Case of an atypical pituitary abscess

A pituitary abscess is a rare intrasellar infection. Correct identification can be challenging preoperatively given its non-specific symptoms and imaging findings. We report a case of a young woman presenting with secondary amenorrhea, visual field deficits and a 2.6 cm pituitary lesion diagnosed to be a craniopharyngioma. A concomitant unexpected pituitary abscess was diagnosed intraoperatively without associated meningeal symptoms.

Neurological Change

Object No definitive method of preventing visual field deficits after stereotactic radiosurgery for lesions near the optic radiation (OR) has been available so far. The authors report the results of integrating OR tractography based on diffusion tensor (DT) magnetic resonance imaging into simulated treatment planning for Gamma Knife surgery (GKS). Methods Data from imaging studies performed in 10 patients who underwent GKS for treatment of arteriovenous malformations (AVMs) located adjacent to the OR were used for the simulated treatment planning. Diffusion tensor images performed without the patient's head being secured by a stereotactic frame were used for DT tractography, and the OR was visualized by means of software developed by the authors. Data from stereotactic 3D imaging studies performed after frame fixation were coregistered with the data from DT tractography. The combined images were transferred to a GKS treatment-planning workstation. Delivered doses and distances between the treated lesions and the OR were analyzed and correlated with posttreatment neurological changes. Results In patients presenting with migraine with visual aura or occipital lobe epilepsy, the OR was located within 11 mm from AVMs. In a patient who developed new quadrantanopia after GKS, the OR had received 32 Gy. A maximum dose to the OR of less than 12 Gy did not cause new visual field deficits. A maximum dose to the OR of 8 Gy or more was significantly related to neurological change (p < 0.05), including visual field deficits and development or improvement of migraine. Conclusions Integration of OR tractography into GKS represents a promising tool for preventing GKS-induced visual disturbances and headaches. Single-session irradiation at a dose of 8 Gy or more was associated with neurological change.

The Relationship

The primary aim was to determine if somatosensory impairments alter the association between falls history and glaucoma severity. A secondary aim was to identify the activities of daily living that cause increased concern related to falling in glaucoma and their association with glaucoma severity. Established questionnaires about falls and fear of falling (FoF) were mailed to participants diagnosed with glaucoma. Ninety-eight participants responded. Self-reported feet numbness and tingling symptoms were used to determine the presence of somatosensory impairments. Self-reported falls in glaucoma are associated with visual field deficits in both eyes, particularly in the presence of somatosensory impairments. In addition, increased FoF levels are linked with worse visual field deficits in both eyes, especially when performing challenging walking tasks. Somatosensory impairments alter the relationship between falls risk and visual field deficits in glaucoma. This information may be helpful in identifying older workers at an increased risk of falling.

Abdominal Cyst

Giant abdominal cyst can lead to various non-specific symptoms such as abdominal bloating, nausea/vomiting, constipation due to its mass effect. In rarer circumstances, it can lead to bowel obstruction, hydronephrosis and even abdominal compartment syndrome. Hereby, we present a case of giant abdominal cyst in a young woman where its origin was a diagnostic dilemma despite exhausting all imaging techniques. A laparotomy was performed and the giant cyst was found to be originating from the left ovary. The final histopathology confirmed it as an ovarian benign serous cystadenoma. The patient made a fully recovery without any complications.
