Phaeohyphomycosis belongs to a heterogeneous group of fungal infections, originally described by Ajello et al . as mycoses, whose etiologic agents develop in host tissue as dark-walled, septate mycelial elements. Disseminated infections occur in immunocompromised patients, involving the paranasal sinuses, eyes, central nervous system, lymph nodes, and bone. We present here an interesting image of 18 F fluorodeoxyglucose positron-emission tomography/computed tomography showing scapula osteomyelitis caused by phaeohyphomycosis.

Antiglutamic acid decarboxylase-65 (anti-GAD65) autoantibodies have been identified in variety of rare neurologic disorders most frequently in stiff-person syndrome (SPS), condition characterized by muscle rigidity and overlying painful spasms, typically affecting axial and limb musculature. In anti-GAD65-related neurologic disorder, malignancy screening is often performed with 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Here, we present an interesting image of 18FFDG PET/CT whole body showing muscle uptake and FDG brain showing thalamic hypometabolism in SPS.

Morvan's syndrome (MoS) is a rare, complex neurological disorder characterized by neuromyotonia, neuropsychiatric features, dysautonomia, and neuropathic pain. The majority of MoS cases have a paraneoplastic etiology, most commonly thymoma, usually occurring before the diagnosis of the underlying tumor and showing improvement following surgery. We present a case of 60-year-old patient presenting with suspicious of MoS and autoimmune encephalitis (AE), F-18 fluorodeoxyglucose positron emission tomography/computed tomography as single imaging modality detected and confirmed both AE and thymoma.
