Hunting mimics and chameleons: diagnostic difficulties in atypical acute ischaemic stroke.
The seemingly straightforward diagnosis of acute ischaemic stroke can be complicated by the presence of conditions presenting similarly to stroke, and atypical strokes presenting with confusing and non-classical signs. We present a diagnostic quest to disentangle the effects of a number of stroke mimics from those of an underlying bilateral cerebrovascular phenomena, where with appropriate treatment of the non-stroke conditions the patient was able to make a near complete neurological recovery.

There are many causes for the paralysis of the external sciatic popliteal nerve , such as the intraneural ganglion cyst. In this case, we evaluate a 52-year-old woman with no relevant personal record, who was admitted with paresis of the right foot of 4 months of evolution associated with alterations in the sensitivity that rose up to the posterolateral region of the leg. The diagnosis was based on MR and cyst decompression and disconnection of the articular branch. ⋯ The most widely accepted theory is the unifying articular theory described by Spinner in the year 2003. Intraneural ganglion cysts must be included in the differential diagnosis of progressive paralysis of the sciatic nerve, lesions of the nerve root at L5 and nerve sheath tumours that start at the lateral compartment of the knee. The treatment of a fibular intraneural ganglion cyst must be surgical and the operation must be performed as soon as possible.

This case report describes two cases of dilated cardiomyopathy due to hypocalcaemia as a result of hypoparathyroidism. Patient A suffered from dilated cardiomyopathy due to secondary hypoparathyroidism as a result of previous neck surgery. Patient B suffered from dilated cardiomyopathy with congestive heart failure due to primary hypoparathyroidism. ⋯ Besides standard treatment of heart failure, restoration of serum calcium levels with calcium and vitamin D supplementation can lead to rapid improvement of cardiac function and should be continued lifelong. Both patients were responding very well to heart failure therapy and calcium supplementation as ejection fraction improved after restoration of plasma calcium levels. This case report emphasises that hypocalcaemia should be in the differential diagnosis of heart failure.

A 23-year-old woman presented to the emergency department (ED) with a 3-day history of lower back pain. She had seen her general practitioner 2 days previously who prescribed trimethoprim for a confirmed urinary tract infection. Routine admission observations showed she was tachycardic, tachypnoeic and slightly hypotensive but non-feverish with normal oxygen saturations. ⋯ She was subsequently referred to the obstetrics and gynaecology registrar who on examination found she had a gravid uterus and vaginal examination revealed that her cervix was 8 cm dilated. The patient was very promptly admitted onto the labour ward for further assessment. She gave birth to a live male infant in the early hours of the next morning.

The management of primary and secondary radial nerve palsy associated with humeral shaft fractures is still controversial. Radial nerve function is likely to return spontaneously after primary as well as secondary radial nerve palsy in the absence of any level of neurotmesis. ⋯ During exploration of the radial nerve and surgical revision of the fracture, we found the nerve entrapped by the plate and partially transected by a screw. Full recovery of radial nerve function occurred after neurolysis and microscopic neurorrhaphy.
