Abstract

Purpose

Arachnoid cysts may present with symptoms deriving from cyst rupture, usually causing intracystic hemorrhage and subdural hematoma or hygroma. Rupture is usually caused by minor trauma, spontaneous rupture is an exceptional event, and 57 cases have been described in literature. We here present and discuss the largest series of spontaneously ruptured middle fossa arachnoid cysts in order to investigate clinical presentation and best treatment available.

Methods

We report a retrospective series of 17 pediatric patients surgically treated for middle fossa arachnoid cyst with signs of cyst rupture without a history of trauma in the previous 90 days. We describe clinical presentation, treatment, and outcome at follow-up discussing our results with a literature review including all reported cases of spontaneous rupture of middle fossa arachnoid cysts.

Results

In our experience patients most frequently presented with subdural hygroma, in literature, a chronic hematoma was most frequently reported. Headache is the most reported symptom at presentation. Neurological deficits and consciousness alterations are rare. Surgical treatment may resolve brain compression only or reduce rupture recurrence risk. Conservative treatment has also been proposed. Different treatments are reported and discussed focusing on indications, contraindications, risks, and expected benefits.

Conclusion

We propose, when safely possible, microsurgical cyst fenestration in skull base cisterns as the treatment of choice for these patients as long as it addresses both immediate decompression and risk of rupture recurrence. We report good outcomes and low incidence of complications from our series with a mean postoperative follow-up of 30 months.

Leitlinienkonformes Management thermischer Verletzungen

Thermische Verletzungen gehören zu den schwerwiegendsten Traumen und hinterlassen oft langfristige körperliche und psychische Spuren. Die aktuelle S2k-Leitlinie „Behandlung thermischer Verletzungen im Kindesalter (Verbrennung, Verbrühung)“ bietet eine strukturierte Übersicht über das empfohlene Vorgehen.

Verbände und Cremes gegen Dekubitus: „Wir wissen nicht, was sie bringen!“

Die Datenlage zur Wirksamkeit von Verbänden oder topischen Mitteln zur Prävention von Druckgeschwüren sei schlecht, so die Verfasser einer aktuellen Cochrane-Studie. Letztlich bleibe es unsicher, ob solche Maßnahmen den Betroffenen nutzen oder schaden.

Nackenschmerzen nach Bandscheibenvorfall: Muskeltraining hilft!

Bei hartnäckigen Schmerzen aufgrund einer zervikalen Radikulopathie schlägt ein Team der Universität Istanbul vor, lokale Steroidinjektionen mit einem speziellen Trainingsprogramm zur Stabilisierung der Nackenmuskulatur zu kombinieren.

US-Team empfiehlt Gastropexie nach Hiatushernien-Op.

Zur Vermeidung von Rezidiven nach Reparatur einer paraösophagealen Hiatushernie sollte einem US-Team zufolge der Magen bei der Op. routinemäßig an der Bauchwand fixiert werden. Das Ergebnis einer randomisierten Studie scheint dafür zu sprechen.
