[Treatment Options for Adenoid Cystic Lacrimal Gland Carcinoma - A Case Series and Literature Review].

Adenoid cystic carcinoma of the lacrimal gland (ACC) is a rare malignant orbital tumour with a poor overall prognosis. Current therapeutic approaches like radical and local surgery, adjuvant radiation and neoadjuvant intra-arterial chemotherapy are controversial. We present three cases of patients with ACC with different therapy concepts and discuss these with current recommendations from the literature.

[Impact of anamnestic information and neurological deficits on the detection rate of secondary headaches].

Purpose: Headaches are a very common symptom and imaging is important to rule out symptomatic causes. For clinical differentiation between primary and secondary headaches an exact anamnesis and neurological examination are important. The aim of this study is therefore to identify anamnestic and neurological information that is associated with secondary headaches.

Gadolinium-based contrast agents induce gadolinium deposits in cerebral vessel walls, while the neuropil is not affected: an autopsy study.

Recent studies showed gadolinium depositions following serial administrations of gadolinium-based contrast agents (GBCAs) for magnetic resonance imaging examinations in various parts of the brain with the dentate nucleus (DN) being most affected. Even though no clinical correlates of the deposits are known yet, an intensive debate developed if this might be harmful. The aim of the current study was to specify the gadolinium distribution in brain tissue of patients who received serial injections of GBCAs in the low-µm range and to explore any potential pathological tissue changes caused by gadolinium deposits.

Prostate-Specific Membrane Antigen-Negative Metastases-A Potential Pitfall in Prostate-Specific Membrane Antigen PET.

Ga-PSMA-11 PET/CT was performed in a 74-year-old man because of biochemical recurrence of prostate cancer following radiation therapy of the prostate gland 24 months earlier. Besides focal nuclide accumulation in the prostate gland suggestive of local recurrence, PET scan revealed no further pathologic uptake. However, CT showed multiple pulmonic nodules suggestive of metastases.
