A 68-year-old right-handed woman was admitted to Tokyo Metropolitan Geriatric Hospital because of slowly progressive dysarthria and writing disability over 2-year period. On admission, severe dysarthria was observed, but no dysphagia. The dysarthria mostly resembled a type of pseudobulbar palsy, although it was associated with effortful speech production. An oro-facial apraxia was also found. She could name objects, and could understand spoken words correctly. Examination using the Western Aphasia Battery showed diminution of word fluency, impaired repetition and perseveration and writing errors. On the Wechsler Adult Intelligence Scale-R verbal IQ was 100 and performance IQ was 87. These scores did not suggest any significant degree of general intellectual deterioration. Wisconsin card sorting test disclosed mild frontal dysfunction. Magnetic resonance imaging showed cortical atrophy in the bilateral frontal and temporal lobes. Measurements of regional cerebral metabolic rate by 18F-FDG-PET demonstrated decreased uptake in the latero-dorso-inferior area of the bilateral frontal lobes, especially on the left side. The present case showed slowly progressive dysarthria and progressive aphasia without generalized dementia, and without typical aphasia. These symptoms are speculated to be related to the atrophy in the bilateral frontal and temporal lobes shown by MRI and the decreased metabolic rate in the left dominant bilateral frontal lobes on PET study. The pathologic process responsible for these lesions remains obscure.

We reported a 67-year-old male, who suffered from apraxia and amnesia for 2 years and for muscle rigidity of right extremities for a year. Neurological examination revealed dysarthria, dysphagia, marked dystonia of right arm, hyperreflexia of all limbs and ataxic gait. He also had dementia and many other higher cortical dysfunction mostly due to left hemisphere damage. No impairment of eye movement was disclosed. Brain MRI as well as CT showed the significant brain atrophy in the left parieto-occipital region. A degenerative atrophy was suspected by 123I-IMP-SPECT and 18F-FDG-PET. By FDG-PET, the decrease of cerebral blood flow and glucose metabolism was detected not only affected unilateral cerebral cortex including primary motor area but ipsilateral basal ganglia and thalamus. Although, it is difficult to distinguish clinically CBD from atypical case of Alzheimer's disease, we speculated that in early stage of dementia, significant unilateral hypoperfusion and hypometabolism of basal ganglia and thalamus is characteristic of CBD.

Pallido-luysio-nigral atrophy (PLNA) is a rare neurodegenerative disease in which the clinical and radiologic correlates have not yet been clearly established. A 62-year-old man insidiously developed dystonic postures, choreoathetoid movements, slowness, and stiffness, which initially affected the right hand and foot and progressively spread to the entire right side. T2-weighted magnetic resonance imaging showed increased signal intensity in both left and right medial pallida and in the left substantia nigra. Tests using HMPAO-SPECT and FDG-PET demonstrated left cortical hyperperfusion and hypermetabolism, whereas the left lenticular nucleus was slightly hypometabolic. At age 65, abnormal movements and postures involved all four limbs and the axis causing major gait disturbances, and facial and bulbar muscles atrophied resulting in dysarthria, dysphagia, and impaired breathing. Diffuse amyotrophy and fasciculations also appeared. Death occurred at age 66, 4 years after onset. At autopsy, severe bilateral neuronal loss and gliosis restricted to the pallidum, the subthalamic nucleus, the substantia nigra, and the hypoglossal nucleus were noted, accounting for the diagnosis of PLNA with lower motor neuron involvement. Progressive hemidystonia with adult onset represents an unusual clinical presentation for this disorder. Moreover, this observation indicates that a diagnosis of PLNA should be considered for specific magnetic resonance imaging, SPECT, and/or PET data, and suggests that in PLNA, pallidal dysfunction might play a key role in the dystonic presentation.

A 35-year-old female ingested a lethal dose of potassium cyanide in a suicide attempt. She survived following antidote therapy and intensive care. Following artificial coma she presented with an agitative state for several days followed by akinetic mutism, buccofacial and ideomotoric aphasia. Severe rigid-akinetic syndrome, dysarthria, dysphagia and generalized dystonia developed weeks later. MRI revealed lesions in the caudate and lentiform nuclei, precentral cortex, and cerebellum. SPECT by [123-I] 2 beta-carbomethoxy-3-beta-(4-iodophenyl)-Tropan on two occasions revealed progressive loss of dopamine transporter suggestive of nigral neuronal apoptosis. Striatal and frontal hypometabolism and hypoperfusion were found by FDG-PET and HMPAO SPECT.

A 67-year-old man with progressive dysphagia was recently diagnosed with a gastroesophageal junction adenocarcinoma. Contrast-enhanced CT scans of the abdomen and pelvis reported a large GE junction tumor without evidence of metastatic disease. FDG positron emission tomography revealed intense tracer accumulation in the soft tissue mass at the GE junction consistent with the primary neoplasm. In addition, PET scan also identified a solitary focus of intense FDG accumulation at the musculotendinous junction of the right gluteus minimus muscle. Subsequent MRI demonstrated mild enhancement and could not differentiate between tumor versus inflammation. Needle biopsy was performed and confirmed metastatic esophageal adenocarcinoma. A case of skeletal muscle metastases from late-stage (IV) gastroesophageal adenocarcinoma was previously reported. However, a solitary metastasis to a distant skeletal muscle without evidence of other lymphatic and hematogenous metastasis is quite unusual. The case supports the previous report that PET is superior in detecting distant metastases for initial staging of esophageal carcinoma over CT.

Dysphagia, dysphonia, dyspnoea, cervical lymph nodes are commonly indicative of head and neck carcinoma, although non specific signs, like otologic or rhinologic symptoms may be present. In addition to physical examination done on the patient awake and panendoscopy under anesthesia with biopsies, the diagnostic evaluation includes different imaging modalities (computed tomography, and/or magnetic resonance imaging, and positron emission tomography with FDG). Preoperative assessment of tumour extent, cervical lymph node involvement as well as distant metastases is mandatory for both staging and planning the best accurate therapy in these patients.

We observed a 42-year-old woman presenting with severe dysphagia secondary to paralysis of the lower cranial nerves and right phrenic nerve involvement, followed by respiratory failure. An EMG confirmed bilateral denervation of the 9th, 10th, 11th and 12th cranial nerves and right phrenic nerve. Videolaryngoscopy showed bilateral vocal fold immobility. Anemia, elevated ESR, microhematuria and C-ANCA (PR-3) antibodies were detected. Brain MRI and CSF were normal. A chest CT showed bilateral, irregular pulmonary lesions. An 18F-FDG total body scan showed diffuse hypermetabolic regions in both pulmonary bases, in the mediastinic region and in the rhinopharynx, raising the suspicion of a neoplastic process. A transthoracic biopsy disclosed nodular granulomatous aggregates with multinucleated giant cells, supporting the diagnosis of Wegener's granulomatosis. Immunosuppressive therapy achieved complete clinical resolution and cleared the pulmonary lesions. To the best of our knowledge this is the first report of Wegener's granulomatosis presenting with neurogenic dysphagia due to lower cranial nerve palsy.

We present an F-18 FDG PET scan which demonstrates 3 synchronous primary malignancies. The patient is a 61-year-old man who presented with weight loss and dysphagia. He was initially diagnosed with squamous cell carcinoma of the midesophagus, and was then found to have an adenocarcinoma in the right lung. A staging PET scan additionally showed increased left tonsillar uptake. Subsequent biopsy confirmed squamous cell carcinoma of the left tonsil. The demonstration of 3 synchronous primaries by PET is probably rare.

A 32-year-old man presented with asthenia, weight loss, cough, and dysphagia following a recent stay in Morocco. Endoscopy showed a bulky mass of the epiglottis suspected of being a malignant tumor. The patient underwent jointly an F-18 FDG PET/CT and a biopsy of the tumor. Against all expectations, biopsy revealed granulomatous inflammation with epitheloid giant cells and caeseating necrosis. These findings associated with the presence of acid-fast bacilli in the sputum smears were highly suggestive of laryngeal tuberculosis, which was confirmed later after cultivation of mycobacteria. F-18 FDG PET showed diffuse pharyngolaryngeal and lung uptake with bilateral cervical and abdominal nodes, but also one thoracic vertebral uptake. Lung CT could have revealed carcinomatous dissemination, but cavitary lesions in some pulmonary segments were more evocative of tuberculosis. Moreover, cerebral MRI showed brain tuberculomas not visualized on F-18 FDG PET/CT. The patient was treated with a 5-antituberculosis drug regimen, which improved clinical symptoms with epiglottis mass regression, and lung CT image reduction, clinching the systemic tuberculosis diagnosis. A control F-18 FDG PET/CT performed 5 months later showed disappearance of the pharyngolaryngeal and node uptake, with an improvement of lung uptake without normalization, arguing for persistent disease. Unexpected pathologic findings may be present in more than 3% of neck dissections. Although this is usually indolent, with the underlying SCC remaining the main prognostic determinate, it may significantly complicate postoperative management.

A 38-year-old man gradually developed gait instability, dysarthria, and dysphagia over two months associated with an elevated blood pressure after starting hemodialysis therapy for diabetic nephropathy. Brain MRI studies indicated vasogenic edema in the brainstem, extending from the lower midbrain to the upper medulla oblongata. The patient's high blood pressure was refractory to treatment, and his neurological disabilities and MRI abnormalities progressed. FDG-PET, MR spectroscopy, and cerebrospinal fluid studies did not suggest neoplastic pathologies. The patient was diagnosed with a brainstem variant of reversible posterior leukoencephalopathy syndrome, and received three courses of steroid pulse therapy. After the pulse therapy, the clinical manifestations and MR findings improved. By maintaining strict management of blood pressure and body water balance during hemodialysis, he did not experience any further clinical exacerbation, and the lesion on MR images continued to regress. Ten months after the pulse therapy, T1-weighted images showed slightly hyperintense signal. This case suggests that reversible posterior leukoencephalopathy syndrome (RPLS) may take a chronic clinical course without acute onset.
