(This case study was added to OER Commons as one of a batch of over 700. It has relevant information which may include medical imagery, lab results, and history where relevant. A link to the final diagnosis can be found at the end of the case study for review. The first paragraph of the case study -- typically, but not always the clinical presentation -- is provided below.)
A right-handed 14 year-old boy was admitted for a first unprovoked generalized tonic clonic seizure, which was preceded by ongoing headache and nausea for a few days. His parents also noted a sharp decline in his academic performance in recent months. Physical examination was unremarkable except for the presence of right homonymous superior quadrantanopia. Psychological assessment revealed impairment in his verbal memory and learning. Blood results and EEG were unremarkable. Imaging of the brain by CT showed a left temporal mass with calcifications and hemorrhage (Figure 1), and MRI revealed a large avidly contrast-enhancing left temporal mass measuring 4 x 5 x 4cm with evidence of recent hemorrhage (Figures 2 and 3). There were foci of edema and mass effects causing compression of the left temporal horn with adjacent sulcal effacement (Figure 4). He underwent gross total tumor resection under ultrasound guidance via a left temporal craniotomy.

A 48 years-old patient without significant medical history or without bleeding disorder is addressed to our institution for acute headache and bitemporal hemianopsia. No hormonal secretion was detected, and the patient had a pituitary insufficiency with loss of libido, diffuse hair loss, asthenia and slowing. An MRI showed a 47mm pituitary lesion occupying the sella turcica with central necrosis. This lesion was hypointense in T1 sequence, enhanced with gadolinium injection and hyperintense in T2 sequence (Fig.1). Then, a transsphenoidal excision surgery was decided. A first surgery was performed, but the resection of the tumor lead to an extensive bleeding and the tumor could not be resected entirely. Three days later, because of incomplete resection a second excision procedure was decided leading to an extensive bleeding and a subtotal surgical resection. The visual symptoms of the patient improved quickly after the surgery.

A 52 year old man with an unremarkable clinical history started to complain of daily somnolence, unusual irritability and some memory lapses. A few months later, he had fever and developed confusion with myoclonic jerks of the left limbs. Upon admission a diagnosis of encephalitis was made. MRI FLAIR images (Figure 1 A, B) showed cortical and sub-cortical abnormal signal intensity in parasagittal posterior frontal and anterior parietal regions, compatible with ischemic damage in watershed areas. On coronal T1-weighted image (insert in Figure 1A) cortex was hyperintense for petechial hemorrhage. Multivoxel Proton Magnetic Resonance Spectroscopy (1 H-MRS) demonstrated lactic acid in the lesions (Figure 1C, arrows). The CSF showed 10 white cells / ml with normal protein and glucose. He was treated with antibiotics, acyclovir, steroids and immunoglobulins and improved so that he was discharged to a rehabilitation facility. The patient could play chess and walk around with the help of a walking frame.
