alien hand syndrome. Urgent CT, MR, CT angiography, and brain perfusion SPECT were performed that revealed an old right cerebral infarction and a new ischemic lesion in left parietal lobe and adjacent brain territories.

"Shin splint" syndrome and tibial stress fracture in the same patient diagnosed by means of (99m)Tc-HMDP SPECT/CT.

We show a patient who presented leg pain triggered by intense exercise. The most likely diagnosis was a possible tibial stress fracture or a "shin splint" syndrome (soleus enthesopathy). We performed a bone scintigraphy including SPECT/CT that revealed the presence of the two concomitant pathologies.

Bilateral axillary and internal mammary drainage in breast cancer without prior surgery during sentinel node mapping.

Lymphatic drainage outside the ipsilateral axilla in breast cancer is discovered in as many as 25% of all sentinel lymph node procedures and it is evidenced by lymphoscintigraphy. Contralateral axillary drainage is a rare clinical situation, mostly if there is not prior breast surgery, but this situation is extremely exceptional if we also found internal mammary chain drainage. We have not found such a case published in literature.

Adrenal metastasis of breast cancer with involvement of the inferior vena cava.

Tumour thrombosis of the inferior cava vein is usually associated with primary renal cell cancer. To our knowledge, this is the first case reported of adrenal metastasis of breast cancer extending into the inferior vena cava. There are few references in the literature documenting this extension with positron emission tomography (PET) and enhanced computed tomography (CT).
