Tailgut cyst is a very rare lesion of the retrorectal space seemingly derived from embryonic remnants of the tail gut which often causes rectal signs and symptoms. A unique case of this lesion presenting as a subcutaneous mass lateral to the coccyx is hereby described

A 20 year young man was referred to our institution with superior vena cava (SVC) syndrome, multiple lung opacities and a mass lesion in the right upper zone (RUZ). CT-guided FNAC from the mass lesion was consistent with the diagnosis of non-small cell lung carcinoma (NSCLC). A lump in his left testis was detected during clinical examination. Both FNAC and excisional biopsy of the testicular ma...

A 24-year-old woman with slowly progressive altered mental status and fevers was found to have multiple brain mass lesions. A characteristic branching vascular pattern on T2* MRI (figure 1D) was key to identifying these mass lesions as vascular in origin. CSF was inflammatory and serologic testing supported the diagnosis of systemic lupus erythematosus with concomitant CNS angiitis affecting de...

BACKGROUND Langerhans cell histiocytosis (LCH) is a rare disease involving clonal proliferation of cells with characteristics similar to bone marrow-derived Langerhans cells. The case of a young woman, affected by Turner syndrome and a solitary intraparenchymal LCH associated with an osteolytic lesion of the overlying skull, is presented. CASE DESCRIPTION The patient, with an insidious histor...

B rain-stem epidermoid cysts (ECs) are extremely rare, with only 20 cases reported in the literature. 1 The neurological symptoms depend on the location of the ECs. They may cause headaches, palsy and unsteady gait. Pathological laughter (PL) is an unusual manifestation of neurosurgical disease and had been described in rare conditions of brain-stem compression from the surrounding tumors. 2 Ho...

A rare clinical presentation of cerebral amyloid angiopathy is reported. Our patient presented with the clinical and radiological signs of a right frontal mass lesion suggesting a brain tumor, and a biopsy provided the diagnosis of cerebral amyloid angiopathy. A brief review of the pathology and clinical features of cerebral amyloid angiopathy is presented.

A case of anaerobic streptococcus brain abscess was reported in which the cerebral lesion appeared on CT as a ring-enhanced mass, and gas bubbles were seen following corticosteroid administration without antibiotics. Surgery revealed no encapsulation. Surgical drainage of the cavity and treatment with antibiotics and corticosteroid were ineffective. Excision of the abscess and treatment with ch...

Mr. A, a 50-year-old English-speaking Korean man, presented to the hospital with right scapular pain. CT of the chest showed two masses, and a CT-guided fine-needle aspiration biopsy study revealed poorly differentiated non-smallcell carcinoma of the lung. MRI of the brain, with and without gadolinium, showed neither a mass lesion nor abnormal enhancement suggestive of metastatic disease.
